Overview
JANTXV1N4620C-1 from Microsemi is a 500 mW, 3.3 V Zener diode in DO-35 glass package with 2% voltage tolerance, metallurgically bonded construction, and MIL-PRF-19500/435 JANTXV qualification for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4620C-1 datasheet, JANTXV1N4620C-1 pinout, JANTXV1N4620C-1 application, or JANTXV1N4620C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), thermal resistance (250 °C/W junction-to-lead), and hermetic DO-35 packaging for stable operation across -65 to +175 °C.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 3.3 V at 250 mA test current, exhibiting dynamic impedance of 1650 Ω and reverse leakage ≤3.5 µA at 2.5 V. Its metallurgical bond ensures low noise and radiation hardness per MicroNote 050.
Designed for high-reliability environments, JANTXV1N4620C-1 maintains regulation over wide current (0.25–85 mA) and temperature (-65 to +175 °C) ranges, with temperature coefficient of +0.075 %/°C and maximum rated power dissipation of 500 mW at 25 °C, derating linearly to zero at 175 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4620D-1 | 1% Zener voltage tolerance vs. 2% for JANTXV1N4620C-1; identical package, power rating, and qualification level | Required where tighter initial accuracy is needed for calibration-critical references | Select JANTXV1N4620D-1 only if system-level calibration budget demands <±1% absolute error at 25 °C |
| 1N4620US-1 | Same electrical specs but in DO-213AA surface-mount package; no MIL qualification; commercial-only RoHS compliance | Suitable for cost-sensitive, non-military PCBs where board space is constrained and radiation hardness is not required | Choose 1N4620US-1 for commercial industrial designs needing footprint reduction and simplified assembly, not mission-critical reliability |
Compared with JANTXV1N4620C-1, JANTXV1N4620D-1 offers higher initial accuracy at same reliability grade, while 1N4620US-1 trades qualification and radiation tolerance for SMT compatibility and lower cost-neither is pin-compatible due to differing packages.

FAQ
What is the Zener voltage tolerance of JANTXV1N4620C-1?
JANTXV1N4620C-1 has a nominal Zener voltage of 3.3 V with a tolerance of ±2%, as indicated by the "C" 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 temperature range of -65 to +175 °C.
Is JANTXV1N4620C-1 suitable for high-temperature applications?
Yes, JANTXV1N4620C-1 is fully rated for operation from -65 to +175 °C junction temperature and is qualified to MIL-PRF-19500/435 JANTXV level. Its metallurgically bonded DO-35 glass package and thermal resistance of 250 °C/W (junction-to-lead) support reliable performance in downhole, engine bay, and avionics environments.
Does JANTXV1N4620C-1 have radiation hardness certification?
JANTXV1N4620C-1 is inherently radiation hard per Microsemi MicroNote 050, with documented tolerance to total ionizing dose (TID) relevant to space and nuclear applications. While not individually certified to a specific rad level, its construction and qualification history support use in radiation-prone environments up to 100 krad(Si).
What is the maximum Zener current IZM for JANTXV1N4620C-1?
The maximum Zener current IZM for JANTXV1N4620C-1 is 85 mA, derived from its 500 mW power rating and 3.3 V Zener voltage (IZM = PM(AV)/VZ). This value assumes operation at 25 °C lead temperature; current must be reduced per the linear derating curve above 50 °C.
How is polarity marked on JANTXV1N4620C-1?
JANTXV1N4620C-1 uses a cathode band marking on the glass body to indicate polarity. The banded end is the cathode and must be held positive with respect to the anode for proper Zener regulation. This marking complies with JEDEC DO-35 standards and is visible under standard visual inspection.
