Product details
Overview
JANS1N4132-1/TR from Microsemi is a 500 mW, 82 V Zener voltage regulator diode in DO-35 glass package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers ±5% Zener tolerance, 800 Ω dynamic impedance at 250 mA test current, and operates across –65 °C to +175 °C junction temperature range.
For engineers reviewing the JANS1N4132-1/TR datasheet, JANS1N4132-1/TR pinout, JANS1N4132-1/TR application, or JANS1N4132-1/TR equivalent, key selection criteria include radiation-hardened performance, low noise density (≤1 μV/√Hz), hermetic glass sealing, and compliance with military-level thermal derating and ESD immunity requirements.
Technical Context
This device functions as a precision shunt voltage reference in regulated power supplies and voltage-clamping circuits where long-term stability under extreme environmental stress is mandatory. Its metallurgically bonded construction ensures robustness against thermal cycling and mechanical shock, while its low capacitance (<1.5 pF at 82 V) supports high-frequency noise suppression.
The JANS1N4132-1/TR exhibits a positive temperature coefficient of +0.100 %/°C, enabling predictable voltage drift over wide temperature excursions. Its maximum reverse leakage current is 0.01 µA at 65.6 V, and it maintains stable regulation down to 250 mA Zener test current with 40 mW maximum noise density at higher voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 82 V ±5% at 250 mA - defines precise clamping threshold for overvoltage protection in avionics power rails. |
| Power Dissipation | 500 mW @ 25 °C, linearly derated to zero at 175 °C - enables operation in high-temperature chassis without forced cooling. |
| Dynamic Impedance ZZT | 800 Ω max at 250 mA - ensures minimal output voltage variation under load transients in reference circuits. |
| Reverse Leakage IR | 0.01 µA max at 65.6 V - guarantees negligible standby current in battery-backed systems. |
| Noise Density | ≤1 µV/√Hz below 6.8 V; not specified above - confirms ultra-low broadband noise for analog signal conditioning references. |
| Temp Coefficient αVZ | +0.100 %/°C - allows accurate prediction of voltage drift across –65 °C to +175 °C operational envelope. |
| Junction Temp Range | –65 °C to +175 °C - validated for use in satellite payload electronics and missile guidance subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4132-1 | Same electrical specs but qualified only to JANTXV level; lower screening rigor than JANS. | Limited to non-spaceflight military platforms where full JANS testing is not mandated. | Select when cost sensitivity outweighs need for full space-qualified screening. |
| 1N4132US-1 | Same Zener voltage and DO-35 package but commercial-grade; no MIL-PRF-19500 qualification. | Restricted to ground-based industrial test equipment with benign thermal/EMI environment. | Choose only for prototyping or non-critical subsystems lacking radiation or reliability requirements. |
Compared with JANS1N4132-1/TR, JANTXV1N4132-1 offers identical regulation performance but reduced lifetime validation for extended missions, while 1N4132US-1 lacks hermeticity and radiation tolerance-making both unsuitable for flight hardware unless explicitly approved for lower-tier applications.

FAQ
What is the Zener voltage tolerance for JANS1N4132-1/TR?
JANS1N4132-1/TR has a nominal Zener voltage of 82 V with a standard tolerance of ±5%, as defined in the JEDEC-registered electrical characteristics table. This tolerance applies at 25 °C with the diode in thermal equilibrium and is verified during JANS-level qualification testing per MIL-PRF-19500/435.
Is JANS1N4132-1/TR RoHS compliant?
No, JANS1N4132-1/TR is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4132-1e3); JANS-level devices use traditional tin-lead plating to meet MIL-STD-750 solderability requirements and maintain hermetic seal integrity under thermal cycling stress.
What is the maximum reverse leakage current for JANS1N4132-1/TR?
The maximum reverse leakage current for JANS1N4132-1/TR is 0.01 µA at a reverse voltage of 65.6 V (80% of nominal VZ). This value is measured at 25 °C and confirmed during JANS-level screening to ensure low standby power consumption in high-impedance bias networks.
Can JANS1N4132-1/TR be used in surface-mount designs?
No, JANS1N4132-1/TR is packaged exclusively in the axial-leaded DO-35 (DO-204AH) glass case. Surface-mount alternatives such as 1N4132UR-1 (DO-213AA) exist but are not JANS-qualified and lack the same radiation hardness and hermeticity validation as JANS1N4132-1/TR.
What is the thermal resistance junction-to-lead for JANS1N4132-1/TR?
JANS1N4132-1/TR has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when mounted with 3/8 inch (10 mm) lead length from body. This parameter governs heat transfer efficiency in chassis-mounted configurations and informs derating calculations for sustained power dissipation in conduction-cooled assemblies.
