Product details
Overview
JAN1N4100C-1/TR from Microsemi is a 500 mW, 7.5 V Zener voltage regulator diode in DO-35 (DO-204AH) axial-glass package, qualified to JAN reliability level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 250 mA test current, and 200 Ω dynamic impedance at IZT - used for precision voltage reference and regulation in military-grade power supply feedback loops.
For engineers reviewing the JAN1N4100C-1/TR datasheet, JAN1N4100C-1/TR pinout, JAN1N4100C-1/TR application, or JAN1N4100C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), JANTX-level qualification, thermal resistance (250 °C/W junction-to-lead), and hermetic glass packaging for high-reliability analog and aerospace systems.
Technical Context
This device operates as a reverse-biased Zener regulator with metallurgically bonded construction for stable breakdown characteristics across temperature. It delivers 7.5 V regulation at 250 mA test current with ±2% tolerance and exhibits +0.065 %/°C temperature coefficient - enabling predictable drift compensation in analog references.
Its 200 Ω dynamic impedance at IZT and 1 µV/√Hz noise density (measured 1–3 kHz) support low-noise voltage referencing in precision instrumentation. The DO-35 package provides hermetic sealing and meets MIL-STD-750 solderability and ESD immunity requirements.

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 7.5 V, ±2%, DO-213AA surface-mount package; no axial leads; RθJA = 400 °C/W vs. 250 °C/W for JAN1N4100C-1/TR. | Used where board space is constrained and reflow assembly required; unsuitable for through-hole or high-power conduction cooling. | Select when automated SMT placement is mandatory and thermal derating can accommodate higher junction rise. |
| JANTX1N4100C-1 | Identical electrical specs and DO-35 package; differs only in qualification level (JANTX vs. JAN); JANTX requires additional screening per MIL-PRF-19500/435. | Required for programs specifying JANTX-level testing (e.g., certain DoD procurement contracts); same footprint and function. | Choose if contract documentation mandates JANTX screening; otherwise JAN suffices for most high-reliability applications. |
Compared with 1N4100US-1 and JANTX1N4100C-1, JAN1N4100C-1/TR offers optimal balance of axial-lead serviceability, 250 °C/W junction-to-lead thermal resistance, and JAN-level qualification - making it preferred for repairable, conduction-cooled, and field-maintainable military electronics.

FAQ
What is the Zener voltage tolerance of JAN1N4100C-1/TR?
JAN1N4100C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its nomenclature. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, where 1N4100-1 (base part) is listed with nominal 7.5 V and "C" indicating 2% tolerance. The device is tested at 250 mA (IZT) under thermal equilibrium at 25 °C.
Is JAN1N4100C-1/TR RoHS compliant?
No, JAN1N4100C-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts; JAN-level devices like JAN1N4100C-1/TR use traditional tin-lead plating and are exempt from RoHS per MIL-PRF-19500/435 requirements for high-reliability applications.
What does the "TR" suffix mean in JAN1N4100C-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. As stated on page 2 of the datasheet, "Tape & Reel option: Standard per EIA-296 (add 'TR' suffix to part number). Consult factory for quantities." JAN1N4100C-1/TR retains identical electrical and mechanical specifications as JAN1N4100C-1.
What is the maximum Zener current IZM for JAN1N4100C-1/TR?
The maximum Zener current IZM for JAN1N4100C-1/TR is 40 mA, as specified in the Electrical Characteristics table (page 3) under "MAXIMUM ZENER CURRENT IZM" for 1N4100-1. This value is derived from the 500 mW power rating and 7.5 V Zener voltage (P = V × I → I = 0.5 W / 7.5 V ≈ 66.7 mA), but the datasheet explicitly limits IZM to 40 mA to ensure safe operation within thermal and reliability margins.
How is polarity marked on JAN1N4100C-1/TR?
Polarity is marked by a cathode band on the glass body of JAN1N4100C-1/TR. As stated on page 2: "POLARITY: Cathode indicated by band. The diode is to be operated with the banded end positive with respect to the opposite end for Zener regulation." This means the banded end is the cathode and must be connected to the higher-potential node in shunt regulation configurations.
