1N4764A-T

Overview

The 1N4764A-T is a single silicon planar Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It provides a nominal Zener voltage of 100 V with a tolerance of ±5%. The device features a maximum power dissipation of 1.3 W and operates within a junction temperature range up to 175°C. It utilizes the DO-204AL (DO-41) axial through-hole package. Key electrical characteristics include a maximum Zener impedance of 3000 Ohms, a forward voltage of 1.2 V at 200 mA, and a reverse leakage current of 5 µA at 76 V.

Feature Summary

• Single unidirectional voltage regulation using planar silicon technology
• High thermal stability supporting operation up to 175°C junction temperature
• Robust mechanical construction in an axial leaded glass passivated package

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection for sensitive electronic components
• Clamping applications in power supply outputs

Procurement Notes

Verify the specific suffix 'T' against official Vishay documentation to confirm tape-and-reel packaging specifications, as this variant differs from standard bulk or cut-tape options. Ensure the component meets AEC-Q101 automotive qualification requirements if intended for automotive-grade assemblies. Cross-reference datasheet revisions to confirm compliance with RoHS3 standards and current environmental regulations before finalizing procurement orders.

Selection Notes

Select this component when a 100 V regulation point is required in a through-hole design. The 1.3 W power rating allows for higher current handling compared to lower-power variants. Consider the high Zener impedance value for applications where precise dynamic resistance is not critical. Verify that the axial lead form factor fits the target PCB layout constraints.

Part Context

This part belongs to the 1N47xx series of general-purpose Zener diodes produced by Vishay. These devices are widely used in industrial and consumer electronics for basic voltage regulation tasks. The 1N4764A variant specifically targets the 100 V segment of this extensive portfolio, offering a balance between voltage capability and power dissipation in a standard axial package.

Replacement Considerations

Compatible substitutes include the 1N4764A-TR and 1N4764A-TAP from Vishay, which share identical electrical specifications but differ in packaging format. Other manufacturers producing JEDEC-compliant 1N4764A equivalents may be considered if pinout and thermal characteristics match.
