Product details
Overview
JANTXV1N4625D-1/TR from Microsemi is a 5.1 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 axial package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4625D-1/TR datasheet, JANTXV1N4625D-1/TR pinout, JANTXV1N4625D-1/TR application, or JANTXV1N4625D-1/TR equivalent, this part delivers precise low-noise voltage reference with ±1% initial tolerance, -0.045/+0.030 %/°C tempco, and 1500 Ω dynamic impedance at 250 mA test current - critical for analog sensing, biasing, and calibration circuits requiring military-grade stability.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable output voltage across wide current (5–70 mA) and temperature (-65°C to +175°C) ranges. Its metallurgical bond ensures low thermal resistance (RθJL = 250°C/W) and radiation hardness per MicroNote 050.
Designed for hermetic axial-leaded mounting, it exhibits minimal capacitance (<1.0 pF typical at 5.1 V) and low noise density (2 µV/√Hz at IZT = 250 mA), making it suitable for precision reference and low-phase-noise oscillator biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.1 V ±1% at 250 mA - enables accurate 5 V rail regulation with tight initial accuracy. |
| Power Dissipation | 500 mW @ TL = 25°C - supports continuous operation in compact through-hole layouts with linear derating above 50°C. |
| Dynamic Impedance ZZT | 1500 Ω max at 250 mA - limits voltage shift under load transients, critical for stable reference nodes. |
| Tempco αVZ | -0.045/+0.030 %/°C - ensures <±0.5% drift over -55°C to +125°C operating range. |
| Noise Density ND | 2 µV/√Hz @ IZT - minimizes added noise in precision analog front-ends and sensor excitation circuits. |
| Reverse Leakage IR | 5.0 µA max @ 3.0 V - guarantees low standby current in battery-backed or ultra-low-power monitoring paths. |
| Package | DO-35 (DO-204AH) - standard axial glass package with cathode band marking, compatible with legacy through-hole assembly. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package: hermetically sealed, tin-lead or RoHS-compliant matte-tin plating, cathode indicated by colored band. Weight ≈ 0.2 g; lead length 25.4–38.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or lower-potential node; reverse-biased operation requires cathode at higher potential. |
| Cathode | Zener regulation terminal / voltage reference output | Banded end; connected to regulated voltage node; must be held >5.1 V relative to anode for breakdown conduction. |
Key Features
| Feature | Design Value |

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 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 available. |
| JANTXV1N4625-1/TR | Same 5.1 V, 1% tolerance, and JANTXV qualification, but uses non-RoHS tin-lead plating (no "D" suffix). | Lacks 1% tolerance; tighter voltage binning not guaranteed - may require post-screening for precision use cases. | Select only if 1% tolerance is not required and legacy tin-lead finish is mandated. |
Compared with 1N4625US-1 and JANTXV1N4625-1/TR, JANTXV1N4625D-1/TR uniquely combines 1% tolerance, JANTXV screening, and axial DO-35 packaging - making it the only option for through-hole, high-precision, radiation-tolerant reference designs requiring zero solder-joint reliability risk.

FAQ
What is the Zener voltage tolerance of JANTXV1N4625D-1/TR?
JANTXV1N4625D-1/TR has a nominal Zener voltage of 5.1 V with ±1% tolerance, indicated by the "D" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25°C ambient, and remains stable across its qualified operating temperature range of -65°C to +175°C.
Is JANTXV1N4625D-1/TR RoHS compliant?
No, JANTXV1N4625D-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS compliance (e3 suffix) is available only on commercial-grade versions; JANTXV-level parts like JANTXV1N4625D-1/TR use traditional tin-lead plating to meet MIL-STD-750 solderability requirements and mechanical reliability standards.
What is the maximum Zener current rating for JANTXV1N4625D-1/TR?
The maximum Zener current (IZM) for JANTXV1N4625D-1/TR is 70.0 mA, derived from its 500 mW power rating and 5.1 V nominal Zener voltage. This value assumes operation at 25°C lead temperature; current must be reduced linearly above 50°C per the published derating curve.
Does JANTXV1N4625D-1/TR have radiation hardness certification?
Yes, JANTXV1N4625D-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded construction and hermetic DO-35 package provide proven resilience to total ionizing dose (TID) and displacement damage, supporting use in satellite and nuclear instrumentation without additional shielding.
How is polarity marked on JANTXV1N4625D-1/TR?
JANTXV1N4625D-1/TR uses a cathode band - a single colored ring near one end of the DO-35 glass body - to indicate the cathode terminal. For proper Zener regulation, the banded end must be held at a higher potential than the opposite (anode) end; forward conduction occurs when anode is positive relative to cathode.
