1N4625C-1/TR

Overview

The Microchip Technology 1N4625C-1/TR is a low-noise Zener diode with a nominal voltage of 5.1 V and a power dissipation rating of 500 mW. It features a tight voltage tolerance of ±2%, indicated by the 'C' suffix, and operates within a temperature range of -65°C to +175°C. The device utilizes a DO-35 axial glass package and is supplied in tape-and-reel format for automated surface-mount or through-hole assembly processes.

Feature Summary

• Hermetically sealed glass construction for environmental protection
• Low noise characteristics suitable for sensitive signal applications
• Tight voltage tolerance for precise regulation requirements

Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• Low-noise power supply regulation

Procurement Notes

Verify the specific manufacturer source, as the JANS/JANTX prefixes often denote military-grade variants from Cobham PLC rather than standard Microchip production. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies significantly between commercial and qualified aerospace grades.

Selection Notes

Select this component when a stable 5.1 V reference with high precision is required. The ±2% tolerance ensures tighter regulation than standard 5% parts. Ensure the system design accommodates the thermal resistance and operating temperature limits specified for the DO-35 glass package.

Part Context

This part belongs to the 1N4625 series of low-noise Zener diodes. The '-1' suffix typically indicates a metallurgically bonded die for enhanced reliability, while the 'C' suffix specifies the 2% voltage tolerance. The '/TR' designation confirms the tape-and-reel packaging format.

Replacement Considerations

JANTX1N4625C-1 offers equivalent electrical specifications with potentially different manufacturing origin. JAN1N4625D-1 provides similar performance with 1% tolerance. Verify pinout compatibility and package dimensions before substitution.
