Product details
Overview
JAN1N4116D-1/TR from Microsemi is a 24.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power conditioning circuits.
For engineers reviewing the JAN1N4116D-1/TR datasheet, JAN1N4116D-1/TR pinout, JAN1N4116D-1/TR application, or JAN1N4116D-1/TR equivalent, key selection criteria include its 24.0 V nominal Zener voltage at 250 mA test current, 150 Ω dynamic impedance, 0.01 µA maximum reverse leakage at 18.3 V, ±0.090 %/°C temperature coefficient, and hermetically sealed DO-35 package rated for -65 °C to +175 °C operation.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable reference voltage across wide current (250 mA IZT) and temperature (-65 °C to +175 °C) ranges. Its internal metallurgical bond ensures low noise density (1 µV/√Hz typical at low voltages) and radiation hardness per Microsemi MicroNote 050.
Designed for precision voltage regulation in analog signal chains and power supply feedback loops, it delivers 24.0 V with 1% tolerance (denoted by "D" in part nomenclature), 150 Ω Zener impedance at 250 mA, and minimal capacitance - critical for low-noise instrumentation and high-stability reference applications.

FAQ
What is the Zener voltage and tolerance of JAN1N4116D-1/TR?
JAN1N4116D-1/TR has a nominal Zener voltage of 24.0 V at 250 mA test current with ±1% tolerance, as confirmed by Microsemi's T4-LDS-0245-2 datasheet. This tight tolerance is denoted by the "D" suffix and enables direct use in precision reference circuits without calibration or trimming.
Is JAN1N4116D-1/TR qualified to military specifications?
Yes, JAN1N4116D-1/TR is qualified to JAN level per MIL-PRF-19500/435, including full screening for high-reliability applications. The "JAN" prefix indicates compliance with baseline military screening requirements, and the device is hermetically sealed in a DO-35 glass package meeting environmental and life-test standards.
What is the maximum power dissipation and derating behavior of JAN1N4116D-1/TR?
JAN1N4116D-1/TR has a rated average power dissipation of 500 mW at 25 °C, linearly derated to zero at 175 °C. Derating begins at 50 °C for lead temperature or 25 °C for ambient on a typical PCB, per Figure 2 in the official datasheet - ensuring safe operation across extended thermal ranges.
Does JAN1N4116D-1/TR have low noise characteristics suitable for precision analog circuits?
Yes, JAN1N4116D-1/TR exhibits low noise density - 1 µV/√Hz typical at its 24 V operating point - due to metallurgical bond construction. This is explicitly documented in the "FEATURES" section and Figure 1 of the Microsemi datasheet, making it suitable for high-resolution ADC references and low-phase-noise RF biasing.
What does the "TR" suffix indicate in JAN1N4116D-1/TR?
The "TR" suffix in JAN1N4116D-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format is standard for volume production and is explicitly noted in the "MECHANICAL and PACKAGING" section of the Microsemi datasheet.
