1N4764AHB0G

Overview

The 1N4764AHB0G is a silicon planar Zener diode manufactured by Taiwan Semiconductor Corporation, designed for voltage regulation and clipping applications. It features a hermetically sealed glass DO-204AL (DO-41) axial leaded package suitable for automated assembly processes. The device provides a nominal Zener voltage of 91 V with a standard tolerance of ±5%. It is rated for a maximum power dissipation of 1 W at an ambient temperature of 25°C. The component operates within a junction temperature range of -55°C to 150°C and meets AEC-Q101 automotive qualification standards.

Feature Summary

• Hermetically sealed glass construction ensures reliability in harsh environments
• Automotive grade qualification compliant with AEC-Q101 standards
• Planar die technology supports high-reliability automated assembly

Applications

• Voltage regulation in automotive electronic circuits
• Clipping and protection circuits requiring stable reference voltages
• Power supply systems demanding high thermal stability

Procurement Notes

Verify the specific suffix HB0G against official datasheets to confirm the exact tolerance and packaging configuration. Ensure compatibility with existing PCB footprints for the DO-204AL package. Confirm RoHS compliance status and manufacturing origin requirements before finalizing procurement orders.

Selection Notes

Select this component when a 91 V Zener voltage is required in an axial through-hole package. The ±5% tolerance offers tighter regulation than standard ±10% variants. Consider the 1 W power rating and thermal resistance characteristics for heat dissipation needs in the target application circuit.

Part Context

This part belongs to the 1N4763 series of 1 Watt Zener diodes produced by Taiwan Semiconductor Corporation. The series covers a wide voltage range from 3.3 V to 100 V. The 1N4764 variant specifically targets the 91 V segment, providing a standardized solution for mid-range voltage regulation tasks in industrial and automotive sectors.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4764A parts in DO-41 packages. Verify electrical parameters such as Zener impedance and leakage current match the original specifications. Cross-reference AEC-Q101 certification if automotive usage is required.
