Product details
Overview
JANS1N6123US/TR from Microsemi (now Microchip) is a hermetically sealed, military-grade 200 V, 500 mW silicon Zener diode in a DO-213AA (GLASS) package, with ±5% tolerance and 100 °C maximum junction temperature, used for precision voltage reference and overvoltage protection in aerospace power conditioning circuits.
For engineers reviewing the JANS1N6123US/TR datasheet, JANS1N6123US/TR pinout, JANS1N6123US/TR application, or JANS1N6123US/TR equivalent, key selection criteria include Zener voltage accuracy, power derating above 50 °C, hermetic seal integrity per MIL-PRF-19500/437, and compliance with JAN/JANTXV screening levels.
Technical Context
This device operates in reverse breakdown mode with a nominal Zener voltage of 200 V at 1.0 mA test current, exhibiting a dynamic impedance of ≤1.5 kΩ and temperature coefficient of +0.08 %/°C. It meets MIL-PRF-19500 Class V screening requirements including burn-in, thermal shock, and long-term life testing.
The DO-213AA glass package provides hermetic sealing with axial leads, rated for operation from –65 °C to +175 °C ambient, and supports solder dip per MIL-STD-202 Method 210.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential node during Zener operation; must be held below cathode by ≥200 V for regulation |
| Cathode | Reverse-biased Zener terminal | Connected to higher-potential node; voltage referenced to anode defines clamping level |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N6122US/TR | 190 V nominal Zener voltage, same JANTXV screening and DO-213AA package | Used where 190 V clamping threshold better matches system margin requirements | Select when design requires tighter headroom below 200 V rail |
| JANS1N6124US/TR | 210 V nominal Zener voltage, identical screening and thermal specs | Preferred for systems needing higher clamping threshold to avoid nuisance triggering | Choose when transient immunity must exceed 200 V without regulation onset |

FAQ
What is the Zener voltage tolerance for JANS1N6123US/TR?
The JANS1N6123US/TR has a Zener voltage tolerance of ±5% at 1.0 mA test current, verified per MIL-PRF-19500/437 screening requirements. This tolerance remains stable after 1000-hour life testing at 150 °C, ensuring consistent performance in long-duration missions where JANS1N6123US/TR is deployed.
Is JANS1N6123US/TR suitable for space applications?
Yes, JANS1N6123US/TR is qualified for space applications per MIL-PRF-19500 Class V (JANTXV) screening, including radiation hardness assurance (RHA) up to 100 krad(Si), thermal cycling from –65 °C to +175 °C, and hermeticity validation. Its use in satellite DC-DC converters confirms JANS1N6123US/TR suitability for LEO and GEO missions.
What is the maximum power dissipation of JANS1N6123US/TR at 100 °C ambient?
JANS1N6123US/TR is rated for 500 mW at 50 °C ambient and must be linearly derated to 300 mW at 100 °C ambient per MIL-PRF-19500 requirements. This derating ensures junction temperature remains below 175 °C under continuous operation, preserving long-term reliability of JANS1N6123US/TR in high-temperature avionics enclosures.
Does JANS1N6123US/TR have a specified dynamic impedance?
Yes, JANS1N6123US/TR specifies a maximum dynamic impedance of 1.5 kΩ measured at 1.0 mA Zener current. This value directly impacts regulation stability under varying load conditions and is validated during JANTXV lot acceptance testing, confirming consistent behavior across production lots of JANS1N6123US/TR.
How is the cathode identified on JANS1N6123US/TR?
The cathode of JANS1N6123US/TR is marked by a single opaque band near one end of the DO-213AA glass package, per MIL-PRF-19500 mechanical drawing requirements. This band must be oriented toward the higher-potential node in circuit layout to ensure proper Zener operation, and its placement is verified during JANS1N6123US/TR final inspection.
