Product details
Overview
JAN1N4100-1/TR from Microsemi is a 500 mW, 7.5 V axial-leaded Zener diode in DO-35 (DO-204AH) glass package, qualified to JAN level per MIL-PRF-19500/435. It delivers ±5% Zener voltage tolerance, 250 mA test current, 200 Ω dynamic impedance at IZT, and operates across –65 °C to +175 °C for precision voltage regulation in high-reliability analog power supplies.
For engineers reviewing the JAN1N4100-1/TR datasheet, JAN1N4100-1/TR pinout, JAN1N4100-1/TR application, or JAN1N4100-1/TR equivalent, key selection criteria include its MIL-qualified reliability grade, low noise density (1 µV/√Hz), hermetic glass packaging, and thermal resistance of 250 °C/W junction-to-lead - critical for aerospace and defense power conditioning designs.
Technical Context
This Zener diode uses metallurgical bonding to ensure stable breakdown characteristics under thermal cycling and radiation exposure. Its 7.5 V nominal Zener voltage exhibits +0.065 %/°C temperature coefficient and maintains regulation over 5.7 mA to 40 mA operating current range.
The device is reverse-biased with cathode band indicating polarity and rated for 0.5 W average power dissipation, derating linearly from 500 mW at 25 °C to zero at 175 °C ambient. It achieves minimal capacitance (~42 pF) and non-sensitive ESD performance per MIL-STD-750 method 1020.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4100US-1 | Same electrical specs but in DO-213AA surface-mount package - no axial leads, smaller footprint | Used where board space is constrained and reflow soldering is preferred over through-hole mounting | Select when transitioning from through-hole to SMT assembly; requires PCB redesign due to different package and thermal path |
| JANTX1N4100-1 | Identical DO-35 package and electrical parameters, but qualified to JANTX level with additional screening tests | Required for programs mandating JANTX-level reliability documentation and lot traceability beyond JAN | Choose when system specification explicitly calls for JANTX qualification - not a drop-in replacement without compliance review |
Compared with JAN1N4100-1/TR, the 1N4100US-1 enables miniaturized layouts but sacrifices axial-lead mechanical robustness, while JANTX1N4100-1 adds screening overhead without electrical benefit - both require validation against the specific program's qualification and sourcing requirements.

FAQ
What is the Zener voltage tolerance for JAN1N4100-1/TR?
The JAN1N4100-1/TR has a nominal Zener voltage of 7.5 V with a standard tolerance of ±5%, as defined in the JEDEC-registered electrical characteristics table. This tolerance applies at 25 °C with the diode in thermal equilibrium and is verified per MIL-PRF-19500/435 screening requirements for JAN-level devices.
Is JAN1N4100-1/TR RoHS compliant?
No, JAN1N4100-1/TR is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4100-1e3); JAN-level parts use traditional tin-lead plating to meet MIL-STD-750 solderability requirements and are exempt from RoHS restrictions per defense procurement guidelines.
What does the "TR" suffix mean in JAN1N4100-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JAN1N4100-1/TR is supplied in reels with standardized orientation and spacing, supporting high-volume manufacturing while preserving JAN-level traceability and screening documentation for each reel lot.
How is the thermal performance of JAN1N4100-1/TR characterized?
JAN1N4100-1/TR has a junction-to-lead thermal resistance (RθJL) of 250 °C/W when mounted with 3/8″ (10 mm) lead length from body, and junction-to-ambient (RθJA) of 300 °C/W on FR4 board with specified copper pad geometry. Power must be linearly derated from 500 mW starting at 50 °C lead temperature, reaching zero at 175 °C.
Can JAN1N4100-1/TR be used in surface-mount designs?
No - JAN1N4100-1/TR is strictly a DO-35 axial-leaded through-hole device. For surface-mount equivalents, consider the 1N4100US-1 in DO-213AA package. Substituting JAN1N4100-1/TR into SMT footprints would require mechanical adaptation and invalidate MIL qualification due to altered thermal and mechanical stress profiles.
