1N4625C-1

Single Zener Diodes Overview

The Microchip Technology 1N4625C-1 is a high-reliability Zener diode designed for demanding environments. It features a nominal Zener voltage of 5.1 V with a tight tolerance of ±2%. The device operates in the DO-35 axial-leaded glass package, providing hermetic sealing for enhanced durability. It supports a maximum power dissipation of 0.5 W and functions within an extended temperature range from -65°C to +175°C. Qualified per MIL-PRF-19500/435, this component ensures stable voltage regulation for critical aerospace and defense applications.

Single Zener Diodes Procurement Notes

Verify that the specific part number suffix 'C' corresponds to the required ±2% tolerance level as documented in official specifications. Confirm compliance with relevant military qualification standards such as MIL-PRF-19500/435 before integration. Ensure procurement channels provide valid traceability documentation for high-reliability components.

Single Zener Diodes Selection Notes

Select the 1N4625C-1 when strict voltage accuracy is required alongside ruggedized packaging. The ±2% tolerance distinguishes it from standard commercial variants. Consider the DO-35 form factor for through-hole mounting constraints. Evaluate thermal management needs given the 0.5 W power rating in enclosed assemblies.

Single Zener Diodes Part Context

This component belongs to the 1N46xx series of metallurgically bonded glass Zener diodes manufactured by Microchip Technology. The series offers various voltage options and tolerance levels, including standard, improved (C suffix), and precision (D suffix) grades. These diodes are widely used in applications requiring robust performance under extreme thermal and mechanical stress.

Single Zener Diodes Replacement Considerations

Substitutes must match the 5.1 V nominal voltage, ±2% tolerance, and DO-35 hermetic package. Verify equivalent MIL-PRF-19500/435 qualification status. Ensure thermal resistance and power dissipation characteristics align with the original design parameters.
