Product details
Overview
JANTXV1N4625D-1 from Microsemi is a 500 mW, 5.1 V Zener voltage regulator diode in DO-35 (DO-204AH) axial-glass package, qualified to JANTXV level per MIL-PRF-19500/435, with 1% voltage tolerance, 1500 Ω dynamic impedance at 250 mA test current, and ±0.045%/°C to +0.030%/°C temperature coefficient. It serves as a precision reference in military-grade power supply regulation and analog signal conditioning.
For engineers reviewing the JANTXV1N4625D-1 datasheet, JANTXV1N4625D-1 pinout, JANTXV1N4625D-1 application, or JANTXV1N4625D-1 equivalent, key selection factors include its 1% Zener voltage tolerance, metallurgically bonded construction for reliability, low noise density (2 µV/√Hz), and operation across –65 °C to +175 °C junction temperature range.
Technical Context
This device operates in reverse-bias breakdown mode to maintain stable 5.1 V output across wide current (250 mA IZT) and temperature (–65 °C to +175 °C) ranges. Its metallurgical bond ensures mechanical robustness under thermal cycling and shock, critical for aerospace and defense systems.
The Zener exhibits a non-linear temperature coefficient of –0.045%/°C to +0.030%/°C, enabling predictable drift compensation in reference circuits. Dynamic impedance of 1500 Ω at 250 mA defines regulation stiffness, while 500 mW power rating supports moderate load current sourcing with linear derating above 50 °C lead temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4625US-1 | Same 5.1 V, 1% tolerance, but in surface-mount DO-213AA package | Requires PCB rework for SMT assembly; lacks axial-lead mounting flexibility | Select when board space is constrained and automated placement is required |
| JANTXV1N4625-1 | Same electrical specs but 5% Zener tolerance instead of 1% | Higher initial voltage uncertainty requires calibration or trimming in precision circuits | Select when cost sensitivity outweighs need for tight tolerance |
Compared with JANTXV1N4625D-1, the JANTXV1N4625-1 offers lower cost but sacrifices 4% absolute voltage accuracy, while the 1N4625US-1 retains identical regulation performance but shifts to surface-mount form factor-neither is pin-compatible due to differing packages and lead configurations.

FAQ
What is the Zener voltage tolerance of JANTXV1N4625D-1?
JANTXV1N4625D-1 has a nominal Zener voltage of 5.1 V with ±1% tolerance, verified per MIL-PRF-19500/435 test requirements. This tight tolerance eliminates the need for post-manufacture calibration in high-accuracy reference designs and is explicitly defined in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet.
Is JANTXV1N4625D-1 qualified for space applications?
JANTXV1N4625D-1 is qualified to JANTXV level per MIL-PRF-19500/435 and exhibits inherent radiation hardness as documented in Microsemi MicroNote 050. While not JANS-qualified out-of-box, it is widely used in LEO spacecraft telemetry systems where its DO-35 hermetic construction and metallurgical bond provide proven reliability under total ionizing dose exposure.
What is the maximum operating temperature for JANTXV1N4625D-1?
JANTXV1N4625D-1 supports a junction and storage temperature range of –65 °C to +175 °C, as specified in the Maximum Ratings table on page 1 of the T4-LDS-0245-2 datasheet. Derating begins at 50 °C lead temperature, with zero power allowed at 175 °C, making it suitable for engine bay, avionics bay, and space ambient environments.
Does JANTXV1N4625D-1 have low-noise performance?
Yes, JANTXV1N4625D-1 delivers 2 µV/√Hz noise density at 250 mA Zener test current, measured in the 1 kHz–3 kHz band per Figure 1. This low noise is confirmed in the Electrical Characteristics table and makes JANTXV1N4625D-1 appropriate for precision analog references where noise-induced error must remain below 1 LSB in 16-bit ADC systems.
What package type does JANTXV1N4625D-1 use?
JANTXV1N4625D-1 uses the DO-35 (DO-204AH) axial-leaded, hermetically sealed glass package with cathode band marking. Dimensions are fully specified on page 5 of T4-LDS-0245-2, including body diameter (0.056–0.090 in), body length (0.140–0.200 in), and lead diameter (0.018–0.022 in), ensuring mechanical compatibility with legacy military board layouts.
