Product details
Overview
JANTX1N4132-1/TR from Microsemi is a 500 mW, 82 V, ±5% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4132-1/TR datasheet, JANTX1N4132-1/TR pinout, JANTX1N4132-1/TR application, or JANTX1N4132-1/TR equivalent, key selection criteria include Zener voltage (82 V), test current (250 mA), dynamic impedance (800 Ω), max reverse leakage (0.01 µA at 65.6 V), and radiation-hardened construction per MicroNote 050.
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 temperature coefficient of +0.100 %/°C and low noise density (≤1 µV/√Hz below 6.8 V, scaling with voltage). Its metallurgical bond ensures stable breakdown characteristics under thermal cycling and mechanical stress.
Designed for operation in the reverse-biased breakdown region, JANTX1N4132-1/TR maintains regulation across wide current ranges (IZK to IZM = 62.4 mA) and temperatures (–65 °C to +175 °C), with junction-to-lead thermal resistance of 250 °C/W at 10 mm lead length - critical for high-reliability linear regulator and reference applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 82 V at 250 mA - defines precise regulation point for high-voltage reference circuits |
| Power Dissipation | 500 mW at 25 °C - sets maximum continuous DC power handling before derating begins at 50 °C |
| Zener Impedance ZZT | 800 Ω - determines output voltage stability under load current variation |
| Reverse Leakage IR | 0.01 µA at 65.6 V - ensures minimal standby current in high-impedance bias networks |
| Temp Coefficient αVZ | +0.100 %/°C - quantifies voltage drift over temperature; requires compensation in precision references |
| Noise Density | ≤1 µV/√Hz - enables use in low-noise analog references where spectral purity matters |
| Max Regulator Current IZM | 62.4 mA - defines upper limit of safe Zener current before exceeding PM(AV) |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-glass package with cathode indicated by 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 ground or lower-potential rail; establishes return path for Zener current |
| Cathode | Regulated output node | Banded end; carries regulated 82 V when reverse-biased; must be held positive relative to anode |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4132US | Same 82 V VZ, DO-213AA surface-mount package; no axial leads; 400 mW rating | Used where board space is constrained and reflow assembly required; lacks JANTX qualification | Select for commercial SMT designs needing footprint reduction; not suitable for mil-spec programs |
| JANS1N4132-1 | Identical electrical specs but qualified to JANS level (highest MIL-PRF-19500 screening tier) | Required for spaceflight and nuclear-hardened systems demanding full lot traceability and burn-in | Choose when radiation tolerance, extended temperature validation, and full JANS screening are mandatory |
Compared with JANTX1N4132-1/TR, 1N4132US trades axial-leaded reliability and JANTX qualification for SMT compatibility and smaller footprint, while JANS1N4132-1 adds rigorous screening and extended environmental testing - making it the only option for Class S space applications.

FAQ
What is the Zener voltage tolerance for JANTX1N4132-1/TR?
JANTX1N4132-1/TR has a nominal Zener voltage of 82 V with a standard tolerance of ±5%, as defined by JEDEC registration and verified per MIL-PRF-19500/435 screening. This tolerance applies at 25 °C with 250 mA test current and is maintained across the full JANTX qualification temperature range.
Is JANTX1N4132-1/TR RoHS compliant?
No, JANTX1N4132-1/TR is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4132-1e3); JANTX-level parts retain tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability under thermal cycling in military environments.
What is the maximum Zener current IZM for JANTX1N4132-1/TR?
The maximum Zener current IZM for JANTX1N4132-1/TR is 62.4 mA, derived from its 500 mW power rating and 82 V Zener voltage (IZM = PM(AV)/VZ). This value assumes thermal equilibrium at 25 °C and must be reduced per the linear derating curve above 50 °C ambient or lead temperature.
Does JANTX1N4132-1/TR have radiation hardness certification?
Yes, JANTX1N4132-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction provides proven resistance to total ionizing dose (TID), making it suitable for low-earth orbit and terrestrial nuclear instrumentation without additional shielding or qualification testing.
What package type does JANTX1N4132-1/TR use?
JANTX1N4132-1/TR uses the DO-35 (also designated DO-204AH) hermetically sealed axial-leaded glass package. It features tin-lead plated leads, cathode band marking, and mechanical dimensions conforming to MIL-PRF-19500/435 requirements - including body diameter 1.42–2.29 mm and overall length 3.56–5.08 mm.
