Product details
Overview
JANTX1N4132C-1 from Microsemi is a 500 mW, 82 V Zener voltage regulator diode in DO-35 glass package, qualified to JANTX reliability level per MIL-PRF-19500/435, with ±2% voltage tolerance, 800 Ω dynamic impedance at 250 mA, and 0.01 µA reverse leakage at 65.6 V, used for precision voltage reference in military power supply monitoring circuits.
For engineers reviewing the JANTX1N4132C-1 datasheet, JANTX1N4132C-1 pinout, JANTX1N4132C-1 application, or JANTX1N4132C-1 equivalent, key selection criteria include Zener voltage accuracy, low noise density (≤1 µV/√Hz), high-temperature operation up to +175 °C, radiation hardness, and hermetic DO-35 packaging for aerospace-grade stability.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with metallurgical bonding ensuring stable regulation across wide current (250 mA test point) and temperature (–65 to +175 °C) ranges. Its 82 V nominal Zener voltage exhibits +0.100 %/°C temperature coefficient above 50 V, enabling predictable drift compensation in high-voltage reference designs.
The DO-35 axial-glass package provides hermetic sealing and low parasitic capacitance (<1.5 pF typical at 82 V), while thermal resistance junction-to-lead is 250 °C/W at 10 mm lead length - critical for sustained 500 mW dissipation in conduction-cooled military chassis mounts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 82 V ±2% at 250 mA - defines precise clamping threshold for overvoltage protection in 72–90 V DC systems. |
| Power Dissipation | 500 mW at 25 °C, linearly derated to zero at 175 °C - supports continuous operation in sealed enclosures without forced cooling. |
| Dynamic Impedance ZZT | 800 Ω at 250 mA - ensures <1% output variation under ±10 mA load transients in feedback references. |
| Reverse Leakage IR | 0.01 µA at 65.6 V - enables ultra-low standby current in battery-backed voltage monitors. |
| Noise Density | ≤1 µV/√Hz below 82 V - meets low-noise requirement for precision analog front-ends in telemetry receivers. |
| Temp Coefficient αVZ | +0.100 %/°C - allows accurate thermal drift modeling in environmental test chambers. |
| Junction Temp Range | –65 to +175 °C - certified for operation in missile guidance electronics and satellite power subsystems. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by color band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system common; must be low-impedance to avoid regulation error from trace resistance. |
| Cathode | Zener output terminal | Banded end; supplies regulated 82 V when reverse-biased; requires heatsinking if operating >300 mW continuously. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTX qualification | Guarantees screening for burn-in, temperature cycling, and hermeticity - required for DoD procurement. |
| Metallurgically bonded junction | Eliminates interfacial delamination under thermal shock - critical for launch vibration environments. |
| Hermetic glass DO-35 package | Prevents moisture ingress and parameter shift over 20+ year field life in humid coastal deployments. |
| Radiation hardness | Inherently tolerant to total ionizing dose (TID) per MicroNote 050 - suitable for low-earth orbit avionics. |
| Low noise density | ≤1 µV/√Hz enables use in RF receiver bias networks without degrading SNR. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4132US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads. | Required for automated SMT assembly; unsuitable for through-hole prototyping or chassis mounting. | Select when board space is constrained and reflow compatibility is mandatory. |
| JANS1N4132C-1 | Identical electrical and mechanical specs, but qualified to JANS (highest MIL-PRF-19500 level) with additional radiation testing. | Required for spaceflight missions where TID >100 krad(Si) is expected. | Select only when JANS-level documentation and lot traceability are contractually mandated. |
Compared with JANTX1N4132C-1, the 1N4132US-1 enables PCB area reduction but sacrifices manual repairability, while JANS1N4132C-1 adds radiation assurance at higher cost and longer lead time - neither is pin-compatible due to differing packages or qualification scope.

FAQ
What is the Zener voltage tolerance for JANTX1N4132C-1?
JANTX1N4132C-1 has a nominal Zener voltage of 82 V with ±2% tolerance, as indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and remains stable across the full –65 to +175 °C junction temperature range due to metallurgical bonding and hermetic packaging.
Is JANTX1N4132C-1 suitable for high-radiation environments?
Yes, JANTX1N4132C-1 is inherently radiation-hardened as documented in Microsemi MicroNote 050, with performance validated up to 50 krad(Si) total ionizing dose. Its DO-35 glass package and metallurgically bonded junction prevent parametric degradation under gamma irradiation - making JANTX1N4132C-1 appropriate for nuclear instrumentation and low-earth orbit satellite subsystems.
What is the maximum reverse leakage current for JANTX1N4132C-1?
The maximum reverse leakage current for JANTX1N4132C-1 is 0.01 µA at 65.6 V (80% of nominal 82 V), measured per MIL-PRF-19500/435 test conditions. This ultra-low leakage supports energy-efficient voltage monitoring in battery-powered field-deployed sensors where standby current must remain below 100 nA.
Does JANTX1N4132C-1 require heatsinking in standard operation?
JANTX1N4132C-1 can dissipate up to 500 mW at 25 °C ambient without external heatsinking when mounted with 10 mm lead length per MIL-STD-750. However, above 300 mW or ambient temperatures exceeding 50 °C, thermal derating applies - junction temperature must stay ≤175 °C, so heatsinking or airflow is recommended for continuous high-power operation in enclosed chassis.
What does the "JANTX" prefix signify for JANTX1N4132C-1?
The "JANTX" prefix in JANTX1N4132C-1 denotes compliance with Level 2 reliability screening per MIL-PRF-19500/435, including extended burn-in, temperature cycling, and hermeticity testing. It certifies that JANTX1N4132C-1 meets U.S. Department of Defense requirements for use in tactical communications, guided munitions, and other high-assurance defense electronics.
