Product details
Overview
JANTXV1N4133C-1 from Microsemi is a 500 mW, 87 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 JANTXV1N4133C-1 datasheet, JANTXV1N4133C-1 pinout, JANTXV1N4133C-1 application, or JANTXV1N4133C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), radiation hardness, and hermetic DO-35 packaging for harsh-environment operation.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 87 V at 250 mA test current, exhibiting a temperature coefficient of +0.100 %/°C and dynamic impedance of 1000 Ω at IZT. Its metallurgical bond construction ensures stable regulation across wide current and temperature ranges.
Rated for 500 mW average power dissipation at 25 °C with linear derating to zero at 175 °C, it supports reverse leakage ≤0.01 µA at 69.6 V and maintains low capacitance (typical <1.5 pF) per Figure 3 - critical for noise-sensitive reference and biasing circuits.
