Product details
Overview
JAN1N4132C-1/TR from Microsemi is a 500 mW, 82 V, ±2% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4132C-1/TR datasheet, JAN1N4132C-1/TR pinout, JAN1N4132C-1/TR application, or JAN1N4132C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), JANS-qualified thermal stability (–65 °C to +175 °C), and hermetic DO-35 packaging for radiation-hardened environments.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 82 V at 250 mA test current, exhibiting a positive temperature coefficient of +0.100 %/°C and dynamic impedance of 800 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for high-reliability DC voltage reference and overvoltage clamping, it delivers 40 µA maximum reverse leakage at VR = 65.6 V and supports linear derating from 500 mW at 25 °C to zero at 175 °C with RθJL = 250 °C/W (3/8″ lead length).
Key Specifications

| Power Dissipation | 500 mW at 25 °C - enables compact axial-leaded regulation without heatsinking in low-current bias networks. |
| Dynamic Impedance ZZT | 800 Ω at IZT = 250 mA - ensures stable regulation under varying load conditions in analog control circuits. |
| Noise Density | 1 µV/√Hz - minimizes voltage reference noise in precision instrumentation and ADC reference buffers. |
| Reverse Leakage IR | ≤40 µA at 65.6 V - guarantees low standby current in protection circuits and voltage monitors. |
| Temp Coefficient αVZ | +0.100 %/°C - enables predictable drift compensation in wide-temperature-range military avionics. |
| Junction Temp Range | –65 °C to +175 °C - supports operation in extreme environments including space-grade power conditioning modules. |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded glass package with cathode band marking; 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 ground or lower-potential rail; defines Zener conduction direction when cathode is biased positive. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4132US-1 | Same 82 V ±2% spec, but in DO-213AA surface-mount package; no axial leads. | Used where board space constraints prohibit through-hole mounting; requires reflow-compatible layout. | Select when automated SMT assembly is required and thermal path to PCB copper is optimized. |
| JANTXV1N4132C-1 | Identical electrical specs, but qualified to JANTXV level with enhanced screening and tighter parametric limits. | Required for programs mandating JANTXV reliability assurance (e.g., DoD Class H systems). | Select when full JANTXV qualification documentation and extended life test data are contractually required. |
Compared with JAN1N4132C-1/TR, the 1N4132US-1 offers identical regulation performance in a space-saving SMT form factor, while JANTXV1N4132C-1 adds higher-screening rigor for mission-critical deployments-neither is pin-compatible due to differing packages or qualification scope.

FAQ
What is the Zener voltage tolerance of JAN1N4132C-1/TR?
JAN1N4132C-1/TR has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its nomenclature. This corresponds to a guaranteed 80.36 V to 83.64 V range at 250 mA test current and 25 °C ambient, verified per MIL-PRF-19500/435 screening requirements.
Is JAN1N4132C-1/TR RoHS compliant?
No, JAN1N4132C-1/TR is not RoHS compliant. The "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions. JAN-level parts like JAN1N4132C-1/TR use traditional tin-lead plating per MIL-STD-750 and are exempt from RoHS restrictions under defense procurement rules.
What does the "TR" suffix mean in JAN1N4132C-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JAN1N4132C-1/TR is supplied in reels containing standard quantities, with part marking and polarity band preserved for traceability and correct orientation during placement.
How is the thermal performance of JAN1N4132C-1/TR characterized?
JAN1N4132C-1/TR has RθJL = 250 °C/W (junction-to-lead, 3/8″ lead length) and RθJA = 300 °C/W (junction-to-ambient on FR4). Power must be linearly derated from 500 mW at 25 °C to zero at 175 °C, with full rating maintained only when leads are properly heat-sunk per MIL-PRF-19500/435 mounting guidelines.
Can JAN1N4132C-1/TR replace commercial 1N4132-1 in existing designs?
JAN1N4132C-1/TR shares identical electrical specs with commercial 1N4132-1 but adds JAN-level screening, extended temperature range (–65 °C to +175 °C), and hermetic DO-35 construction. It can replace 1N4132-1 in high-reliability upgrades, though qualification retesting may be required per program-specific configuration control procedures.
