Product details
Overview
JAN1N4135-1/TR from Microsemi is a 100 V, 500 mW axial-leaded glass Zener diode in DO-35 (DO-204AH) package, qualified to JANS level per MIL-PRF-19500/435, with ±5% voltage tolerance, 1600 Ω dynamic impedance at 250 mA test current, and 3.8 mA maximum Zener current for precision voltage regulation in high-reliability military and aerospace power supply circuits.
For engineers reviewing the JAN1N4135-1/TR datasheet, JAN1N4135-1/TR pinout, JAN1N4135-1/TR application, or JAN1N4135-1/TR equivalent, key selection criteria include its 100 V nominal Zener voltage, JANS-level qualification, 500 mW power rating with thermal derating above 50 °C, low reverse leakage (≤0.01 µA at 76 V), and metallurgically bonded glass construction for radiation hardness and long-term stability.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, delivering stable 100 V regulation across 250 mA test current and up to 76 mA maximum Zener current. Its metallurgical bond ensures low noise density (≤1 µV/√Hz below 6.8 V, rising to 40 µV/√Hz at higher voltages) and minimal capacitance (typical <1 pF).
Designed for high-reliability environments, it supports operation from –65 °C to +175 °C junction temperature, exhibits +0.100 %/°C temperature coefficient, and maintains hermetic seal integrity per MIL-PRF-19500/435 requirements for JAN, JANTX, JANTXV, and JANS reliability levels.
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 |
|---|---|---|---|
| 1N4135US | Same 100 V Zener voltage, DO-213AA surface-mount package, no axial leads, 300 mW rating | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy board repair | Select when automated assembly and space-constrained layouts outweigh need for manual replacement or socket compatibility |
| JANS1N4135-1 | Identical electrical specs and DO-35 package, but certified to full JANS screening (including 100% lot acceptance testing and extended temperature cycling) | Required for DoD-specified Class K or Class H programs where JANS certification is contractually mandated | Choose only when procurement documentation explicitly requires JANS-level certification beyond JAN-level qualification |
Compared with 1N4135US and JANS1N4135-1, JAN1N4135-1/TR offers the optimal balance of JANS-compatible reliability, axial-leaded serviceability, and tape-and-reel logistics for medium-volume production of defense-grade power supplies.

FAQ
What is the Zener voltage tolerance for JAN1N4135-1/TR?
JAN1N4135-1/TR has a nominal Zener voltage of 100 V with ±5% tolerance, consistent with the JEDEC-standard 1N4099–1N4135-1 family. This tolerance is measured at 25 °C with the diode in thermal equilibrium and applies to all JAN-level variants unless otherwise specified in the ordering nomenclature.
Is JAN1N4135-1/TR RoHS compliant?
No, JAN1N4135-1/TR is not RoHS compliant. Per the Microsemi datasheet T4-LDS-0245-2, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts; JAN-level devices like JAN1N4135-1/TR retain tin-lead plating to meet MIL-STD-750 solderability requirements and reliability validation protocols.
What is the maximum allowable junction temperature for JAN1N4135-1/TR?
The maximum junction and storage temperature for JAN1N4135-1/TR is +175 °C, with a minimum of –65 °C. Thermal resistance junction-to-ambient is 300 °C/W on FR4 board with 4 mm² copper pads, and junction-to-lead is 250 °C/W with 10 mm lead length, enabling operation in extreme environmental conditions typical of aerospace and defense platforms.
How does the temperature coefficient affect JAN1N4135-1/TR's regulation accuracy?
JAN1N4135-1/TR has a temperature coefficient of +0.100 %/°C, meaning its Zener voltage increases by 0.1% per degree Celsius rise in junction temperature. Over a –55 °C to +125 °C range, this results in approximately ±18 V total drift, which must be compensated in precision applications using external temperature compensation networks or calibration routines.
Can JAN1N4135-1/TR be used in surface-mount designs?
No, JAN1N4135-1/TR uses the axial-leaded DO-35 (DO-204AH) package and is not suitable for surface-mount assembly. For SMT equivalents, consider the 1N4135UR-1 in DO-213AA or 1PMT4135 in DO-216 packages - both share identical 100 V Zener voltage but differ in power rating, package geometry, and qualification level.
