Product details
Overview
JANS1N6105US/TR from Microsemi (now Microchip) is a hermetically sealed, surface-mount silicon Zener diode rated for 56 V nominal breakdown voltage, 500 mW power dissipation, and ±5% voltage tolerance, designed for precision voltage regulation and transient overvoltage protection in aerospace and military-grade power supply circuits.
For engineers reviewing the JANS1N6105US/TR datasheet, JANS1N6105US/TR pinout, JANS1N6105US/TR application, or JANS1N6105US/TR equivalent, key selection criteria include Zener voltage accuracy, low dynamic impedance, high reliability under thermal cycling, and compliance with MIL-PRF-19500/507 requirements.
Technical Context
This device operates as a two-terminal voltage reference diode with sharp reverse breakdown characteristics. It meets MIL-PRF-19500/507 Class H specifications for high-reliability applications and is qualified for operation across –65 °C to +175 °C ambient temperature range.
The JANS1N6105US/TR features a hermetic glass-passivated junction and is tested per MIL-STD-883 methods including steady-state life, thermal shock, and burn-in. Its Zener voltage is specified at 56 V ±5% with a maximum Zener impedance of 150 Ω at 1 mA test current.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6105US | Same Zener voltage and package, but Class V (not Class H); lower screening level and no burn-in | Suitable for non-critical defense subsystems where full Class H is not mandated | Select JANTX1N6105US only when MIL-PRF-19500/507 Class H is not required by program spec |
| 1N6105US/TR | Commercial version; same electrical specs but no MIL qualification or hermetic seal | Applicable in industrial test equipment or ground-support units with controlled environments | Choose 1N6105US/TR for cost-sensitive, non-flight applications with relaxed reliability requirements |
Compared with JANS1N6105US/TR, JANTX1N6105US offers reduced screening rigor and no burn-in, while 1N6105US/TR lacks hermeticity and MIL qualification-both require revalidation if substituted into Class H-requiring designs.

FAQ
What is the Zener voltage tolerance for JANS1N6105US/TR?
The JANS1N6105US/TR has a Zener voltage tolerance of ±5% at 56 V, meaning its actual breakdown voltage falls between 53.2 V and 58.8 V when measured at the specified test current of 1 mA. This tolerance is guaranteed per MIL-PRF-19500/507 Class H screening and applies across the full operating temperature range of –65 °C to +175 °C. The JANS1N6105US/TR maintains this specification without additional calibration or trimming.
Is JANS1N6105US/TR hermetically sealed?
Yes, the JANS1N6105US/TR uses a hermetically sealed ceramic US package with glass-passivated junction, meeting MIL-PRF-19500/507 requirements for moisture resistance and long-term parameter stability. This seal prevents internal corrosion and parametric drift under high humidity, thermal cycling, or vacuum conditions-critical for the JANS1N6105US/TR's use in space and airborne platforms.
What is the maximum power dissipation rating for JANS1N6105US/TR?
The JANS1N6105US/TR is rated for a maximum power dissipation of 500 mW under specified thermal conditions. This rating assumes proper PCB thermal design with adequate copper area and is valid across its full operating temperature range. Derating is required above +75 °C ambient, per the device's thermal resistance curve in the official Microchip datasheet for JANS1N6105US/TR.
Does JANS1N6105US/TR meet MIL-PRF-19500/507 Class H requirements?
Yes, the JANS1N6105US/TR is fully qualified to MIL-PRF-19500/507 Class H, including all required tests: steady-state life, thermal shock, burn-in, and lot acceptance testing. Each JANS1N6105US/TR device carries full traceability documentation and is screened to ensure performance consistency in high-reliability applications such as flight-critical avionics and strategic defense systems.
What is the Zener impedance of JANS1N6105US/TR at 1 mA test current?
The JANS1N6105US/TR exhibits a maximum Zener impedance (ZZT) of 150 Ω when measured at a test current of 1 mA. This low impedance value ensures minimal voltage deviation under small load variations, making the JANS1N6105US/TR suitable for precision reference and clamping functions where regulation stability is essential.
