Product details
Overview
JANS1N6136AUS/TR from Microsemi (now Microchip) is a hermetically sealed, military-grade 200 V Zener diode in a DO-213AB (MELF) glass package, rated for 500 mW power dissipation, ±5% voltage tolerance, and operating across –65°C to +175°C. It serves as a precision voltage reference and overvoltage clamp in radiation-hardened avionics power regulation circuits.
For engineers reviewing the JANS1N6136AUS/TR datasheet, JANS1N6136AUS/TR pinout, JANS1N6136AUS/TR application, or JANS1N6136AUS/TR equivalent, key selection factors include its MIL-PRF-19500/514 qualification, low dynamic impedance (Zzt = 1000 Ω max at Izt = 1 mA), and guaranteed parameter stability under total ionizing dose (TID) up to 100 krad(Si).
Technical Context
This device belongs to the JANS-class screened version of the 1N6136A series, meeting Class S screening per MIL-PRF-19500. It is designed for use in fixed-voltage regulation and transient suppression where long-term parametric stability under extreme thermal cycling and ionizing radiation is mandatory.
The Zener breakdown mechanism operates in the avalanche region above 6.8 V, ensuring predictable knee characteristics and minimal voltage drift over lifetime. Its hermetic glass-metal seal and gold-plated MELF terminations support reliable solder joint integrity in high-reliability PCB assemblies.

FAQ
What is the Zener voltage tolerance for JANS1N6136AUS/TR?
The JANS1N6136AUS/TR has a Zener voltage tolerance of ±5% at 200 V nominal, verified per MIL-PRF-19500/514 Class S testing. This tight tolerance ensures predictable clamping behavior in safety-critical power rails where overvoltage margins must remain strictly bounded. The JANS1N6136AUS/TR maintains this specification across its full operating temperature range and after radiation exposure up to 100 krad(Si).
Is JANS1N6136AUS/TR hermetically sealed?
Yes, the JANS1N6136AUS/TR uses a hermetic glass-metal seal in the DO-213AB (MELF) package, certified per MIL-STD-883 Method 1014. This construction prevents moisture penetration and parametric drift during extended operation at 175°C ambient. The JANS1N6136AUS/TR's hermeticity is validated through fine-leak helium testing as part of Class S screening.
Does JANS1N6136AUS/TR meet MIL-PRF-19500 requirements?
Yes, the JANS1N6136AUS/TR is fully qualified to MIL-PRF-19500/514 Class S, including 168-hour burn-in, 5x temperature cycling between –65°C and +175°C, and hermeticity verification. This qualification confirms the JANS1N6136AUS/TR meets the electrical, mechanical, and environmental requirements for high-reliability military and aerospace applications.
What is the maximum power dissipation of JANS1N6136AUS/TR?
The JANS1N6136AUS/TR is rated for 500 mW steady-state power dissipation at 25°C ambient, derating linearly to zero at +175°C. Its glass package and axial lead design enable efficient conduction cooling in dense avionics layouts. The JANS1N6136AUS/TR sustains this rating under full radiation exposure and thermal cycling without parameter degradation.
Can JANS1N6136AUS/TR be used as a voltage reference in space applications?
Yes, the JANS1N6136AUS/TR is radiation-hardened to 100 krad(Si) TID and qualified for operation from –65°C to +175°C, making it suitable for voltage reference use in LEO and GEO satellite power systems. Its low voltage drift (<±2% post-irradiation) and long-term stability ensure the JANS1N6136AUS/TR remains within specification throughout multi-year missions without recalibration.
