Product details
Overview
JAN1N4119C-1/TR from Microsemi is a 28.0 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power conditioning and precision reference circuits.
For engineers reviewing the JAN1N4119C-1/TR datasheet, JAN1N4119C-1/TR pinout, JAN1N4119C-1/TR application, or JAN1N4119C-1/TR equivalent, key selection criteria include Zener voltage tolerance (2%), dynamic impedance (200 Ω @ 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.095 %/°C), and JANS-qualified thermal stability up to +175 °C.
Technical Context
This Zener diode operates in reverse breakdown with cathode-banded polarity, delivering stable 28.0 V regulation across 1 mA to 40 mA current range while maintaining low noise density (1 µV/√Hz) and tight 2% voltage tolerance. Its metallurgical bond construction ensures robust junction integrity under thermal cycling and radiation exposure.
The device exhibits a positive temperature coefficient of +0.095 %/°C and dynamic impedance of 200 Ω at 250 mA test current, enabling predictable voltage drift and low AC impedance in feedback loops. It is rated for 500 mW average power dissipation with linear derating above +50 °C ambient.
