Product details

Overview

JANTXV1N4624C-1 from Microsemi is a 500 mW, 4.7 V ±2% metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies, reference circuits, and overvoltage protection.

For engineers reviewing the JANTXV1N4624C-1 datasheet, JANTXV1N4624C-1 pinout, JANTXV1N4624C-1 application, or JANTXV1N4624C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (1550 Ω @ 250 mA), noise density (1 µV/√Hz), temperature coefficient (−0.050,+0.020 %/°C), and JANTXV-level qualification for extended temperature and radiation-hardened operation.

Technical Context

This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 4.7 V at 250 mA test current, exhibiting low noise density (1 µV/√Hz) and a tightly controlled temperature coefficient range of −0.050 to +0.020 %/°C. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and mechanical stress.

The JANTXV1N4624C-1 is rated for 500 mW average power dissipation at 25 °C, with linear derating to zero at 175 °C junction temperature and a maximum reverse leakage current of 3.0 µA at 3.0 V. It features hermetically sealed axial-leaded DO-35 (DO-204AH) packaging compliant with MIL-STD-750 solderability requirements.

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 Zener voltage (4.7 V) and tolerance (±2%), but in surface-mount DO-213AA package; no JANTXV qualification.	Lacks MIL-PRF-19500 screening; suitable only for commercial/industrial SMT designs where radiation hardness and extended temperature are not required.	Select when board space is constrained and high-reliability qualification is unnecessary.
JANTXV1N4624-1	Identical electrical specs and JANTXV qualification, but ±5% Zener voltage tolerance instead of ±2% (C suffix).	Higher voltage variation requires tighter system-level calibration; less suitable for precision reference applications.	Select only if cost sensitivity outweighs need for tight voltage tolerance in non-critical regulation tasks.

Compared with JANTXV1N4624C-1, the JANTXV1N4624-1 offers identical reliability and thermal performance but sacrifices 2% tolerance for lower cost, while the 1N4624US-1 trades qualification and axial mounting for SMT compatibility-neither is pin-compatible due to differing packages and screening levels.
