Product details
Overview
JAN1N4100D-1/TR from Microsemi is a 7.5 V, 1% tolerance, 500 mW axial-leaded glass Zener diode in DO-35 (DO-204AH) package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4100D-1/TR datasheet, JAN1N4100D-1/TR pinout, JAN1N4100D-1/TR application, or JAN1N4100D-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - all critical for precision biasing, reference, and overvoltage protection design.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 7.5 V at 250 mA test current, exhibiting +0.065 %/°C temperature coefficient and 200 Ω dynamic impedance at IZT. Its metallurgically bonded construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for operation across –65 °C to +175 °C junction temperature range, it delivers ≤1.0 µA reverse leakage at VR = 5.7 V and maintains low noise density (1 µV/√Hz typical at lower voltages), making it suitable for analog reference circuits where stability and low-noise performance are essential.

FAQ
What is the Zener voltage tolerance of JAN1N4100D-1/TR?
JAN1N4100D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This corresponds to a 7.5 V nominal Zener voltage ranging from 7.425 V to 7.575 V at 250 mA test current and 25 °C, enabling high-accuracy reference applications without external trimming.
Is JAN1N4100D-1/TR qualified to military standards?
Yes, JAN1N4100D-1/TR is qualified to JAN level per MIL-PRF-19500/435, including screening for temperature cycling, mechanical shock, and hermeticity. It meets the requirements for use in high-reliability military and aerospace systems where component failure is not acceptable.
What is the maximum power dissipation of JAN1N4100D-1/TR?
JAN1N4100D-1/TR has a rated average power dissipation of 500 mW at 25 °C. This rating linearly derates to zero at 175 °C junction temperature, with a thermal resistance of 250 °C/W junction-to-lead (measured at 3/8 inch lead length), supporting robust thermal management in dense layouts.
Does JAN1N4100D-1/TR have low noise performance?
Yes, JAN1N4100D-1/TR exhibits low noise density - typically 1 µV/√Hz at lower Zener voltages - due to its metallurgically bonded structure and optimized junction design. This makes it suitable for precision analog circuits such as ADC references and low-noise amplifier biasing where added noise must be minimized.
