Product details
Overview
JANTX1N4625C-1/TR from Microsemi is a 5.1 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4625C-1/TR datasheet, JANTX1N4625C-1/TR pinout, JANTX1N4625C-1/TR application, or JANTX1N4625C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), noise density (2 µV/√Hz), dynamic impedance (1500 Ω), junction temperature range (–65 °C to +175 °C), and MIL-qualified reliability level.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 5.1 V at 250 mA test current, exhibiting low noise density (2 µV/√Hz) and moderate dynamic impedance (1500 Ω). Its metallurgical bond construction ensures stable regulation across wide current and temperature ranges.
Designed for military-grade applications, it supports operation from –65 °C to +175 °C, with thermal resistance junction-to-lead of 250 °C/W at 10 mm lead length and linear power derating from 500 mW at 25 °C to zero at 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.1 V ±2% at 250 mA - enables precise reference generation in analog circuits requiring tight voltage stability. |
| Power Dissipation | 500 mW at 25 °C - supports continuous regulation in compact, unheatsinked designs with linear derating above 50 °C. |
| Dynamic Impedance ZZT | 1500 Ω max at 250 mA - determines output voltage variation under load transients; lower values improve regulation fidelity. |
| Noise Density | 2 µV/√Hz - critical for low-noise references in precision instrumentation and ADC/DAC biasing. |
| Reverse Leakage IR | 3.0 µA max at 3.0 V - ensures minimal parasitic current draw in standby or high-impedance sensing nodes. |
| Temp Coefficient αVZ | –0.045 to +0.030 %/°C - defines voltage drift over temperature; enables compensation in wide-range environments. |
| Junction Temp Range | –65 °C to +175 °C - qualifies for extreme-environment deployment in avionics, downhole tools, and space-qualified systems. |

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, ±2% spec but in DO-213AA surface-mount package; no axial leads. | Used where PCB real estate is constrained and reflow assembly required; lacks axial mounting flexibility. | Select when automated SMT production is mandatory and thermal path differs (RθJL not defined). |
| JAN1N4625C-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTX). | Suitable for less demanding military programs where full JANTX burn-in and lot acceptance tests are not mandated. | Choose for cost-sensitive defense subsystems meeting JAN-level reliability requirements. |
Compared with JANTX1N4625C-1/TR, the 1N4625US-1 enables board-space savings and SMT compatibility but sacrifices axial mounting versatility and MIL-qualified thermal derating data; the JAN1N4625C-1 offers identical form-fit-function at lower reliability assurance and cost.

FAQ
What is the Zener voltage tolerance of JANTX1N4625C-1/TR?
JANTX1N4625C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This means its nominal 5.1 V Zener voltage is guaranteed between 4.998 V and 5.202 V at 250 mA test current and 25 °C ambient, supporting tighter regulation than standard ±5% variants.
Is JANTX1N4625C-1/TR RoHS compliant?
No, JANTX1N4625C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (suffix "e3") are available only for commercial-grade parts, not for MIL-qualified JANTX-level devices like JANTX1N4625C-1/TR, which retain tin-lead plating for solderability and reliability in high-reliability applications.
What is the maximum Zener current IZM for JANTX1N4625C-1/TR?
The maximum Zener current IZM for JANTX1N4625C-1/TR is 70.0 mA, derived from its 500 mW power rating and 5.1 V nominal Zener voltage (P = V × I → I = 0.5 W / 5.1 V ≈ 98 mA), but limited by thermal constraints and specified as 70.0 mA in the Electrical Characteristics table to ensure safe operation within junction temperature limits.
How does the temperature coefficient affect JANTX1N4625C-1/TR in wide-temperature applications?
JANTX1N4625C-1/TR has a temperature coefficient αVZ of –0.045 to +0.030 %/°C, meaning its Zener voltage may drift up to ±0.038 V over a 100 °C range. This low-drift behavior enables stable reference generation in avionics and downhole tools without external compensation, unlike higher-coefficient Zeners that require trimming networks.
Can JANTX1N4625C-1/TR be used as a substitute for commercial 1N4625 diodes?
JANTX1N4625C-1/TR shares identical electrical parameters (5.1 V, ±2%, 1500 Ω ZZT) with commercial 1N4625C-1, but adds MIL-PRF-19500/435 JANTX qualification including enhanced screening, lot traceability, and extended temperature validation. It is a drop-in functional replacement where military reliability is required, though not interchangeable in commercial-only BOMs due to qualification overhead.
