Product details
Overview
JANTXV1N4124D-1 from Microsemi is a 500 mW, 43 V, 1% tolerance Zener diode in DO-35 glass package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4124D-1 datasheet, JANTXV1N4124D-1 pinout, JANTXV1N4124D-1 application, or JANTXV1N4124D-1 equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - critical for precision reference and radiation-hardened designs.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 43.0 V at 250 mA test current, ±1% tolerance (denoted by "D" suffix), and a positive temperature coefficient of +0.095 %/°C. Its metallurgically bonded construction ensures stable regulation across -65 °C to +175 °C junction temperature range.
It exhibits 250 Ω maximum dynamic impedance (ZZT) at IZT = 250 mA, 0.01 µA maximum reverse leakage at VR = 32.7 V, and 8.9 mA maximum Zener current (IZM) under rated 500 mW dissipation - enabling use in low-noise, high-stability analog references where thermal drift and impedance matching matter.
