Product details
Overview
JANTXV1N4620D-1/TR from Microsemi is a 1% tolerance, 3.3 V, 500 mW axial-leaded Zener diode in DO-35 glass package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power conditioning circuits.
For engineers reviewing the JANTXV1N4620D-1/TR datasheet, JANTXV1N4620D-1/TR pinout, JANTXV1N4620D-1/TR application, or JANTXV1N4620D-1/TR equivalent, key selection criteria include Zener voltage tolerance (1%), dynamic impedance (1650 Ω), noise density (1 µV/√Hz), thermal resistance (250 °C/W), and JANTXV-level qualification for extended temperature operation.
Technical Context
This device operates as a precision shunt voltage regulator with metallurgically bonded construction ensuring stable breakdown characteristics across -65 °C to +175 °C. Its low noise density (1 µV/√Hz at 3.3 V) and tight 1% Zener voltage tolerance support low-noise reference applications in analog signal chains and sensor excitation circuits.
The DO-35 package provides hermetic sealing and axial-leaded mounting compatible with through-hole PCB assembly. Thermal resistance junction-to-lead is 250 °C/W at 3/8″ lead length, enabling reliable 500 mW power dissipation when properly heatsunk in high-reliability environments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4620US-1/TR | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Requires SMT reflow process instead of through-hole soldering; unsuitable for manual prototyping or high-vibration mechanical retention. | Select when board space is constrained and automated assembly is used. |
| JANTXV1N4620C-1/TR | Identical construction and package, but 2% Zener voltage tolerance instead of 1%. | Lower cost alternative where ±66 mV regulation error is acceptable versus ±33 mV for JANTXV1N4620D-1/TR. | Select when tighter tolerance is not required to reduce procurement cost without sacrificing reliability grade. |
Compared with JANTXV1N4620D-1/TR, the US variant trades axial-leaded mechanical robustness for SMT footprint efficiency, while the C variant retains identical form factor and reliability but relaxes voltage tolerance-enabling cost-sensitive or space-constrained alternatives without compromising JANTXV qualification.

JANTXV1N4620D-1/TR is rated for 500 mW average power dissipation at 25 °C case temperature. Power must be linearly derated starting at 50 °C lead temperature, reaching zero at 175 °C. On a typical FR4 PCB with 4 mm² copper pads, derating begins at 25 °C ambient, supporting JANTXV1N4620D-1/TR in thermally demanding environments when properly heatsunk.
Does JANTXV1N4620D-1/TR have low noise performance?
Yes, JANTXV1N4620D-1/TR exhibits a noise density of 1 µV/√Hz at its 3.3 V Zener voltage and 250 mA test current. This low noise characteristic is confirmed per Microsemi MicroNote 202 and makes JANTXV1N4620D-1/TR appropriate for precision analog circuits such as high-resolution ADC references and low-jitter sensor excitation sources.
What package type does JANTXV1N4620D-1/TR use?
JANTXV1N4620D-1/TR uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package. It features tin-lead or RoHS-compliant matte-tin plating, cathode identification via a colored band, and weighs approximately 0.2 grams.
