Product details
Overview
JANTXV1N4126C-1 from Microsemi is a 51 V, 500 mW axial-leaded glass Zener diode in DO-35 (DO-204AH) package, qualified to JANTXV level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 300 Ω dynamic impedance at 250 mA test current, and 7.5 mA maximum Zener current for precision voltage regulation in high-reliability analog power supplies.
For engineers reviewing the JANTXV1N4126C-1 datasheet, JANTXV1N4126C-1 pinout, JANTXV1N4126C-1 application, or JANTXV1N4126C-1 equivalent, key selection criteria include military-grade reliability qualification, low noise density (≤1 µV/√Hz), tight 2% voltage tolerance, thermal resistance of 250 °C/W junction-to-lead, and hermetic glass packaging for aerospace and defense power conditioning circuits.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with Zener voltage specified at 250 mA test current (IZT) and characterized over -65 °C to +175 °C junction temperature range. Its metallurgically bonded construction ensures stable regulation under thermal cycling and radiation exposure.
It exhibits a positive temperature coefficient of +0.100 %/°C above 50 V, enabling predictable drift compensation in temperature-stable references. Dynamic impedance (ZZT = 300 Ω) and low reverse leakage (IR ≤ 0.01 µA at VR = 38.8 V) support low-noise, high-precision biasing in instrumentation amplifiers and ADC reference circuits.
