Product details
Overview
JAN1N4124D-1 from Microsemi is a 500 mW, 43.0 V Zener voltage regulator diode in DO-35 (DO-204AH) glass axial-leaded package, qualified to JAN reliability level per MIL-PRF-19500/435, with 1% Zener voltage tolerance, 250 mA test current, and 250 Ω maximum dynamic impedance at 25 °C.
For engineers reviewing the JAN1N4124D-1 datasheet, JAN1N4124D-1 pinout, JAN1N4124D-1 application, or JAN1N4124D-1 equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (≤1 μV/√Hz below 6.8 V), radiation hardness, hermetic glass sealing, and military-grade thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage reference in reverse-biased breakdown mode, with Zener voltage specified at IZT = 250 mA and dynamic impedance measured at 10% ac modulation of IZT. Its metallurgically bonded construction ensures stable regulation across wide current (0.01–32.7 mA max) and temperature (−65 to +175 °C) ranges.
It exhibits a positive temperature coefficient of +0.095 %/°C, minimal capacitance (typical <2 pF at 43 V), and low leakage (IR ≤ 0.01 µA at VR = 34.4 V), making it suitable for high-stability analog references and radiation-tolerant power supply feedback paths.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4124US-1 | Same electrical specs, but in surface-mount DO-213AA package | Requires SMT assembly; no axial through-hole mounting | Select when board space is constrained and reflow capability exists |
| JANTXV1N4124D | Identical Zener parameters, but qualified to JANTXV level with extended screening | Higher cost and longer lead time; required only for Class H/V systems | Select when full JANTXV screening per MIL-PRF-19500/435 is mandated |
Compared with JAN1N4124D-1, 1N4124US-1 offers identical regulation performance in a compact SMT form factor, while JANTXV1N4124D provides enhanced reliability screening for higher assurance programs-neither is pin-compatible due to differing packages or qualification scope.
