1N4764A-TR

Overview

The 1N4764A-TR is a single Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 100 V with a tolerance of ±5%. The device has a maximum power dissipation of 1.3 W and is housed in the DO-204AL (DO-41) axial through-hole package. Key electrical parameters include a maximum Zener impedance (Zzt) of 350 Ohms and a reverse leakage current of 5 µA at 76 V. The forward voltage is 1.2 V at 200 mA, and it supports a junction temperature up to 175°C.

Feature Summary

• Provides stable voltage regulation at a nominal 100 V level with tight manufacturing tolerances.
• Engineered for high thermal stability with a maximum junction temperature rating of 175°C.
• Constructed in a robust DO-204AL axial leaded package suitable for through-hole mounting.

Applications

• Voltage reference circuits requiring precise 100 V standards
• Overvoltage protection stages in high-voltage systems
• Clamping applications in industrial control equipment

Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging when sourcing. Confirm AEC-Q101 automotive qualification status if required for your application. Ensure the DO-204AL package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component for designs needing a 100 V Zener voltage with 1.3 W power handling. Consider the 350 Ohm impedance value for noise-sensitive applications. Verify that the through-hole DO-204AL package fits your assembly constraints compared to surface-mount alternatives.

Part Context

This part belongs to the 1N47xxA series of Zener diodes from Vishay. These components are widely used in general-purpose electronic circuits for voltage regulation and protection. The 1N4764A variant specifically targets higher voltage applications within this standard series lineup.

Replacement Considerations

Check for equivalent parts from other manufacturers offering 100 V, 1.3 W Zener diodes in DO-41 packages. Ensure any substitute matches the ±5% tolerance and 175°C thermal rating. Verify pinout compatibility for direct replacement in existing designs.
