Product details
Overview
JANTX1N4625-1/TR from Microsemi is a 500 mW, 5.1 V ±5% metallurgically bonded glass Zener diode in DO-35 axial package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4625-1/TR datasheet, JANTX1N4625-1/TR pinout, JANTX1N4625-1/TR application, or JANTX1N4625-1/TR equivalent, key selection factors include its 250 mA Zener test current, 1500 Ω dynamic impedance at IZT, 3.0 µA max reverse leakage at 3.8 V, -0.045/+0.030 %/°C tempco, and hermetic DO-35 package rated for -65°C to +175°C operation.
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 (IZT), exhibiting low noise density (2 µV/√Hz typical) and stable regulation across wide temperature and current ranges. Its metallurgical bond construction ensures mechanical robustness and long-term parameter stability under thermal cycling.
The JANTX1N4625-1/TR is designed for use in feedback loops of regulated DC-DC converters and reference circuits where tight voltage tolerance, low dynamic impedance, and radiation-hardened reliability are required. It maintains regulation down to 3.0 µA reverse current and supports linear derating from 500 mW at 25°C to zero at 175°C ambient.

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 electrical specs but in DO-213AA surface-mount package; no axial leads | Required for automated SMT assembly; unsuitable for through-hole prototyping or manual repair | Select when board space constraints or production automation demand SMT packaging |
| JANTXV1N4625-1 | Identical electrical parameters but qualified to higher JANTXV reliability level with extended screening | Needed for mission-critical systems requiring enhanced burn-in, life test, and lot traceability | Select when program requirements mandate JANTXV-level qualification per MIL-PRF-19500/435 |
Compared with JANTX1N4625-1/TR, the 1N4625US-1 offers identical regulation performance in a surface-mount form factor ideal for high-density layouts, while JANTXV1N4625-1 provides stricter screening and longer qualification records for systems where failure risk must be minimized beyond standard JANTX requirements.

FAQ
What is the Zener voltage tolerance for JANTX1N4625-1/TR?
JANTX1N4625-1/TR has a nominal Zener voltage of 5.1 V with a ±5% tolerance, meaning the actual measured VZ at 250 mA test current falls between 4.845 V and 5.355 V under standard test conditions per MIL-PRF-19500/435.
Is JANTX1N4625-1/TR RoHS compliant?
No, JANTX1N4625-1/TR is not RoHS compliant. The "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions (e.g., 1N4625-1e3); JANTX-level parts retain tin-lead plating per MIL-STD-750 for solderability and reliability in high-reliability applications.
What is the maximum reverse leakage current for JANTX1N4625-1/TR?
JANTX1N4625-1/TR specifies a maximum reverse leakage current (IR) of 3.0 µA at VR = 3.8 V, measured at 25°C. This low leakage ensures minimal power loss in standby regulation circuits and preserves accuracy in high-impedance feedback paths.
Can JANTX1N4625-1/TR be used in surface-mount designs?
No, JANTX1N4625-1/TR uses the axial-leaded DO-35 package and requires through-hole mounting. For surface-mount equivalents, consider the 1N4625US-1 in DO-213AA package - it shares identical electrical characteristics but is not JANTX-qualified.
What is the thermal resistance junction-to-lead for JANTX1N4625-1/TR?
JANTX1N4625-1/TR has a thermal resistance junction-to-lead (RθJL) of 250°C/W when mounted with 3/8 inch (10 mm) lead length from body. This value is critical for calculating junction temperature rise under load and must be applied with appropriate derating above 50°C lead temperature.
