Product details
Overview
JANTX1N4127D-1 from Microsemi is a 56 V, 1% tolerance, 500 mW axial-leaded glass Zener diode in DO-35 (DO-204AH) package, metallurgically bonded for high-reliability voltage regulation in military and aerospace power conditioning circuits.
For engineers reviewing the JANTX1N4127D-1 datasheet, JANTX1N4127D-1 pinout, JANTX1N4127D-1 application, or JANTX1N4127D-1 equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and MIL-PRF-19500/435 qualification details required for precision reference and overvoltage protection design.
Technical Context
JANTX1N4127D-1 operates as a reverse-biased Zener regulator with nominal VZ = 56 V at IZT = 250 mA, exhibiting αVZ = +0.100 %/°C and ZZT = 300 Ω. Its metallurgical bond ensures stable breakdown characteristics under thermal cycling and radiation exposure.
The device delivers low noise density (ND = 1 µV/√Hz), minimal capacitance (typ. <1.5 pF), and is rated for TJ = –65 to +175 °C. It is qualified to JANTX level per MIL-PRF-19500/435, supporting operation in high-reliability analog reference and voltage-clamp functions without derating below 50 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N4127D-1 | Same electrical specs; qualified to JANS (highest reliability level) with extended screening and 100% lot testing. | Required for Class S spaceflight hardware; supports higher confidence in mission-critical fault-tolerant systems. | Select when full JANS qualification, radiation assurance beyond TID, or extended temperature screening is mandated. |
| 1N4127DUR-1 | Same VZ, tolerance, and noise performance; surface-mount DO-213AA package instead of axial DO-35. | Used where PCB space is constrained and automated assembly is required; lacks axial mounting flexibility. | Select for high-density SMT layouts or reflow-compatible production; verify thermal pad layout matches RθJL = 250 °C/W requirement. |
Compared with JANTX1N4127D-1, JANS1N4127D-1 adds full space-level screening and radiation validation, while 1N4127DUR-1 trades axial mounting for SMT compatibility-neither is pin-compatible due to differing packages, but both maintain identical Zener regulation behavior at 56 V.
