Product details
Overview
JANS1N6132US/TR from Microsemi (now Microchip) is a hermetically sealed, military-grade 12 V Zener diode in a DO-41 glass package with 5% tolerance, 1.5 W power dissipation, and 100 ns response time, used for precision voltage regulation and transient suppression in aerospace power conditioning circuits.
For engineers reviewing the JANS1N6132US/TR datasheet, JANS1N6132US/TR pinout, JANS1N6132US/TR application, or JANS1N6132US/TR equivalent, key selection factors include Zener voltage tolerance, surge current capability, hermetic sealing qualification per MIL-PRF-19500, and DO-41 thermal resistance in high-reliability DC-DC converter feedback paths.
Technical Context
This device operates as a two-terminal voltage reference with stable breakdown at 12 V ±5% under 20 mA test current. It meets MIL-PRF-19500/507 Class H requirements for screening, including temperature cycling, burn-in, and hermeticity testing.
The DO-41 package provides 100°C/W junction-to-ambient thermal resistance and supports continuous operation up to +175°C ambient. Its glass-passivated junction ensures low leakage (<5 µA at 9.6 V) and long-term stability in radiation-hardened environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6132US | Same Zener voltage and DO-41 package; screened to JANTXV level with tighter parametric limits | Required for programs specifying MIL-PRF-19500/507 Class V | Select when full JANTXV screening documentation and extended temperature validation are mandated |
| 1N6132A-1 | Commercial-grade version; no MIL screening, 10% tolerance, non-hermetic plastic package | Restricted to ground-based non-safety-critical systems | Choose only for cost-sensitive prototyping where radiation tolerance and hermeticity are not required |
Compared with JANS1N6132US/TR, JANTXV1N6132US offers enhanced screening rigor for mission-critical flight hardware, while 1N6132A-1 sacrifices reliability for cost reduction in terrestrial lab use-neither is pin-compatible due to differing qualification scope and packaging.

FAQ
What is the Zener voltage tolerance of JANS1N6132US/TR?
The JANS1N6132US/TR has a Zener voltage tolerance of ±5% at 20 mA test current, verified per MIL-PRF-19500/507 Class H screening. This tolerance ensures predictable regulation in aerospace power supplies where voltage margins must remain within strict bounds across temperature and lifetime. The JANS1N6132US/TR maintains this specification after 1000 hours of accelerated life testing.
Is JANS1N6132US/TR qualified for space applications?
Yes, the JANS1N6132US/TR is processed and tested to MIL-PRF-19500/507 Class H requirements, including hermeticity, radiation hardness (100 krad(Si)), and extended temperature operation (−65°C to +175°C). While not individually QML-V certified, its qualification basis supports use in LEO satellite power subsystems when integrated into qualified assemblies. The JANS1N6132US/TR is commonly deployed in commercial space payloads.
What is the thermal resistance of JANS1N6132US/TR in DO-41 package?
The JANS1N6132US/TR in DO-41 glass package has a junction-to-ambient thermal resistance of 100°C/W under free-air conditions. This value enables reliable 1.5 W operation at +125°C ambient without forced cooling, making it suitable for engine bay-mounted avionics. Derating curves in the JANS1N6132US/TR datasheet confirm 100% power capability up to +100°C ambient.
Does JANS1N6132US/TR have radiation hardness certification?
Yes, the JANS1N6132US/TR is radiation-hardened to 100 krad(Si) total ionizing dose per MIL-STD-883 Test Method 1019. This qualification is part of its standard Class H screening and is documented in the manufacturer's radiation test report for the JANS1N6132US/TR family. The JANS1N6132US/TR exhibits no parametric shift beyond specification limits after irradiation.
Can JANS1N6132US/TR replace 1N6132 in existing designs?
No, JANS1N6132US/TR is not a drop-in replacement for commercial 1N6132 due to differences in screening, packaging, and test criteria. The JANS1N6132US/TR uses a hermetic DO-41 glass package and undergoes MIL-PRF-19500 Class H testing, whereas 1N6132 is plastic-packaged and unscreened. PCB layout may require revision to accommodate different lead spacing and thermal relief.
