Product details
Overview
JAN1N4130C-1/TR from Microsemi is a 68 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 JAN1N4130C-1/TR datasheet, JAN1N4130C-1/TR pinout, JAN1N4130C-1/TR application, or JAN1N4130C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), JANS-qualified thermal stability (−65 °C to +175 °C), and hermetic DO-35 packaging for harsh-environment operation.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 68 V at 250 mA test current, exhibiting a temperature coefficient of +0.100 %/°C and dynamic impedance of 700 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for regulated DC supply rails in analog instrumentation and avionics, it delivers ≤0.01 µA reverse leakage at 54.4 V and supports linear derating from 500 mW at 25 °C to zero at 175 °C, with junction-to-lead thermal resistance of 250 °C/W when mounted with 3/8″ lead length.

FAQ
What is the Zener voltage tolerance of JAN1N4130C-1/TR?
JAN1N4130C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its nomenclature. This means its actual breakdown voltage falls within 66.64 V to 69.36 V at 250 mA test current and 25 °C, meeting stringent requirements for precision regulation in defense electronics where tighter tolerances reduce calibration overhead.
Is JAN1N4130C-1/TR RoHS compliant?
No, JAN1N4130C-1/TR is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4130C-1e3); JAN-level parts retain traditional tin-lead plating per MIL-STD-750 to ensure solderability and reliability in high-reliability military applications where lead-free alternatives have not been fully qualified.
What does the "TR" suffix indicate in JAN1N4130C-1/TR?
The "TR" suffix in JAN1N4130C-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format is standard for volume orders and supports consistent feeding in high-throughput SMT lines, though the device itself remains a through-hole DO-35 component requiring manual or wave-solder insertion after placement.
What is the maximum reverse leakage current for JAN1N4130C-1/TR?
JAN1N4130C-1/TR specifies a maximum reverse leakage current (IR) of 0.01 µA at 54.4 V (80% of nominal VZ). This ultra-low leakage ensures minimal power loss in high-impedance bias networks and preserves accuracy in precision reference circuits where even nanoamp-level errors degrade system resolution.
How is thermal derating applied to JAN1N4130C-1/TR?
JAN1N4130C-1/TR linearly derates from 500 mW at 25 °C to zero at 175 °C ambient, with a defined junction-to-ambient thermal resistance of 300 °C/W on FR4 board. For lead-temperature-limited operation, derating begins at 50 °C using RθJL = 250 °C/W, allowing full power up to 50 °C case temperature before reduction.
