Product details
Overview
JAN1N4132D-1 from Microsemi is a 500 mW, 82 V, 1% 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 JAN1N4132D-1 datasheet, JAN1N4132D-1 pinout, JAN1N4132D-1 application, or JAN1N4132D-1 equivalent, key selection criteria include Zener voltage tolerance (±1%), noise density (1 µV/√Hz), dynamic impedance (800 Ω), temperature coefficient (+0.100 %/°C), and JANS-qualified reliability grading.
Technical Context
This axial-leaded Zener diode operates in reverse breakdown with cathode band indicating polarity, requiring banded end positive relative to anode for regulation. Its metallurgical bond ensures stable junction behavior under thermal cycling and radiation exposure.
It delivers precise 82 V regulation at 250 mA test current (IZT), with low leakage (≤0.01 µA at 65.6 V), minimal capacitance (typ. <1.5 pF), and inherent radiation hardness per Microsemi MicroNote 050 - critical for space-grade analog references.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JAN1N4132C-1 | Same 82 V nominal, but ±2% tolerance instead of ±1% | Acceptable where tighter voltage accuracy is not required | Select when cost sensitivity outweighs need for 1% regulation precision |
| JANS1N4132D-1 | Identical electrical specs, but qualified to JANS (space-level) screening vs. JAN (military-level) | Required for flight-critical subsystems in spacecraft | Select only when full JANS radiation and reliability testing is mandated |
Compared with JAN1N4132D-1, JAN1N4132C-1 trades 1% tolerance for lower procurement cost, while JANS1N4132D-1 adds radiation hardness validation and extended screening - both retain identical DO-35 packaging, thermal resistance, and noise performance.

FAQ
What is the Zener voltage tolerance of JAN1N4132D-1?
JAN1N4132D-1 has a nominal Zener voltage of 82.0 V with a tolerance of ±1%, as indicated by the "D" suffix in its nomenclature. This tight tolerance is verified per MIL-PRF-19500/435 screening and supports high-accuracy voltage reference designs where deviation beyond ±0.82 V is unacceptable.
Is JAN1N4132D-1 RoHS compliant?
No, JAN1N4132D-1 is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4132D-1e3); JAN-level parts like JAN1N4132D-1 use traditional tin-lead plating per MIL-STD-750 and are exempt from RoHS requirements due to their military qualification status.
What is the maximum Zener test current (IZT) for JAN1N4132D-1?
The maximum Zener test current IZT for JAN1N4132D-1 is 250 mA, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This current establishes the 82.0 V regulation point and is used to measure dynamic impedance (ZZT ≤ 800 Ω) and noise density (ND = 1 µV/√Hz).
How does the temperature coefficient affect JAN1N4132D-1 performance?
JAN1N4132D-1 has a temperature coefficient αVZ of +0.100 %/°C, meaning its Zener voltage increases by approximately 82 mV per °C rise in junction temperature. This predictable positive drift allows designers to compensate using complementary components in high-stability reference circuits.
Can JAN1N4132D-1 be used in surface-mount designs?
No, JAN1N4132D-1 is packaged exclusively in the axial-leaded DO-35 (DO-204AH) through-hole format. Surface-mount alternatives such as 1N4132UR-1 (DO-213AA) or 1PMT4132 (DO-216) exist but are distinct orderable parts - JAN1N4132D-1 itself requires through-hole PCB mounting.
