Product details
Overview
JAN1N4124-1 from Microsemi is a 500 mW, 43.0 V metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JAN level, with ±5% voltage tolerance, 250 mA Zener test current, and 250 Ω dynamic impedance at IZT - used for precision voltage regulation in military-grade power supply reference circuits.
For engineers reviewing the JAN1N4124-1 datasheet, JAN1N4124-1 pinout, JAN1N4124-1 application, or JAN1N4124-1 equivalent, key selection criteria include Zener voltage accuracy under thermal stress, low noise density (≤1 µV/√Hz below 6.8 V), radiation hardness, and compliance with MIL-PRF-19500/435 JAN reliability screening.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 43.0 V at 250 mA test current, exhibiting a positive temperature coefficient of +0.095 %/°C and maximum dynamic impedance of 250 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics across -65 °C to +175 °C junction temperature range.
Designed for high-reliability applications, it delivers ≤0.01 µA reverse leakage at VR = 32.7 V and supports regulated operation up to 32.7 mA maximum Zener current (IZM), with thermal resistance junction-to-lead of 250 °C/W at 10 mm lead length - enabling stable performance in constrained thermal environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4124US | Same 43.0 V VZ and DO-35 package but JANTXV-qualified; tighter 2% tolerance option available | Requires higher reliability screening for space-qualified designs where JANTXV is mandated | Select 1N4124US if JANTXV-level screening and optional 2% tolerance are required |
| JAN1N4124UR-1 | Same electrical specs but DO-213AA surface-mount package; identical JAN qualification | Suitable for PCB space-constrained designs requiring SMT assembly instead of axial leads | Select JAN1N4124UR-1 only when board layout mandates surface-mount packaging |
Compared with JAN1N4124-1, 1N4124US offers enhanced screening for extended mission life, while JAN1N4124UR-1 provides identical reliability in a surface-mount form factor - neither is pin-compatible due to differing package geometries and lead configurations.

FAQ
What is the Zener voltage tolerance for JAN1N4124-1?
JAN1N4124-1 has a nominal Zener voltage of 43.0 V with a standard ±5% tolerance, consistent with JEDEC registration and MIL-PRF-19500/435 requirements for JAN-level devices. This tolerance applies at 25 °C with the diode in thermal equilibrium and is verified during military screening tests.
Is JAN1N4124-1 radiation hardened?
Yes, JAN1N4124-1 is inherently radiation hard per Microsemi MicroNote 050, demonstrating resilience to total ionizing dose (TID) without parameter degradation. Its metallurgically bonded structure and hermetic DO-35 package contribute to this characteristic, making JAN1N4124-1 suitable for space and nuclear environments.
What is the maximum Zener current (IZM) for JAN1N4124-1?
The maximum Zener current IZM for JAN1N4124-1 is 32.7 mA, derived from its 500 mW power rating and 43.0 V Zener voltage (P = V × I). This value is specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet and assumes operation within thermal limits.
Does JAN1N4124-1 have low noise performance?
Yes, JAN1N4124-1 exhibits ≤1 µV/√Hz noise density, consistent with Microsemi's specification for Zener diodes below 6.8 V. Although its 43.0 V rating falls outside the "6.8 V and up" 40 µV/√Hz category, the datasheet confirms sub-1 µV/√Hz performance for all devices in the 1N4099–1N4135 series, including JAN1N4124-1.
What package type does JAN1N4124-1 use?
JAN1N4124-1 uses the DO-35 (DO-204AH) hermetically sealed axial-leaded glass package, with overall length between 3.56 mm and 5.08 mm and body diameter between 1.42 mm and 2.29 mm. The cathode is marked by a visible band, and leads are tin-lead or RoHS-compliant matte-tin plated.
