Product details
Overview
JANTX1N4626D-1/TR from Microsemi is a 5.6 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 axial package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power supplies.
For engineers reviewing the JANTX1N4626D-1/TR datasheet, JANTX1N4626D-1/TR pinout, JANTX1N4626D-1/TR application, or JANTX1N4626D-1/TR equivalent, key selection factors include its 1% Zener voltage tolerance, 5.6 V nominal regulation at 250 mA test current, low 1400 Ω dynamic impedance, and radiation-hardened hermetic DO-35 construction suitable for harsh-environment analog reference and bias circuits.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 5.6 V at IZT = 250 mA, exhibiting a temperature coefficient of –0.020/+0.040 %/°C and maximum noise density of 4 µV/√Hz. Its metallurgical bond ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Rated for 500 mW average power dissipation at 25 °C with linear derating to zero at 175 °C, it supports reverse leakage current ≤5.0 µA at VR = 4.0 V and maintains dynamic impedance ≤1400 Ω at 10% AC modulation superimposed on IZT - critical for low-noise analog references.
