Avago Technologies (now Broadcom) offers the HCPL-785x hermetic analog isolation amplifier in multiple lead configurations to accommodate different PCB assembly processes. The HCPL-7850#300 is the gull wing surface mount variant of the HCPL-7850 — the same 8-pin hermetically sealed ceramic DIP package with leads cut and bent into a gull wing profile for reflow SMT assembly, with solder-dipped lead finish. The HCPL-7850#300 is available from stock at Sparkle Electronics, a specialized distributor of high-reliability and military-capable electronic components serving defense contractors, avionics systems integrators, and industrial power electronics engineers worldwide. The #300 option resolves the single constraint that prevents the standard through-hole HCPL-7850 from being used in modern SMT-only board designs: the gull wing lead form allows the hermetic ceramic package to be placed and reflowed using standard surface mount processes without drilling through-hole vias.

Every electrical specification of the HCPL-7850#300 is identical to the standard HCPL-7850 — the sigma-delta ADC to DAC architecture, 8.00 V/V gain at 5% tolerance, 0.1% nonlinearity, 100 kHz bandwidth, 8 kV/µs common mode rejection, and guaranteed −55°C to +125°C operation are all preserved. The difference is assembly method only: gull wing SMT replaces through-hole insertion, making the HCPL-7850#300 directly applicable to high-density avionics systems PCBs and defense power electronics assemblies built to SMT manufacturing processes. For programs requiring MIL-PRF-38534 Class H screening in the same gull wing configuration, the HCPL-7851#300 is the qualified variant.

One Option Number, One Assembly Advantage: Understanding HCPL-7850#300

The HCPL-7850#300 exists for a specific and practical procurement reason: modern defense and avionics PCB designs are increasingly built to pure SMT processes where through-hole component insertion is either eliminated from the assembly line or introduces additional handling cost and complexity. The standard HCPL-7850 through-hole package cannot be placed and reflowed — it requires a separate insertion and wave soldering or hand soldering step. The #300 gull wing option eliminates this constraint entirely, placing the hermetic analog isolation amplifier on the same assembly pass as every other SMT component on the board.

The gull wing (#300) is correct for standard SMT reflow assembly. The butt joint (#100) suits boards where component height is minimized and the package stands flat against the board surface. The standard through-hole is used on boards where SMT is not required. All three are electrically identical — the selection is driven entirely by PCB assembly process.

Sigma-Delta Analog Isolation: Why Architecture Determines Accuracy Over Temperature

The HCPL-7850#300 inherits the core architecture advantage of the HCPL-785x family: because the optical coupling path transmits a digital bit stream rather than an analog signal, the accuracy specifications — gain, nonlinearity, offset — are determined by the ADC and DAC, not by LED-phototransistor characteristics. This means the 0.1% nonlinearity and 8.00 V/V gain hold across the full −55°C to +125°C temperature range without trimming or compensation. For defense power electronics operating across this range — motor controllers in military vehicles, inverters in aerospace and defense ground power systems, current sensing in satellite and space power management — this temperature stability is a direct reliability advantage over conventional analog optocoupler isolation methods.

Within the Avago hermetic portfolio at Sparkle Electronics, the AVAGO HCPL-7850 through-hole version is the correct choice for boards built to traditional through-hole or mixed assembly processes. For the full range of hermetic digital optocoupler isolation — from 100 KBd Darlington output to 40 Mbps logic gate — the AVAGO HCPL-5201 (5962-88768), AVAGO HCPL-5430, and AVAGO HCPL-6631 (8102802) cover the digital isolation spectrum.

Frequently Asked Questions

What is the difference between HCPL-7850#300 and HCPL-7850?

The only difference is the lead form. HCPL-7850#300 has leads cut and bent into a gull wing profile for SMT reflow assembly with solder-dipped finish. The standard HCPL-7850 has straight through-hole leads with gold plate finish. All electrical specifications — gain, nonlinearity, bandwidth, CMR, offset, isolation voltage, temperature range — are identical. Boards migrating from through-hole to SMT assembly select the #300 option without any circuit redesign.

Where can I buy HCPL-7850#300 in stock?

Sparkle Electronics stocks the HCPL-7850#300 for defense, avionics, and industrial power electronics procurement. Contact our team for current pricing, available quantity, and confirmed lead time. Same-day response on qualified inquiries.

Does the #300 gull wing option affect the military temperature range?

No. The HCPL-7850#300 operates and stores across the full −55°C to +125°C military temperature range, identical to the standard through-hole HCPL-7850. The lead forming process does not affect the hermetic seal or the die electrical characteristics. The gull wing option is a mechanical assembly convenience — not an electrical or environmental compromise.

What is the DLA SMD number for the gull wing hermetic version?

The Class H gull wing variant (HCPL-7851#300) carries DLA SMD number 5962-9755701HXA. The commercial HCPL-7850#300 does not have an SMD number — it is not a MIL-PRF-38534 screened part. For programs requiring DLA QML traceability, the HCPL-7851#300 under SMD 5962-9755701HXA is the correct specification. Contact Sparkle Electronics to confirm Class H gull wing availability.

Can HCPL-7850#300 be used in high-density avionics line-replaceable units?

Yes. The gull wing lead form is specifically designed for high-density SMT boards where through-hole components cannot be accommodated. The hermetic ceramic package satisfies moisture resistance requirements for airborne environments, and the −55°C to +125°C temperature range covers avionics LRU operating conditions. The 8 kV/µs CMR at 1000V is sufficient for most avionics power domain isolation requirements. Contact us for application-specific design support.

Is there a tape-and-reel option for HCPL-7850#300?

The #300 gull wing option is typically packaged 50 units per tube. A tape-and-reel version (if available) would be designated with additional suffix codes. For volume procurement requirements or alternative packaging requests, contact Sparkle Electronics to confirm available packaging formats and lead time.
