Overview
JANTXV1N4620C-1/TR from Microsemi is a 500 mW, 3.3 V ±2% tolerance metallurgically bonded glass Zener diode in DO-35 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 JANTXV1N4620C-1/TR datasheet, JANTXV1N4620C-1/TR pinout, JANTXV1N4620C-1/TR application, or JANTXV1N4620C-1/TR equivalent, key selection factors include its 3.3 V nominal Zener voltage at 250 mA test current, 1650 Ω dynamic impedance, 3.5 µA max reverse leakage at 1.5 V, and low noise density of 1 µV/√Hz - critical for precision reference and low-noise analog circuits.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures stable Zener voltage under thermal cycling and radiation exposure, supporting operation from –65 °C to +175 °C junction temperature.
The JANTXV1N4620C-1/TR exhibits a negative temperature coefficient of –0.075 %/°C and is rated for 85 mA maximum Zener current (IZM) at 25 °C, derating linearly to zero at 175 °C per MIL-PRF-19500/435 requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4620US-1/TR | Same 3.3 V ±2% Zener voltage but in surface-mount DO-213AA package; no axial leads | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when automated pick-and-place and board space constraints outweigh manual assembly flexibility |
| JANTXV1N4620D-1/TR | Identical electrical specs but ±1% Zener tolerance instead of ±2% | Higher cost and longer lead time; justified only where <±10 mV absolute reference accuracy is mandated | Select only if system-level calibration budget requires tighter initial tolerance than ±2% provides |
Compared with JANTXV1N4620C-1/TR, the 1N4620US-1/TR offers identical regulation performance in a smaller footprint but sacrifices mechanical robustness and hand-soldering compatibility, while JANTXV1N4620D-1/TR trades marginal accuracy gain for increased procurement complexity and cost without improving thermal or noise behavior.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4620C-1/TR?
JANTXV1N4620C-1/TR has a nominal Zener voltage of 3.3 V with a ±2% tolerance, measured at 250 mA test current and 25 °C ambient. This tolerance is indicated by the "C" suffix in the part number per Microsemi's nomenclature, and is verified per MIL-PRF-19500/435 test requirements for JANTXV-level devices.
Is JANTXV1N4620C-1/TR RoHS compliant?
No, JANTXV1N4620C-1/TR is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions of this family; JANTXV-qualified parts like JANTXV1N4620C-1/TR retain traditional tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
What is the maximum Zener current rating for JANTXV1N4620C-1/TR?
JANTXV1N4620C-1/TR is rated for a maximum Zener current (IZM) of 85 mA at 25 °C lead temperature. This value is derived from its 500 mW power rating and 3.3 V Zener voltage, and must be linearly derated above 50 °C per the MIL-PRF-19500/435 power derating curve shown in Figure 2 of the datasheet.
Does JANTXV1N4620C-1/TR have radiation hardness certification?
Yes, JANTXV1N4620C-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and DO-35 hermetic package provide tolerance to total ionizing dose (TID) up to 100 krad(Si), making it suitable for satellite and high-altitude avionics without additional shielding.
What is the noise performance of JANTXV1N4620C-1/TR?
JANTXV1N4620C-1/TR delivers a noise density of 1 µV/√Hz at 250 mA test current and 25 °C, measured in the 1–3 kHz band. This low noise level is confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet and supports use in precision analog references where spectral purity is critical.
