1N4710

Overview

The Microchip Technology 1N4710 is a unidirectional silicon Zener voltage regulator diode housed in a DO-35 axial lead glass package. It features a nominal Zener voltage of 25 V with a maximum steady-state power dissipation of 500 mW at a lead temperature of 75°C or less. The device operates within a junction and storage temperature range of -65°C to +200°C, utilizing metallurgically bonded construction for reliability.

Feature Summary

• Hermetically sealed glass construction for environmental protection
• Metallurgically bonded internal structure for high reliability
• Wide operating temperature range up to 200°C

Applications

• Voltage regulation circuits
• Temperature compensated reference applications
• Overvoltage protection

Procurement Notes

Verify the specific manufacturer designation as Tak Cheong is listed in available documentation alongside the standard part number. Confirm RoHS compliance status and exact JEDEC registration ratings prior to procurement, as some series may have lower registered ratings than standard specifications.

Selection Notes

Select this component when a 25 V regulation point is required in an axial through-hole configuration. Ensure the circuit design accommodates the 500 mW power dissipation limit and derating requirements above 75°C. Verify that the 200°C maximum junction temperature aligns with the thermal environment of the target application.

Part Context

This component belongs to the standard 1N47xx series of Zener diodes, widely used for low-power voltage regulation. The DO-35 package provides a compact form factor suitable for general-purpose electronics. Microchip Technology licenses this technology from ON Semiconductor for production.

Replacement Considerations

Equivalent parts include other manufacturers' 1N4710 variants meeting the same 25 V, 500 mW, and DO-35 specifications. Cross-reference datasheets for precise tolerance and leakage current differences.
