Product details
Overview
JAN1N4105-1 from Microsemi is a 500 mW, 11.0 V 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 0.05 µA maximum reverse leakage at 8.5 V. It serves as a precision voltage reference in military-grade power supply regulation.
For engineers reviewing the JAN1N4105-1 datasheet, JAN1N4105-1 pinout, JAN1N4105-1 application, or JAN1N4105-1 equivalent, key selection criteria include its MIL-qualified reliability, low noise density (1 µV/√Hz), thermal stability (±0.080 %/°C tempco), and hermetically sealed DO-35 construction for high-reliability analog and aerospace systems.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 11.0 V regulation across wide current (250 mA IZT) and temperature (–65 °C to +175 °C) ranges. Its metallurgically bonded junction ensures low noise and radiation hardness per MicroNote 050.
The device exhibits 200 Ω dynamic impedance at 250 mA, 0.05 µA reverse leakage at VR = 8.5 V, and a positive temperature coefficient of +0.080 %/°C - enabling predictable drift compensation in precision reference circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4105US | Same 11.0 V Zener voltage, but in surface-mount DO-213AA package; no MIL qualification | Used in commercial industrial controllers where board space is constrained and MIL screening not required | Select when footprint reduction and RoHS compliance are prioritized over radiation hardness and extended temperature validation |
| JANTX1N4105 | Identical electrical specs and DO-35 package; qualified to JANTX level (higher screening than JAN) | Deployed in flight-critical subsystems requiring enhanced burn-in and lot acceptance testing per MIL-PRF-19500/435 | Select when system-level reliability mandates tighter parametric limits and extended life testing beyond JAN baseline |
Compared with JAN1N4105-1, 1N4105US trades MIL qualification and radiation tolerance for compact SMT integration, while JANTX1N4105 retains identical form-factor and performance but adds higher-tier screening - making it suitable for mission-critical avionics where failure modes demand stricter process control.

FAQ
What is the Zener voltage tolerance for JAN1N4105-1?
JAN1N4105-1 has a nominal Zener voltage of 11.0 V with a standard tolerance of ±5%, as defined in the JEDEC-registered specification and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies under thermal equilibrium at 25 °C with 250 mA test current.
Is JAN1N4105-1 RoHS compliant?
No - JAN1N4105-1 is not RoHS compliant. Per the nomenclature guide on page 2 of T4-LDS-0245-2 Rev. 1, the "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions (e.g., 1N4105-1e3). The JAN prefix indicates military-grade qualification with tin-lead plating, exempt from RoHS directives.
What is the maximum reverse leakage current for JAN1N4105-1?
JAN1N4105-1 has a maximum reverse leakage current (IR) of 0.05 µA at VR = 8.5 V, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This value is measured at 25 °C and reflects tight leakage control critical for high-impedance reference applications.
Does JAN1N4105-1 require derating above 25 °C?
Yes - JAN1N4105-1 must be linearly derated starting at 25 °C ambient temperature, with rated power dissipation decreasing from 500 mW to zero at 175 °C, per Figure 2 and Note 2 on page 2 of T4-LDS-0245-2 Rev. 1. Derating follows a slope of approximately 3.57 mW/°C.
What does the "-1" suffix mean in JAN1N4105-1?
The "-1" suffix in JAN1N4105-1 denotes Microsemi's internal revision level and packaging configuration, indicating compliance with the DO-35 (DO-204AH) mechanical outline and metallurgical bonding process defined in T4-LDS-0245-2 Rev. 1. It is not a JEDEC-standard suffix but a manufacturer-specific identifier tied to the qualified build.
