Product details
Overview
JANS1N4135-1/TR from Microsemi is a 100 V, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers ±5% Zener voltage tolerance at 250 mA test current, exhibits 1600 Ω dynamic impedance, and maintains stable regulation across -65 °C to +175 °C junction temperature range.
For engineers reviewing the JANS1N4135-1/TR datasheet, JANS1N4135-1/TR pinout, JANS1N4135-1/TR application, or JANS1N4135-1/TR equivalent, key selection criteria include its 100 V nominal Zener voltage, JANS-level radiation-hardened qualification, 40 µV/√Hz noise density at ≥6.8 V, hermetic DO-35 packaging, and compliance with MIL-STD-750 ESD testing.
Technical Context
This device operates as a precision voltage reference and shunt regulator in high-stability analog circuits, leveraging metallurgical bonding to minimize parameter drift under thermal and radiation stress. Its Zener breakdown mechanism is optimized for low-noise operation above 6.8 V, with noise density dropping to 1 µV/√Hz at lower voltages.
The JANS1N4135-1/TR is characterized at 250 mA Zener test current (IZT), with dynamic impedance measured using 10% rms ac modulation superimposed on IZT. Temperature coefficient is +0.100 %/°C, enabling predictable voltage shift over wide operating ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4135US-1 | Same 100 V Zener voltage and JANS qualification, but in surface-mount DO-213AA package | Requires PCB re-layout for SMT assembly; no axial lead mounting option | Select when automated assembly and board space reduction outweigh axial-lead serviceability needs |
| JANTXV1N4135-1 | Identical electrical specs and DO-35 package, but qualified only to JANTXV level (not JANS) | Lacks full radiation hardness validation required for spaceflight missions | Select for high-reliability ground-based military systems where full JANS testing is not mandated |
Compared with JANTXV1N4135-1 and 1N4135US-1, the JANS1N4135-1/TR provides the highest assurance of radiation tolerance and hermetic integrity, making it the sole choice for Class S space applications-while retaining identical Zener voltage, impedance, and thermal performance in the DO-35 form factor.

FAQ
What is the Zener voltage tolerance for JANS1N4135-1/TR?
The JANS1N4135-1/TR has a nominal Zener voltage of 100 V with a standard tolerance of ±5%, as defined by JEDEC registration and verified per MIL-PRF-19500/435 test requirements. This tolerance applies at 250 mA test current and 25 °C ambient temperature, and is maintained across the full JANS qualification lot acceptance testing.
Is JANS1N4135-1/TR compatible with lead-free soldering processes?
Yes, JANS1N4135-1/TR supports lead-free soldering with a maximum solder temperature of 260 °C for 10 seconds, per MIL-STD-750 Method 2026. The leads are plated with RoHS-compliant annealed matte-tin (on commercial versions); JANS-grade units use tin-lead plating but remain compatible with Pb-free reflow profiles due to thermal design margins.
What is the maximum junction temperature rating for JANS1N4135-1/TR?
The JANS1N4135-1/TR is rated for junction and storage temperatures from -65 °C to +175 °C, as confirmed in the T4-LDS-0245-2 datasheet. This rating is validated through JANS-level environmental stress screening, including thermal cycling and high-temperature life testing per MIL-PRF-19500/435.
Does JANS1N4135-1/TR require derating above 25 °C ambient?
Yes, JANS1N4135-1/TR must be linearly derated from 500 mW starting at 25 °C ambient temperature, reaching zero power dissipation at 175 °C. Derating follows a slope of -3.33 mW/°C, based on thermal resistance junction-to-ambient (300 °C/W) on a typical FR4 board with specified copper pad geometry.
How is polarity marked on JANS1N4135-1/TR?
JANS1N4135-1/TR uses a cathode band to indicate polarity: the banded end is the cathode and must be held at a higher potential than the anode for Zener regulation. This marking complies with JEDEC standards and is laser-etched or ink-marked on the DO-35 glass body per Microsemi's mechanical specification.
