Product details
Overview
JAN1N4135C-1 from Microsemi is a 100 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4135C-1 datasheet, JAN1N4135C-1 pinout, JAN1N4135C-1 application, or JAN1N4135C-1 equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - critical for precision reference and ruggedized analog design.
Technical Context
This device operates as a reverse-biased voltage reference with nominal Zener voltage of 100 V at 250 mA test current, ±2% tolerance (denoted by "C" suffix), and +0.100 %/°C temperature coefficient. Its metallurgical bond construction ensures stable regulation across -65 °C to +175 °C junction temperature range.
It exhibits 1600 Ω maximum dynamic impedance (ZZT) at IZT = 250 mA, 40 µV/√Hz max noise density above 6.8 V (typical for 100 V part), and 0.01 µA maximum reverse leakage (IR) at VR = 80 V - enabling low-drift, low-noise reference performance in regulated DC supplies.

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, but in surface-mount DO-213AA package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy board repair | Select when automated assembly and space-constrained layouts are prioritized over manual serviceability |
| JANTXV1N4135C-1 | Identical electrical specs, but qualified to JANTXV level (enhanced screening, tighter parametric limits) | Required for flight-critical subsystems where extended burn-in and lot acceptance testing are mandated | Select when program-level reliability requirements exceed JAN-level screening criteria |
Compared with JAN1N4135C-1, 1N4135US-1 trades axial-mount flexibility for SMT compatibility, while JANTXV1N4135C-1 adds cost and lead time for higher-screened units - enabling selection based on assembly method and reliability tier without sacrificing Zener accuracy or thermal performance.

FAQ
What is the Zener voltage tolerance of JAN1N4135C-1?
JAN1N4135C-1 has a nominal Zener voltage of 100 V with ±2% tolerance, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified temperature range when used within derated power limits. The JAN1N4135C-1 meets MIL-PRF-19500/435 requirements for this parameter.
Is JAN1N4135C-1 RoHS compliant?
No, JAN1N4135C-1 is not RoHS compliant. Per the datasheet, RoHS-compliant versions (suffix "e3") are available only for commercial-grade variants, not for JAN-level qualified parts like JAN1N4135C-1. The JAN1N4135C-1 uses traditional tin-lead plating per MIL-STD-750, method 2026, and retains lead content required for military solderability standards.
What is the maximum reverse leakage current for JAN1N4135C-1?
The maximum reverse leakage current (IR) for JAN1N4135C-1 is 0.01 µA at VR = 80 V, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This value is measured at 25 °C and reflects the device's tight leakage control - a key factor in high-impedance reference applications where leakage-induced error must be minimized. The JAN1N4135C-1 maintains this spec across its qualified temperature range when operated within rated power limits.
Does JAN1N4135C-1 have radiation hardness certification?
Yes, JAN1N4135C-1 is inherently radiation hard, as documented in Microsemi MicroNote 050. While not individually tested per MIL-STD-883, its metallurgically bonded DO-35 construction and material system provide proven tolerance to total ionizing dose (TID) environments - making it suitable for use in satellite and nuclear instrumentation without additional radiation mitigation. This property is intrinsic to the JAN1N4135C-1 design and confirmed in Microsemi's technical documentation.
What is the thermal resistance junction-to-lead for JAN1N4135C-1?
The thermal resistance junction-to-lead (RθJL) for JAN1N4135C-1 is 250 °C/W when mounted with 3/8 inch (10 mm) lead length from the body, per the Maximum Ratings table on page 1 of the datasheet. This value enables accurate thermal modeling of power dissipation in chassis-mounted or heatsink-attached configurations. For PCB-mounted use, RθJA = 300 °C/W applies, and the JAN1N4135C-1 must be derated linearly from 500 mW starting at 50 °C lead temperature.
