Product details
Overview
JANS1N6137US/TR from Microsemi (now Microchip) is a hermetically sealed, military-grade 15 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 avionics power rails.
For engineers reviewing the JANS1N6137US/TR datasheet, JANS1N6137US/TR pinout, JANS1N6137US/TR application, or JANS1N6137US/TR equivalent, key selection criteria include Zener voltage accuracy under MIL-PRF-19500/507 screening, low dynamic impedance at 25 mA test current, and compliance with JAN/JANTXV reliability levels for high-reliability analog circuits.
Technical Context
This device operates as a two-terminal voltage reference and clamping element, with breakdown characterized at IZT = 25 mA and specified ZZT ≤ 15 Ω. It meets MIL-PRF-19500 Class V screening requirements including temperature cycling, burn-in, and lot acceptance testing.
The JANS1N6137US/TR exhibits stable Zener voltage over -65°C to +175°C ambient, with maximum leakage current of 5 µA at 12 V reverse bias and thermal resistance (RθJA) of 80°C/W in free air per DO-41 mounting guidelines.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 15 V ±5% at IZT = 25 mA - ensures stable reference in regulated supplies requiring tight tolerance |
| Power Dissipation (PZM) | 1.5 W - supports continuous operation in high-reliability linear regulator feedback paths |
| Zener Impedance (ZZT) | ≤15 Ω at IZT = 25 mA - minimizes output voltage variation under load transients |
| Reverse Leakage (IR) | ≤5 µA at 12 V - maintains low quiescent current in standby-critical avionics circuits |
| Response Time | 100 ns - enables effective suppression of fast-rising ESD and switching noise |
| Operating Temperature | -65°C to +175°C - qualified for extended-range deployment in engine-mounted electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6137US | Same Zener voltage and DO-41 package; screened to JANTXV level (MIL-PRF-19500/507 Class H), not Class V | Limited to non-safety-critical subsystems where full Class V burn-in and lot testing are not mandated | Select JANTXV1N6137US only if program specifications allow Class H screening and reduced lifetime validation. |
| 1N6137A-1 | Commercial-grade variant; same 15 V rating but ±10% tolerance, no military screening, 500 mW PZM | Restricted to ground-based test equipment or non-flight hardware with relaxed reliability requirements | Use 1N6137A-1 only for prototyping or cost-sensitive non-military applications where 1.5 W dissipation and Class V qualification are unnecessary. |
Compared with JANTXV1N6137US and 1N6137A-1, the JANS1N6137US/TR delivers superior long-term stability and transient robustness due to its Class V screening, hermetic seal, and higher power rating - essential for flight-critical voltage references where field failure is unacceptable.

FAQ
What is the Zener voltage tolerance for JANS1N6137US/TR?
The JANS1N6137US/TR has a Zener voltage tolerance of ±5% at 25 mA test current, meaning its nominal 15 V breakdown occurs between 14.25 V and 15.75 V under specified conditions. This tighter tolerance than commercial equivalents supports precision regulation in flight-critical analog circuits where voltage drift directly impacts system accuracy. The JANS1N6137US/TR maintains this tolerance across its full military temperature range.
Is JANS1N6137US/TR hermetically sealed?
Yes, the JANS1N6137US/TR uses a hermetically sealed DO-41 glass package, which prevents moisture ingress and ensures long-term parametric stability in harsh environments. This sealing method is required for MIL-PRF-19500/507 Class V qualification and contributes to the JANS1N6137US/TR's ability to retain specification compliance over 20+ years in sealed avionics enclosures.
What screening level does JANS1N6137US/TR meet?
The JANS1N6137US/TR meets MIL-PRF-19500/507 Class V screening requirements, including temperature cycling, steady-state life test, burn-in, and lot acceptance testing. This highest-tier screening level distinguishes the JANS1N6137US/TR from lower-class variants like JANTXV and confirms its suitability for safety-critical applications where zero latent defects are mandatory.
Can JANS1N6137US/TR replace JANTXV1N6137US in existing designs?
The JANS1N6137US/TR is physically and electrically compatible with JANTXV1N6137US - same DO-41 package, 15 V Zener voltage, and 25 mA test current - but provides enhanced reliability via Class V screening. Replacing JANTXV1N6137US with JANS1N6137US/TR requires no PCB changes and improves long-term stability, though formal requalification may be needed per program-specific configuration control requirements.
What is the maximum power dissipation of JANS1N6137US/TR?
The JANS1N6137US/TR has a maximum power dissipation (PZM) of 1.5 W under free-air conditions, enabling sustained operation in high-reliability linear regulator feedback paths and transient suppression circuits. This rating is validated per MIL-PRF-19500/507 test methods and remains stable across the full -65°C to +175°C operating temperature range specified for the JANS1N6137US/TR.
