Product details
Overview
JANTX1N4620C-1/TR from Microsemi is a 500 mW, 3.3 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JANTX reliability level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 1650 Ω dynamic impedance at 250 mA test current, and 3.5 µA maximum reverse leakage at 1.5 V. It delivers stable reference voltage in precision analog power supplies and military-grade voltage clamping circuits.
For engineers reviewing the JANTX1N4620C-1/TR datasheet, JANTX1N4620C-1/TR pinout, JANTX1N4620C-1/TR application, or JANTX1N4620C-1/TR equivalent, this page provides verified Zener voltage, temperature coefficient, noise density, power derating behavior, and MIL-spec qualification details essential for high-reliability analog design and aerospace power conditioning.
Technical Context
This device operates as a reverse-biased Zener regulator with metallurgically bonded junction for enhanced thermal stability and radiation hardness. Its 3.3 V nominal Zener voltage is specified at 250 mA test current (IZT), with dynamic impedance of 1650 Ω measured under 10% rms AC modulation superimposed on IZT.
The diode exhibits a temperature coefficient of –0.075 %/°C and maximum noise density of 1 µV/√Hz at its rated Zener voltage, supporting low-noise reference applications. Power dissipation linearly derates from 500 mW at 25 °C ambient to zero at 175 °C junction temperature.

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 electrical specs but in surface-mount DO-213AA package; no axial leads | Used where board space is constrained and reflow assembly is preferred over through-hole | Select when automated SMT placement is required and thermal mass constraints allow for lower RθJA (200 °C/W vs. 250 °C/W) |
| JANTXV1N4620C-1/TR | Identical electrical parameters but qualified to JANTXV level with extended screening and tighter parametric limits | Required for mission-critical subsystems where burn-in, life test, and radiation testing are mandated | Choose only when system-level qualification demands JANTXV-level reliability beyond JANTX baseline |
Compared with JANTX1N4620C-1/TR, the 1N4620US-1/TR offers identical regulation performance in a smaller footprint but requires PCB layout adaptation, while JANTXV1N4620C-1/TR adds cost and lead time for enhanced screening without changing core Zener behavior-making JANTX the optimal balance for most high-reliability programs.

FAQ
What is the Zener voltage tolerance for JANTX1N4620C-1/TR?
JANTX1N4620C-1/TR has a nominal Zener voltage of 3.3 V with ±2% tolerance, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is guaranteed over the full operating temperature range (–65 to +175 °C) and applies at the specified 250 mA test current (IZT). The device meets MIL-PRF-19500/435 requirements for JANTX-level screening.
Does JANTX1N4620C-1/TR require heatsinking in typical applications?
JANTX1N4620C-1/TR does not require external heatsinking in standard applications dissipating ≤500 mW at 25 °C ambient, thanks to its DO-35 package thermal resistance of 250 °C/W (junction-to-lead). However, power must be linearly derated above 50 °C lead temperature, reaching zero at 175 °C. For sustained 500 mW operation, ensure ≥3/8″ (10 mm) lead length from body and adequate copper pad area per Microsemi's FR4 board guidelines.
Is JANTX1N4620C-1/TR RoHS compliant?
No, JANTX1N4620C-1/TR is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4620C-1e3); JANTX-level parts retain traditional tin-lead plating to meet MIL-STD-750 solderability and reliability requirements. RoHS compliance is explicitly excluded from JANTX, JANTXV, and JANS qualified devices per Microsemi documentation.
What is the maximum reverse leakage current for JANTX1N4620C-1/TR?
JANTX1N4620C-1/TR has a maximum reverse leakage current (IR) of 3.5 µA at 1.5 V reverse voltage, per the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This value is measured at 25 °C and reflects the diode's low-leakage performance critical for high-impedance reference and sensing applications where quiescent current must be minimized.
How is polarity marked on JANTX1N4620C-1/TR?
JANTX1N4620C-1/TR uses a cathode band to indicate polarity: the banded end is the cathode and must be connected to the higher-potential side of the circuit during Zener regulation. When used as a shunt regulator, the cathode connects to the unregulated input rail and the anode to ground or the regulated node. This marking conforms to JEDEC DO-35 mechanical standards and is verified in Microsemi's Mechanical and Packaging section.
