Product details
Overview
JANS1N4132D-1/TR from Microsemi is a 82 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications, with max noise density of 1 µV/√Hz and dynamic impedance of 800 Ω at 250 mA test current.
For engineers reviewing the JANS1N4132D-1/TR datasheet, JANS1N4132D-1/TR pinout, JANS1N4132D-1/TR application, or JANS1N4132D-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient (+0.100 %/°C), reverse leakage (≤0.01 µA @ 65.6 V), power derating behavior, and JANS-level qualification evidence - critical for radiation-hardened, low-noise voltage reference design.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with Zener voltage specified at 250 mA test current (IZT) and thermal equilibrium at 25 °C. Its metallurgical bond construction ensures stable junction characteristics under thermal cycling and mechanical stress.
The JANS qualification confirms compliance with MIL-PRF-19500/435 for screening, testing, and lot traceability across temperature extremes (–65 °C to +175 °C), while its 1% tolerance (denoted by "D" in part nomenclature) and +0.100 %/°C temperature coefficient enable predictable regulation in wide-temperature military systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 82 V ±1% at 250 mA - enables precise 82 V reference in regulated power supplies and overvoltage protection circuits. |
| Power Dissipation | 500 mW at 25 °C, linearly derated to zero at 175 °C - defines maximum continuous power handling before thermal runaway. |
| Dynamic Impedance ZZT | 800 Ω at IZT = 250 mA - determines output voltage stability under load current variation; lower values improve regulation. |
| Reverse Leakage IR | ≤0.01 µA at VR = 65.6 V - ensures minimal parasitic current in high-impedance bias networks and sensing circuits. |
| Noise Density ND | 1 µV/√Hz at IZT = 250 mA - supports ultra-low-noise voltage references in precision analog front-ends and instrumentation. |
| Temp. Coefficient αVZ | +0.100 %/°C - quantifies voltage drift with temperature; critical for accuracy in unregulated ambient environments. |
| Junction Temp. Range | –65 °C to +175 °C - validated operational envelope for space, avionics, and nuclear instrumentation systems. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed 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 lowest potential point; establishes return path for Zener current. |
| Cathode (banded end) | Regulated output node | Provides stable 82 V output when reverse-biased; must be held positive relative to anode for regulation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4132D-1 | Same 82 V, 1%, DO-35, but qualified only to JANTXV level (not JANS); lacks full MIL-PRF-19500/435 JANS screening. | Approved for high-reliability ground systems but not flight-qualified; unsuitable for space or critical avionics. | Select when JANS-level radiation assurance and lot traceability are not required. |
| 1N4132UR-1 | Same electrical specs, but in DO-213AA surface-mount package; no axial leads; RoHS-compliant plating only. | Designed for automated SMT assembly; incompatible with through-hole PCB layouts or manual repair workflows. | Select for compact, high-density PCBs where axial mounting is impractical. |
Compared with JANS1N4132D-1/TR, JANTXV1N4132D-1 offers identical regulation performance but reduced qualification rigor, while 1N4132UR-1 provides identical electrical behavior in a surface-mount form factor - enabling layout flexibility without compromising reference accuracy or noise performance.

FAQ
What is the Zener voltage tolerance of JANS1N4132D-1/TR?
The "D" suffix in JANS1N4132D-1/TR denotes a ±1% Zener voltage tolerance at 250 mA test current, verified per MIL-PRF-19500/435 screening and documented in the T4-LDS-0245-2 datasheet. This tight tolerance eliminates post-production calibration in precision reference designs and ensures consistent performance across temperature and lifetime.
Is JANS1N4132D-1/TR radiation hardened?
Yes, JANS1N4132D-1/TR is inherently radiation tolerant as confirmed in Microsemi MicroNote 050. Its metallurgically bonded structure and glass DO-35 package provide natural resistance to total ionizing dose (TID) and displacement damage, making it suitable for low-dose-rate space and nuclear instrumentation applications without additional hardening.
What does the "TR" suffix mean in JANS1N4132D-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANS1N4132D-1/TR is supplied in reels for high-volume manufacturing, with full JANS-level traceability maintained for every unit - unlike commercial "e3" variants which lack military qualification.
What is the maximum reverse leakage current for JANS1N4132D-1/TR?
JANS1N4132D-1/TR has a maximum reverse leakage current (IR) of 0.01 µA at VR = 65.6 V, measured per MIL-PRF-19500/435 test conditions. This ultra-low leakage preserves accuracy in high-impedance bias networks and ensures minimal error contribution in precision voltage divider topologies.
Can JANS1N4132D-1/TR operate at elevated temperatures?
Yes, JANS1N4132D-1/TR is rated for junction temperatures from –65 °C to +175 °C and features linear power derating from 500 mW at 25 °C to zero at 175 °C. Its DO-35 package achieves RθJL = 250 °C/W with 10 mm lead length, supporting reliable operation in conduction-cooled avionics and radar enclosures.
