Product details
Overview
JANTXV1N4132C-1 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 datasheet, JANTXV1N4132C-1 pinout, JANTXV1N4132C-1 application, or JANTXV1N4132C-1 equivalent, key selection factors include its 82 V nominal Zener voltage at 250 mA test current, 800 Ω dynamic impedance, 0.01 µA maximum reverse leakage at 65.6 V, radiation-hardened construction, and hermetically sealed axial-leaded package.
Technical Context
This device operates as a precision shunt voltage regulator with a specified Zener voltage of 82 V at IZT = 250 mA, exhibiting a temperature coefficient of +0.100 %/°C and low noise density (≤1 µV/√Hz below 6.8 V, rising to 1 µV/√Hz at 82 V per family trend). Its metallurgical bond ensures stable breakdown characteristics under thermal cycling.
Designed for operation in the reverse-biased breakdown region, it maintains regulation across wide current ranges (up to 62.4 mA max Zener current) and temperatures (–65 °C to +175 °C), with thermal resistance junction-to-lead of 250 °C/W at 10 mm lead length - critical for high-reliability board-level thermal management.
Key Specifications

FAQ
What is the Zener voltage tolerance of JANTXV1N4132C-1?
JANTXV1N4132C-1 has a nominal Zener voltage of 82 V with a tolerance of ±2%, denoted by the "C" suffix in the part number per Microsemi's nomenclature. This tighter tolerance enables higher-accuracy regulation compared to standard ±5% variants like JANTXV1N4132-1, and is verified per MIL-PRF-19500/435 screening requirements.
Is JANTXV1N4132C-1 radiation hardened?
Yes, JANTXV1N4132C-1 is inherently radiation hard due to its metallurgically bonded structure and hermetic DO-35 package, as documented in Microsemi MicroNote 050. It exhibits robust performance under total ionizing dose (TID) exposure, making it suitable for space and nuclear environments without requiring additional shielding or derating.
What is the maximum Zener current for JANTXV1N4132C-1?
The maximum Zener current (IZM) for JANTXV1N4132C-1 is 62.4 mA, derived from its 500 mW power rating and 82 V Zener voltage (P = V × I). This value is specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1 and assumes operation at 25 °C with proper thermal management.
Does JANTXV1N4132C-1 have a RoHS-compliant version?
No - JANTXV1N4132C-1 is a military-qualified part with tin-lead plating per MIL-STD-750, and RoHS compliance (e3 suffix) is only available on commercial-grade versions such as 1N4132C-1e3. The JANTXV level requires traditional solderability and thermal performance characteristics incompatible with lead-free finishes.
What is the thermal resistance junction-to-lead for JANTXV1N4132C-1?
JANTXV1N4132C-1 has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when measured with 10 mm (3/8 inch) lead length from the package body, as specified in the Maximum Ratings table on page 1 of T4-LDS-0245-2 Rev. 1. This value guides heatsinking and PCB copper area design for sustained power dissipation.
