Product details
Overview
JANTXV1N4624C-1/TR from Microsemi is a 500 mW, 4.7 V ±2% tolerance, metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power supplies and precision reference circuits.
For engineers reviewing the JANTXV1N4624C-1/TR datasheet, JANTXV1N4624C-1/TR pinout, JANTXV1N4624C-1/TR application, or JANTXV1N4624C-1/TR equivalent, this part delivers stable 4.7 V regulation at 250 mA test current, low 1550 Ω dynamic impedance, 5.0 µA max reverse leakage at 3.0 V, and radiation-hardened performance suitable for mission-critical analog biasing and voltage clamping.
Technical Context
This Zener diode operates in reverse breakdown with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. Its metallurgical bond ensures mechanical robustness under thermal cycling and shock, while hermetic glass sealing maintains long-term stability in harsh environments.
The device exhibits a temperature coefficient of –0.050,+0.020 %/°C and noise density of 1 µV/√Hz at 25 °C, making it suitable for low-noise reference applications where voltage drift and broadband noise must be tightly controlled across –65 to +175 °C operating range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4624US-1/TR | Same 4.7 V ±2% spec, but in surface-mount DO-213AA package; no axial leads | Requires PCB redesign for SMT assembly; eliminates through-hole mounting | Select when automated placement and board space reduction are prioritized over legacy through-hole compatibility |
| JANTXV1N4624D-1/TR | Identical electrical specs except tighter ±1% Zener tolerance (D suffix vs C) | Used where higher initial voltage accuracy is required, e.g., calibration standards or metrology equipment | Select when absolute voltage accuracy outweighs cost sensitivity; same thermal and radiation performance |
Compared with JANTXV1N4624C-1/TR, the US-1/TR variant trades axial-leaded flexibility for SMT manufacturability, while the D-1/TR variant improves initial tolerance at no change to temperature stability or noise-enabling selection based on accuracy vs. form factor trade-offs.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4624C-1/TR?
JANTXV1N4624C-1/TR has a nominal Zener voltage of 4.7 V with a ±2% tolerance, measured at 250 mA test current and 25 °C. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0245-2 datasheet, and the "C" suffix explicitly denotes the 2% grade per the nomenclature guide on page 2.
Is JANTXV1N4624C-1/TR suitable for high-temperature operation?
Yes, JANTXV1N4624C-1/TR is rated for junction temperatures from –65 to +175 °C and is qualified to JANTXV level per MIL-PRF-19500/435. Its metallurgically bonded glass DO-35 package and thermal resistance of 250 °C/W (junction-to-lead) support reliable operation in engine bay electronics, downhole tools, and spacecraft thermal environments.
Does JANTXV1N4624C-1/TR have radiation hardness certification?
Yes, JANTXV1N4624C-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. The device's construction and materials provide resistance to total ionizing dose (TID), making it suitable for low-earth orbit and deep-space missions without additional shielding or derating.
What is the maximum reverse leakage current for JANTXV1N4624C-1/TR?
JANTXV1N4624C-1/TR has a maximum reverse leakage current (IR) of 5.0 µA at 3.0 V, as specified in the Electrical Characteristics table on page 3 of the datasheet. This low leakage supports energy-efficient biasing in battery-powered or low-quiescent-current systems.
How is polarity marked on JANTXV1N4624C-1/TR?
JANTXV1N4624C-1/TR uses a cathode band marking on the glass body to indicate polarity: the banded end is the cathode and must be held positive relative to the unbanded (anode) end for proper Zener regulation. This marking complies with JEDEC standards and is verified in the Mechanical and Packaging section on page 2.
