JANTX1N938B-1 Technical Overview: Verified Parameters Before Sourcing
MICROSEMI JANTX1N938B-1 is a programmable logic device cataloged in FPGA & CPLD, Power Modules & Discretes for Aerospace & Defense, Radar & Electronic Warfare, Satellite & Space programs. Unlike a family-level listing, the complete ordering code matters: package, temperature grade, speed option, screening level and shipment format can change with a suffix. The structured reference data for this exact part identifies Package/Case Hermetic axial DO-35 / DO-204AH, Device Type Temperature-compensated Zener voltage-reference diode, Nominal Reference Voltage 9.0 V, Zener Voltage Range 8.55 V to 9.45 V.
These values are useful for initial BOM and sourcing review, but engineering approval should still use the latest manufacturer-controlled datasheet, package drawing and change notices. For availability, lot/date code and documentation, send Sparkle Electronics the complete JANTX1N938B-1 requirement.

What the Specifications Mean in a Design Review
For this programmable logic device, the main compatibility checks are logic density, I/O count, speed grade, configuration flow, package escape routing, power rails and toolchain support. A replacement should not be approved from the family name alone. The values below need to be checked against the schematic, PCB footprint, power tree, timing constraints, thermal analysis and program qualification baseline:
- Package/Case: Hermetic axial DO-35 / DO-204AH
- Device Type: Temperature-compensated Zener voltage-reference diode
- Nominal Reference Voltage: 9.0 V
- Zener Voltage Range: 8.55 V to 9.45 V
- Test Current: 7.5 mA
- Maximum Zener Impedance: 20 Ω
- Temperature Range: -55°C to +150°C
Minimum and maximum values are not interchangeable with typical test values, and package-level compatibility does not guarantee pin, timing or firmware compatibility. Where the assembly is used in high-reliability equipment, confirm the required screening, traceability, lead finish and environmental documentation before purchase.
JANTX1N938B-1 and Related MICROSEMI Devices
The following pages provide useful internal comparison points. They are related sourcing options, not automatically drop-in replacements:
- MICROSEMI JANTX1N5907 — compare the exact architecture, package, speed or grade before substitution.
- MICROSEMI JANTX2N6796 — compare the exact architecture, package, speed or grade before substitution.
- MICROSEMI JANTX2N3441 — compare the exact architecture, package, speed or grade before substitution.
- MICROSEMI ZL30160GGG2 — compare the exact architecture, package, speed or grade before substitution.
When comparing these devices, start with the exact function and architecture, then verify package and pinout, voltage rails, speed or bandwidth, operating temperature and qualification grade. If any of those differ, an engineering redesign or requalification may be required.
Package, Temperature and Ordering-Code Checks
The orderable code JANTX1N938B-1 must be kept intact on the RFQ. Confirm the manufacturer marking, package drawing, terminal finish, moisture handling, operating-temperature requirement and packing format. For obsolete or long-stored material, define acceptable date codes and inspection criteria before quotation rather than after delivery.
Sourcing teams should also request the documentation appropriate to the program: Certificate of Conformance, packing and label photographs, lot/date-code information, traceability, visual inspection, X-ray or electrical testing when required. See our quality-control approach and the broader FPGA & CPLD, Power Modules & Discretes selection.
Applications and Procurement Context
JANTX1N938B-1 may be evaluated for Aerospace & Defense, Radar & Electronic Warfare, Satellite & Space systems where its verified electrical limits, package and temperature range match the approved design. Typical work includes new production, repair, lifecycle extension and last-time-buy planning. Application labels describe catalog relevance; final suitability remains a system-level engineering decision.
