Product details
Overview
JANTXV1N4132C-1/TR from Microsemi is a 500 mW, 82 V, ±2% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4132C-1/TR datasheet, JANTXV1N4132C-1/TR pinout, JANTXV1N4132C-1/TR application, or JANTXV1N4132C-1/TR equivalent, key selection factors include its 82 V nominal Zener voltage at 250 mA test current, 800 Ω maximum dynamic impedance, 0.01 µA maximum reverse leakage at 65.6 V, and +0.100 %/°C temperature coefficient - critical for precision reference stability under thermal stress.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures low noise density (≤1 µV/√Hz below 6.8 V) and inherent radiation hardness per Microsemi MicroNote 050.
It delivers stable regulation across wide current ranges (IZK to IZM = 40 mA max) and temperature extremes (–65 °C to +175 °C junction), with thermal resistance of 250 °C/W junction-to-lead (3/8″ lead length) and linear power derating from 500 mW at 25 °C to zero at 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 82 V at 250 mA test current - sets precise reference point for regulated output in feedback loops. |
| Zener Tolerance | ±2% - tighter than standard 5% parts, enabling higher accuracy in calibration circuits. |
| Max Dynamic Impedance | 800 Ω at 250 mA - determines load regulation error under varying current draw. |
| Max Reverse Leakage | 0.01 µA at 65.6 V - ensures minimal quiescent current in standby or low-power modes. |
| Temp Coefficient αVZ | +0.100 %/°C - quantifies voltage drift per degree, critical for thermal compensation design. |
| Power Dissipation | 500 mW at 25 °C, derated linearly to zero at 175 °C - defines safe operating envelope on PCB. |
| Noise Density | ≤1 µV/√Hz - enables use in low-noise analog references where signal integrity is paramount. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4132US-1 | Same 82 V, ±2%, DO-213AA surface-mount package; no axial leads. | Used where board space is constrained and reflow assembly is required instead of through-hole mounting. | Select when automated SMT production and smaller footprint outweigh axial-lead serviceability needs. |
| JANS1N4132C-1 | Identical electrical specs but qualified to JANS (highest MIL-PRF-19500 level) with extended screening. | Required for mission-critical space hardware where single-event burnout (SEB) immunity and lot traceability are mandatory. | Choose only when JANS-level documentation, radiation test reports, and full lot traceability are contractually required. |
Compared with JANTXV1N4132C-1/TR, the 1N4132US-1 offers identical regulation performance in a compact surface-mount form factor ideal for high-density layouts, while JANS1N4132C-1 adds enhanced screening and radiation assurance for deep-space missions - neither is pin-compatible due to differing packages or qualification scope.

FAQ
What is the Zener voltage tolerance of JANTXV1N4132C-1/TR?
JANTXV1N4132C-1/TR has a nominal Zener voltage of 82 V with a ±2% tolerance, meaning its actual regulation voltage falls between 80.36 V and 83.64 V when measured at 250 mA test current and 25 °C ambient. This tighter tolerance supports higher-accuracy reference designs compared to standard ±5% Zeners.
Is JANTXV1N4132C-1/TR suitable for high-temperature operation?
Yes, JANTXV1N4132C-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 metallurgical bond and hermetic DO-35 package ensure stable operation in engine bay or avionics bay environments exceeding 125 °C ambient.
Does JANTXV1N4132C-1/TR meet RoHS requirements?
No, JANTXV1N4132C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (suffix e3) are available only for commercial-grade parts; JANTXV-level devices retain tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
What is the maximum reverse leakage current for JANTXV1N4132C-1/TR?
JANTXV1N4132C-1/TR specifies a maximum reverse leakage current (IR) of 0.01 µA at VR = 65.6 V (80% of nominal Zener voltage). This ultra-low leakage minimizes standby power loss and maintains regulation accuracy in high-impedance bias networks.
How is polarity marked on JANTXV1N4132C-1/TR?
JANTXV1N4132C-1/TR uses a cathode band - a distinct colored ring near one end of the DO-35 glass body - to indicate the cathode terminal. The diode must be installed with the banded end connected to the higher-potential node to operate in Zener breakdown mode; reverse orientation causes forward conduction at ~1.1 V.
