1N4764A B0G

Overview

The 1N4764A B0G is a silicon planar Zener diode manufactured by Taiwan Semiconductor Corporation. It provides voltage regulation with a nominal breakdown voltage of 100V and a tolerance of ±5%. The device is housed in the DO-204AL (DO-41) axial leaded package, designed for through-hole mounting. It features a maximum DC power dissipation of 1W at 25°C ambient temperature. The component utilizes a glass passivated junction to ensure stability and reliability under various operating conditions.

Feature Summary

• Utilizes silicon planar technology for consistent electrical performance
• Features a glass passivated junction for enhanced environmental stability
• Provides precise voltage regulation within specified tolerance limits

Applications

• Voltage reference circuits requiring stable 100V levels
• Overvoltage protection stages in power supply designs
• Clipping and waveform shaping applications

Procurement Notes

Verify the specific suffix 'B0G' against official Taiwan Semiconductor documentation to confirm exact manufacturing lot codes or specific packaging variations. Ensure compatibility with standard DO-41 footprint requirements during procurement planning. Cross-reference datasheet revisions to confirm current RoHS compliance status and material declarations before finalizing orders.

Selection Notes

Select this component when a 100V Zener voltage with tight ±5% tolerance is required in an axial package. Consider the 1W power rating and thermal resistance characteristics relative to the application's heat dissipation capabilities. Verify that the DO-41 form factor fits the target PCB layout constraints compared to surface mount alternatives.

Part Context

This part belongs to the 1N47xx series of 1-watt Zener diodes, widely used for general-purpose voltage regulation. The 'A' suffix typically denotes the ±5% tolerance variant, while the base number indicates the specific voltage rating. Taiwan Semiconductor produces this series using planar technology for improved consistency over older junction types.

Replacement Considerations

Equivalent parts include the 1N4764A from other manufacturers such as Microchip or ON Semiconductor, provided they meet the same 100V, 1W, and ±5% specifications in a DO-41 package. Verify pinout orientation and thermal characteristics match the original design requirements.
