Avago Technologies (now Broadcom) designed the HCPL-5430 as the dual-channel hermetically sealed counterpart to the commercial HCPL-2430, delivering two independent 40 Mbps isolation channels within a single 8-pin ceramic DIP package rated across the full military temperature range. The HCPL-5430 is available from stock at Sparkle Electronics, a specialized distributor of high-reliability and defense-grade electronic components serving prime contractors, avionics systems integrators, and government procurement offices worldwide. Manufactured and tested on a MIL-PRF-38534 certified line and included in the DESC Qualified Manufacturers List QML-38534 for hybrid microcircuits, the HCPL-5430 is dual-marked with both the Avago/Broadcom part number and the DESC Drawing Number — meeting the dual-marking traceability requirement of DLA QML defense procurement.
The defining procurement rationale for the HCPL-5430 over the single-channel HCPL-5400 is package density: two independent 40 Mbps isolation channels in the same 8-pin ceramic DIP footprint as the single-channel device, halving the board area and component count for multi-channel isolation requirements. In avionics systems digital backplanes, radar and electronic warfare processor interfaces, and isolated military data bus implementations where multiple high-speed channels must cross an isolation barrier simultaneously, the HCPL-5430 consolidates two channels into one hermetically qualified package — directly reducing reliability-critical solder joint count and board real estate.

Two Channels, One Package: The HCPL-5430’s Value Proposition in Defense PCB Design
Defense PCB designers managing hermetic optocoupler placement face a consistent constraint: every isolated channel adds a discrete component, a solder joint pair, and a footprint allocation on a board where every square millimeter has a reliability and weight cost. The HCPL-5430 resolves this for applications requiring two 40 Mbps isolation channels by placing both in a single hermetically sealed 8-pin ceramic DIP — functionally equivalent to two HCPL-5400 single-channel devices at half the board footprint and component count.

HCPL-5430 vs. HCPL-5400 vs. HCPL-5201: Selecting the Right Hermetic Optocoupler
| Parameter | HCPL-5430 | HCPL-5400 | HCPL-5201 |

| SMD | DESC Drawing | DESC Drawing | 5962-88768 |
| Commercial Equivalent | HCPL-2430 | HCPL-2400 | HCPL-2201 |
The selection logic is straightforward: choose HCPL-5201 when the signal rate is 5 MBd or lower and high CMR (>10 kV/µs typical) is the priority; choose HCPL-5400 when 40 Mbps single-channel speed is required; choose HCPL-5430 when two 40 Mbps channels are needed in a single hermetic package to maximize board density. All three devices carry identical MIL-PRF-38534 Class H/K qualification and QML-38534 listing — the choice is driven by channel count, speed, and CMR requirements, not qualification level.
Understanding the Commercial-to-Hermetic Upgrade Path
For defense programs transitioning from HCPL-2430 commercial designs to hermetically qualified production hardware, the HCPL-5430 provides a direct function-compatible hermetic equivalent. The pin assignment, logic interface, and operating voltage range are preserved — the upgrade from plastic commercial package to hermetic ceramic DIP requires no schematic change and no logic redesign. This makes the HCPL-5430 the natural hermetic qualification path for programs that prototyped with HCPL-2430 and must now meet hermetic packaging and QML-38534 traceability requirements for fielded defense hardware. Sparkle Electronics maintains stock of both AVAGO HCPL-5400 (single-channel) and AVAGO HCPL-5201 (5 MBd single-channel) for programs with different channel count or speed requirements within the same hermetic optocoupler qualification framework.
Frequently Asked Questions
What does HCPL-5430 decode to?
HCPL = Hewlett-Packard Coupled Product Line (original HP optocoupler series designation, now Broadcom); 54 = hermetically sealed very high speed logic gate optocoupler family; 30 = dual-channel variant. The HCPL-5400 is the single-channel counterpart; the HCPL-5431 is a related variant with different output configuration in the same family.
Where can I buy HCPL-5430 in stock?

What is the difference between HCPL-5430 and HCPL-5400?
Both are 40 Mbps hermetically sealed logic gate optocouplers in 8-pin ceramic DIP packages with identical qualification (MIL-PRF-38534 Class H/K, QML-38534). The HCPL-5430 contains two independent isolation channels; the HCPL-5400 contains one. The dual-channel HCPL-5430 is the correct choice when two 40 Mbps isolation channels are required in a single hermetic package, halving board area and component count relative to two discrete HCPL-5400 devices.
Is HCPL-5430 a direct replacement for HCPL-2430?
Yes, functionally. The HCPL-5430 is the hermetically sealed, MIL-PRF-38534 qualified version of the commercial HCPL-2430. Pin assignment, logic interface architecture, and operating voltage range are preserved between the two. The hermetic ceramic package, military temperature range guarantee, and QML-38534 certification are what differentiate them. Programs transitioning from HCPL-2430 to hermetically qualified production parts can substitute the HCPL-5430 without circuit redesign.
What does the 500 V/µs CMTI mean for system design?
500 V/µs is the guaranteed common mode transient immunity — the maximum rate of common mode voltage change the device can withstand while maintaining correct logic output. In defense applications with high dV/dt switching events on the isolated side, such as power converter transitions or bus fault conditions, the CMTI specification defines the isolation barrier’s robustness. At 500 V/µs, the HCPL-5430 is suited for moderate common mode environments. Applications requiring >10 kV/µs CMTI should reference the HCPL-5201 family, which achieves higher CMR at lower data rates.
Can HCPL-5430 be used in space applications?
Yes. The high radiation immunity, MIL-PRF-38534 Class K availability, hermetic ceramic packaging, and full military temperature range make the HCPL-5430 applicable to satellite and space programs. Class K screening must be specified for space-grade procurement. Contact Sparkle Electronics to confirm Class K availability and lead time for your program.
