Product details
Overview
JANS1N4105C-1/TR from Microsemi is a 500 mW, 11.0 V ±2% metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers stable voltage regulation at 250 mA test current, with dynamic impedance of 200 Ω, max reverse leakage of 0.05 µA at 8.5 V, and temperature coefficient of +0.080 %/°C.
For engineers reviewing the JANS1N4105C-1/TR datasheet, JANS1N4105C-1/TR pinout, JANS1N4105C-1/TR application, or JANS1N4105C-1/TR equivalent, key selection criteria include military-grade reliability qualification, low-noise performance (≤1 µV/√Hz below 6.8 V), tight 2% Zener tolerance, hermetic DO-35 packaging, and radiation-hardened construction per MicroNote 050.
Technical Context
This JANS-level Zener diode operates in reverse breakdown to maintain precise DC reference voltage across wide current (250 mA IZT) and temperature (–65 °C to +175 °C) ranges. Its metallurgical bond ensures mechanical robustness under thermal cycling and shock, while the hermetically sealed DO-35 glass package prevents moisture ingress and supports long-term parametric stability in harsh environments.
Designed for high-reliability analog reference and biasing functions, it exhibits low noise density (≤1 µV/√Hz), minimal capacitance (typ. <2 pF), and predictable temperature coefficient (+0.080 %/°C). Its 250 °C/W junction-to-lead thermal resistance enables reliable power dissipation up to 500 mW at controlled lead temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4105C-1 | Same electrical specs and DO-35 package, but qualified only to JANTXV level (not JANS); lacks full Class S radiation testing. | Approved for high-reliability ground-based military systems, not spaceflight or nuclear-hardened platforms. | Select when full JANS qualification is not required and cost sensitivity favors lower-tier military grade. |
| 1N4105C-1/TR | Commercial-grade version with RoHS-compliant matte-tin plating; no MIL-PRF-19500 qualification or radiation hardening. | Intended for industrial test equipment and non-safety-critical embedded systems with standard environmental requirements. | Choose for cost-sensitive prototyping or commercial production where military reliability and radiation tolerance are unnecessary. |
Compared with JANS1N4105C-1/TR, JANTXV1N4105C-1 offers identical performance with reduced radiation assurance, while 1N4105C-1/TR eliminates qualification overhead entirely-making the JANS variant essential only where space, nuclear, or Class S mission assurance is mandated.

FAQ
What is the Zener voltage tolerance of JANS1N4105C-1/TR?
JANS1N4105C-1/TR has a nominal Zener voltage of 11.0 V with a tolerance of ±2%, denoted by the "C" suffix in the part number per Microsemi's nomenclature. This tight tolerance is maintained across the full operating temperature range of –65 °C to +175 °C and is verified during JANS-level qualification testing.
Is JANS1N4105C-1/TR radiation hardened?
Yes, JANS1N4105C-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 package provide proven resilience to total ionizing dose (TID) and displacement damage, supporting use in space and nuclear environments without additional shielding.
What does the "TR" suffix mean in JANS1N4105C-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated placement in high-volume manufacturing. JANS1N4105C-1/TR is supplied in reels compatible with standard pick-and-place equipment, with quantities configurable per customer requirement.
How does JANS1N4105C-1/TR differ from commercial 1N4105C-1/TR?
JANS1N4105C-1/TR is fully qualified to MIL-PRF-19500/435 JANS level-including lot traceability, extended environmental testing, and radiation hardness validation-whereas 1N4105C-1/TR is commercial-grade with RoHS compliance but no military qualification or radiation assurance.
What is the maximum reverse leakage current for JANS1N4105C-1/TR?
JANS1N4105C-1/TR specifies a maximum reverse leakage current (IR) of 0.05 µA at VR = 8.5 V, measured at 25 °C. This ultra-low leakage ensures minimal error contribution in high-impedance reference and bias networks, especially critical in battery-powered or low-power instrumentation.
