1N4764AH

Single Zener Diodes Overview

The 1N4764AH is a silicon planar Zener diode manufactured by Taiwan Semiconductor, designed for voltage regulation applications. It features a nominal Zener voltage of 100V with a tolerance of ±5% and a maximum power dissipation of 1W. The device is housed in the DO-204AL (DO-41) axial leaded package, suitable for through-hole mounting. It is qualified under the AEC-Q101 standard for automotive electronics reliability. Key electrical characteristics include a maximum reverse leakage current of 5µA at 76V and a test current of 3.3mA.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Qualified for automotive environments via AEC-Q101 certification
• Encapsulated in a hermetically sealed glass DO-41 package

Single Zener Diodes Applications

• Automotive electronic circuit protection
• Voltage reference circuits in automotive systems
• Overvoltage protection in vehicle power supplies

Single Zener Diodes Procurement Notes

Verify the specific suffix 'AH' against the manufacturer's official datasheet to confirm it denotes the AEC-Q101 qualified automotive grade variant. Ensure the ordering documentation explicitly references the Taiwan Semiconductor part number 1N4764AH to distinguish it from non-automotive equivalents like the 1N4764A. Confirm RoHS compliance status as indicated in the product specifications.

Single Zener Diodes Selection Notes

Select this component when an automotive-grade Zener diode with a 100V breakdown voltage is required. The 1N4764AH offers a balance of high voltage capability and robust reliability standards. Consider the 1W power rating and DO-41 package constraints during thermal management and PCB layout planning. Verify that the 5% tolerance meets the precision requirements of the target application.

Single Zener Diodes Part Context

This component belongs to the 1N47xxA series of 1-watt Zener diodes produced by Taiwan Semiconductor. The 'A' suffix typically indicates a tighter voltage tolerance compared to standard variants. The 'H' suffix often designates specific packaging or qualification levels, such as automotive readiness, within the manufacturer's portfolio.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 100V Zener voltage, 1W power rating, and DO-41 package. Automotive applications require components with equivalent AEC-Q101 qualification. Generic 1N4764A parts may lack the specific automotive screening unless verified.
