Product details
Overview
JANTXV1N4625C-1/TR from Microsemi is a 500 mW, 5.1 V ±2% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4625C-1/TR datasheet, JANTXV1N4625C-1/TR pinout, JANTXV1N4625C-1/TR application, or JANTXV1N4625C-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - critical for precision biasing, reference, and overvoltage protection in harsh-environment designs.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 5.1 V at 250 mA test current, exhibiting a temperature coefficient of –0.045 %/°C to +0.030 %/°C and dynamic impedance of 1500 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for operation across –65 °C to +175 °C junction temperature range, it delivers low noise density (2 µV/√Hz typical), minimal capacitance (<1 pF at VR = 1 V), and ESD immunity per MIL-STD-750 Method 1020 - enabling use in analog reference chains and sensor excitation circuits where stability and low interference are mandatory.

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/TR | Same electrical specs but in surface-mount DO-213AA package; no axial leads | Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and automated assembly is used |
| JAN1N4625C-1/TR | Identical electrical and mechanical specs but qualified only to JAN level (lower screening than JANTXV) | Lacks extended life testing and radiation hardness validation required for flight-critical subsystems | Select for cost-sensitive ground-support equipment where full JANTXV screening is not mandated |
Compared with JANTXV1N4625C-1/TR, the 1N4625US-1/TR enables miniaturized layouts but sacrifices mechanical robustness, while the JAN1N4625C-1/TR reduces procurement cost and lead time at the expense of radiation tolerance and burn-in validation - making JANTXV the sole choice for mission-critical avionics voltage references.

FAQ
What is the Zener voltage tolerance of JANTXV1N4625C-1/TR?
JANTXV1N4625C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its measured VZ at 250 mA test current falls within 4.998 V to 5.202 V at 25 °C, meeting MIL-PRF-19500/435 requirements for high-precision regulation in critical systems.
Is JANTXV1N4625C-1/TR RoHS compliant?
No, JANTXV1N4625C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants, not for JANTXV-qualified parts, which retain tin-lead plating to meet MIL-STD-750 solderability and reliability standards.
What is the maximum operating temperature for JANTXV1N4625C-1/TR?
JANTXV1N4625C-1/TR supports a junction and storage temperature range of –65 °C to +175 °C. Its power dissipation must be linearly derated from 500 mW starting at 50 °C case temperature, reaching zero at 175 °C - a key design constraint for high-temperature enclosure placement.
Does JANTXV1N4625C-1/TR have low-noise performance?
Yes, JANTXV1N4625C-1/TR delivers low noise density of 2 µV/√Hz at 250 mA, verified per Microsemi's noise measurement methodology (1 kHz–3 kHz bandpass). This makes it suitable for precision analog references where noise-induced errors must remain below 10 µV RMS in bandwidth-limited applications.
How is polarity marked on JANTXV1N4625C-1/TR?
JANTXV1N4625C-1/TR uses a cathode band to indicate polarity: the banded end is the cathode and must be held positive relative to the anode to operate in Zener breakdown mode. This marking conforms to JEDEC DO-35 mechanical standards and is visible on the glass body near one lead.
