Product details
Overview
JANTXV1N4621D-1/TR from Microsemi is a 1% tolerance, 3.6 V, 500 mW axial-leaded Zener diode in DO-35 (DO-204AH) glass package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4621D-1/TR datasheet, JANTXV1N4621D-1/TR pinout, JANTXV1N4621D-1/TR application, or JANTXV1N4621D-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status required for precision analog reference and regulated bias design.
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded construction for low-noise, stable regulation across -65 °C to +175 °C. Its 3.6 V nominal Zener voltage exhibits a temperature coefficient of -0.065 %/°C and dynamic impedance of 1700 Ω at 250 mA test current.
Designed for hermetic axial-leaded mounting, it delivers 1 µV/√Hz noise density at 3.6 V and supports up to 83 mA maximum Zener current under 500 mW derated power dissipation - enabling use in low-drift analog circuits where ESD immunity and radiation hardness are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4621US-1/TR | Same electrical specs but in surface-mount DO-213AA package; no axial leads | Requires SMT reflow process instead of through-hole insertion; unsuitable for manual prototyping or high-vibration mechanical retention | Select when board space is constrained and automated assembly is available |
| JANTXV1N4621C-1/TR | Identical package and qualification level but 2% Zener tolerance (C suffix) instead of 1% | Acceptable where tighter voltage tolerance is not required for cost-sensitive designs | Select when ±2% regulation meets system accuracy requirements and reduces procurement cost |
Compared with JANTXV1N4621D-1/TR, the US variant offers footprint reduction at the expense of mechanical robustness and hand-soldering compatibility, while the C-suffix version trades 1% tolerance for lower unit cost - both require explicit validation of thermal derating and layout clearance in high-reliability deployments.

FAQ
What is the Zener voltage tolerance of JANTXV1N4621D-1/TR?
JANTXV1N4621D-1/TR has a nominal Zener voltage of 3.6 V with ±1% tolerance, indicated by the "D" suffix in its part number per Microsemi's nomenclature. This tolerance is guaranteed at 25 °C with 250 mA test current and applies across the full military temperature range when derated per the power curve. The 1% tolerance enables direct use in precision analog references without external trimming.
Is JANTXV1N4621D-1/TR qualified to MIL-PRF-19500/435?
Yes, JANTXV1N4621D-1/TR is qualified to MIL-PRF-19500/435 at the JANTXV reliability level, as confirmed in Microsemi document T4-LDS-0245-2. This qualification includes screening for temperature cycling, mechanical shock, vibration, and burn-in - ensuring suitability for high-reliability aerospace and defense applications where failure modes must be rigorously controlled.
What is the maximum Zener current for JANTXV1N4621D-1/TR?
The maximum Zener current (IZM) for JANTXV1N4621D-1/TR is 83.0 mA, derived from its 500 mW power rating and 3.6 V Zener voltage. This value assumes operation at 25 °C lead temperature; actual usable current must be reduced per the linear derating curve starting at 50 °C ambient or lead temperature, reaching zero at 175 °C.
Does JANTXV1N4621D-1/TR have low-noise performance?
Yes, JANTXV1N4621D-1/TR delivers 1 µV/√Hz noise density at its 3.6 V Zener voltage, measured at 25 °C with a 1–3 kHz bandpass filter. This low noise is enabled by metallurgical bonding and optimized junction design, making JANTXV1N4621D-1/TR suitable for precision analog circuits such as sensor excitation, reference buffers, and low-level signal conditioning where noise contribution must be minimized.
What package type does JANTXV1N4621D-1/TR use?
JANTXV1N4621D-1/TR uses the DO-35 (also designated DO-204AH) axial-leaded, hermetically sealed glass package. It features tin-lead or RoHS-compliant matte-tin plating, cathode band marking, and weighs approximately 0.2 grams. The package dimensions comply with MIL-STD-1835 and support manual or automated through-hole assembly.
