Product details
Overview
JAN1N4104-1/TR from Microsemi is a 10.0 V, 500 mW axial-leaded glass Zener diode in DO-35 (DO-204AH) package, qualified to JAN level per MIL-PRF-19500/435, with 5% voltage tolerance, 200 Ω dynamic impedance at 250 mA test current, and 0.5 µA maximum reverse leakage at 7.6 V. It serves as a precision voltage reference in military-grade power supply regulation and analog signal conditioning circuits.
For engineers reviewing the JAN1N4104-1/TR datasheet, JAN1N4104-1/TR pinout, JAN1N4104-1/TR application, or JAN1N4104-1/TR equivalent, key selection criteria include Zener voltage stability over temperature (αVZ = +0.080 %/°C), low noise density (1 µV/√Hz typical), hermetic glass packaging for high-reliability environments, and compatibility with manual or wave soldering per MIL-STD-750.
Technical Context
This device operates in reverse breakdown mode with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. Its metallurgically bonded junction ensures stable Zener characteristics under thermal cycling and radiation exposure.
The 10.0 V nominal Zener voltage is specified at IZT = 250 mA, with ZZT = 200 Ω measured using 10% rms ac modulation superimposed on IZT. Power dissipation derates linearly from 500 mW at TC = 25 °C to zero at 175 °C, with RθJL = 250 °C/W when mounted with 3/8″ lead length.
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 |
|---|---|---|---|
| 1N4104US | Same 10.0 V Zener voltage and JAN qualification, but in surface-mount DO-213AA package | Requires SMT reflow process; unsuitable for through-hole prototyping or repair | Select when board space is constrained and automated assembly is used |
| JANTXV1N4104-1 | Identical electrical specs but qualified to JANTXV level with enhanced screening and tighter parametric limits | Required for mission-critical subsystems where burn-in and lot acceptance testing are mandated | Select when higher reliability assurance beyond JAN level is contractually required |
Compared with JAN1N4104-1/TR, 1N4104US offers footprint reduction at the cost of assembly flexibility, while JANTXV1N4104-1 delivers extended screening rigor for systems where failure modes carry catastrophic consequences-neither is pin-compatible due to differing packages or qualification scope.

FAQ
What is the Zener voltage tolerance for JAN1N4104-1/TR?
JAN1N4104-1/TR has a nominal Zener voltage of 10.0 V with ±5% tolerance, consistent with the standard JEDEC specification for the 1N4099–1N4135 series. This tolerance is verified per MIL-PRF-19500/435 screening requirements at 25 °C ambient and applies across the full qualified temperature range when operated within rated power limits.
Does JAN1N4104-1/TR require heatsinking in typical applications?
No, JAN1N4104-1/TR does not require external heatsinking in standard applications. With a thermal resistance of 250 °C/W junction-to-lead (at 3/8″ lead length) and 300 °C/W junction-to-ambient, it safely dissipates its full 500 mW rating at case temperatures up to 50 °C. Derating begins linearly above that point, reaching zero power at 175 °C junction temperature.
Is JAN1N4104-1/TR RoHS compliant?
No, JAN1N4104-1/TR is not RoHS compliant. The "TR" suffix denotes tape-and-reel packaging, while RoHS compliance is only available on commercial-grade versions marked with the "e3" suffix (e.g., 1N4104-1e3/TR). JAN-level devices use traditional tin-lead plating per MIL-STD-750 for proven solderability and reliability in high-reliability assemblies.
What is the maximum reverse leakage current for JAN1N4104-1/TR?
The maximum reverse leakage current for JAN1N4104-1/TR is 0.5 µA at VR = 7.6 V, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This value is measured at 25 °C and represents worst-case leakage under sub-breakdown bias conditions relevant to standby power budgeting.
Can JAN1N4104-1/TR be used in surface-mount designs?
No, JAN1N4104-1/TR is packaged in the axial-leaded DO-35 (DO-204AH) glass case and is intended for through-hole mounting. For surface-mount equivalents, consider the 1N4104US in DO-213AA or 1PMT4104 in DO-216 - both share identical electrical specifications but differ in mechanical form factor and qualification level.
