Product details
Overview
JANS1N4104C-1/TR from Microsemi is a 10.0 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense voltage regulation applications.
For engineers reviewing the JANS1N4104C-1/TR datasheet, JANS1N4104C-1/TR pinout, JANS1N4104C-1/TR application, or JANS1N4104C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (≤1 μV/√Hz), radiation hardness, and hermetic DO-35 packaging for extreme-environment operation.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 10.0 V at 250 mA test current, exhibiting a temperature coefficient of +0.080 %/°C and dynamic impedance of 200 Ω at IZT. Its metallurgical bond construction ensures stable regulation across wide current and temperature ranges.
Designed for high-reliability mil-spec use, JANS1N4104C-1/TR delivers ≤0.5 µA reverse leakage at 7.6 V, supports 500 mW power dissipation at 25 °C (derated linearly to zero at 175 °C), and maintains <1 pF junction capacitance - critical for low-noise analog reference and timing circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4104C-1 | Same electrical specs and DO-35 package; qualified to JANTXV (not JANS) per MIL-PRF-19500/435. | Lacks full JANS-level screening (e.g., burn-in, lot acceptance testing); not approved for Class S space missions. | Select when JANS-level reliability is not required but JANTXV qualification suffices for high-reliability ground systems. |
| 1N4104C-1/TR | Commercial-grade version; RoHS-compliant plating; no military qualification or radiation hardness data. | Not suitable for aerospace/defense; limited to benign industrial environments with no radiation or extreme thermal cycling. | Select only for cost-sensitive, non-mil applications where full JANS screening adds unnecessary overhead. |
Compared with JANTXV1N4104C-1 and 1N4104C-1/TR, JANS1N4104C-1/TR provides the highest assurance of parametric stability under radiation, thermal shock, and long-term storage - making it the sole choice for Class S spaceflight and nuclear-hardened systems.

FAQ
What is the Zener voltage tolerance for JANS1N4104C-1/TR?
JANS1N4104C-1/TR has a nominal Zener voltage of 10.0 V with a ±2% tolerance, denoted by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is guaranteed over the full operating temperature range and validated during JANS-level qualification testing.
Is JANS1N4104C-1/TR radiation hardened?
Yes, JANS1N4104C-1/TR is inherently radiation hard per Microsemi MicroNote 050, with documented tolerance to total ionizing dose (TID). Its metallurgically bonded structure and hermetic DO-35 package contribute to this hardness, making JANS1N4104C-1/TR suitable for low-earth orbit and nuclear instrumentation applications.
What does the "TR" suffix mean in JANS1N4104C-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated placement in high-volume manufacturing. JANS1N4104C-1/TR is supplied in reels for surface-mount-compatible axial-leaded handling, with full traceability and JANS-level documentation retained.
What is the maximum reverse leakage current for JANS1N4104C-1/TR?
JANS1N4104C-1/TR exhibits a maximum reverse leakage current (IR) of 0.5 µA at 7.6 V (76% of VZ), as specified in the Electrical Characteristics table. This low leakage supports high-impedance bias networks and minimizes power loss in battery-backed systems.
Does JANS1N4104C-1/TR require derating above 25 °C?
Yes, JANS1N4104C-1/TR must be linearly derated from 500 mW starting at 25 °C ambient, reaching zero dissipation at 175 °C. Derating follows the curve in Figure 2 of the datasheet, with thermal resistance junction-to-ambient (RθJA) rated at 300 °C/W on FR4 board with specified copper layout.
