1N4764A-TAP

Overview

The 1N4764A-TAP is a single silicon planar Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 100 V with a tolerance of ±5% and a maximum power dissipation of 1.3 W. The device utilizes a DO-204AL (DO-41) axial through-hole package. Key electrical parameters include a maximum Zener impedance of 350 Ohms, a forward voltage of 1.2 V at 200 mA, and a reverse leakage current of 5 µA at 76 V. It supports a junction temperature up to 175°C and holds AEC-Q101 automotive qualification.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation in high-power applications
• Provides precise voltage clamping with standard ±5% tolerance
• Designed for stabilization and clipping circuits requiring robust thermal performance

Applications

• Voltage stabilization circuits
• Signal clipping applications
• Automotive electronic systems

Procurement Notes

Verify the specific suffix TAP corresponds to tape-and-reel packaging when ordering. Confirm AEC-Q101 qualification status if automotive compliance is required. Ensure the DO-204AL package dimensions match the target PCB layout. Cross-reference the manufacturer part number against official Vishay documentation to confirm current production status and availability.

Selection Notes

Select this component for designs requiring a 100 V reference or protection level within a 1.3 W power budget. The DO-41 package suits through-hole assembly processes. Consider the 350 Ohm impedance value for dynamic regulation requirements. Verify that the 175°C junction temperature rating aligns with the operational thermal environment of the final equipment.

Part Context

This part belongs to the 1N47xxA series of power Zener diodes from Vishay. The series covers a wide voltage range from 3.3 V to 100 V. These diodes are widely used in industrial and automotive electronics due to their reliability and standardized DO-41 footprint. The 'A' suffix typically denotes tighter tolerance specifications compared to non-suffixed variants.
