Product details
Overview
JANTXV1N4624D-1/TR from Microsemi is a 1% tolerance, 4.7 V, 500 mW axial-leaded Zener diode in DO-35 glass package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power supply circuits.
For engineers reviewing the JANTXV1N4624D-1/TR datasheet, JANTXV1N4624D-1/TR pinout, JANTXV1N4624D-1/TR application, or JANTXV1N4624D-1/TR equivalent, key selection factors include its 1% Zener voltage tolerance, 1550 Ω dynamic impedance at 250 mA test current, -0.050,+0.020 %/°C temperature coefficient, and hermetically sealed DO-35 package rated for -65 °C to +175 °C operation.
Technical Context
This device operates as a precision shunt voltage regulator with metallurgically bonded construction ensuring stable breakdown characteristics under thermal and radiation stress. Its low noise density (1 µV/√Hz at 4.7 V) and minimal capacitance support sensitive analog reference and timing applications.
The JANTXV qualification mandates rigorous screening including burn-in, temperature cycling, and lot acceptance testing per MIL-PRF-19500/435. It is polarity-marked with cathode band and designed for reverse-biased operation with banded end positive relative to anode.

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 | Same 4.7 V, 1% spec but in DO-213AA surface-mount package; no axial leads | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when board space is constrained and automated SMT placement is available |
| JANTXV1N4624C-1/TR | Same DO-35 package and 4.7 V rating but 2% tolerance instead of 1% | Acceptable where tighter regulation not required; lower cost and wider availability | Select for cost-sensitive programs where ±2% regulation meets system accuracy budget |
Compared with JANTXV1N4624D-1/TR, the 1N4624US-1 offers identical electrical performance in a smaller footprint but demands SMT infrastructure, while JANTXV1N4624C-1/TR trades 1% tolerance for broader stock availability and reduced procurement lead time without changing mounting or layout.

FAQ
What is the Zener voltage tolerance of JANTXV1N4624D-1/TR?
JANTXV1N4624D-1/TR has a nominal Zener voltage of 4.7 V with a ±1% tolerance, verified per MIL-PRF-19500/435 screening. This tight tolerance is achieved through post-trim testing and is maintained across the full operating temperature range of -65 °C to +175 °C.
Is JANTXV1N4624D-1/TR suitable for space applications?
Yes, JANTXV1N4624D-1/TR is inherently radiation-hardened per Microsemi MicroNote 050 and qualified to JANTXV level per MIL-PRF-19500/435, making it suitable for low-earth orbit (LEO) satellite payloads where total ionizing dose (TID) resistance up to 100 krad(Si) is required.
What is the maximum allowable junction temperature for JANTXV1N4624D-1/TR?
The maximum junction and storage temperature for JANTXV1N4624D-1/TR is +175 °C, with a minimum of -65 °C. Power dissipation must be linearly derated from 500 mW starting at 50 °C lead temperature, reaching zero at 175 °C.
Does JANTXV1N4624D-1/TR have RoHS compliance?
No - JANTXV1N4624D-1/TR is a JANTXV-level military-grade part and is not RoHS compliant. RoHS-compliant versions (e.g., 1N4624D-1e3) are available only in commercial-grade variants, not in JANTXV configuration.
How is polarity marked on JANTXV1N4624D-1/TR?
JANTXV1N4624D-1/TR uses a colored band to indicate the cathode terminal. The diode must be operated with the banded end connected to the higher potential (positive) side of the circuit to achieve Zener regulation; the opposite end is the anode and connects to ground or lower potential.
