1N4762AHB0G

Overview

The 1N4762AHB0G is a unidirectional voltage regulator diode manufactured by Taiwan Semiconductor Corporation. It features an 82 V nominal Zener voltage with a ±5% tolerance and a maximum power dissipation of 1 W. The device utilizes silicon technology and is housed in a DO-204AL (DO-41) axial through-hole package. It operates within a junction temperature range of -55 °C to 150 °C and exhibits a maximum dynamic impedance of 200 Ω. The component is AEC-Q101 qualified for automotive applications and complies with RoHS3 standards.

Feature Summary

• AEC-Q101 qualified for automotive reliability requirements
• Glass passivated junction construction for stability
• Axial leaded DO-204AL package design

Applications

• Automotive voltage regulation circuits
• General purpose voltage reference applications
• Overvoltage protection stages

Procurement Notes

Verify the specific suffix HB0G against official datasheets to confirm AEC-Q101 qualification status, as standard JEDEC variants may lack this certification. Ensure the procurement channel provides traceability documentation for automotive grade components. Confirm RoHS3 compliance status matches current regulatory requirements before finalizing orders.

Selection Notes

Select this component when a stable 82 V reference is required in high-reliability environments. The DO-41 package suits manual assembly or automated insertion processes. Consider the 1 W power rating and thermal resistance for heat dissipation needs. Verify that the ±5% tolerance meets circuit precision requirements compared to tighter tolerance alternatives.

Part Context

This part belongs to the 1N4762 series of 1 Watt Zener diodes produced by Taiwan Semiconductor. The series covers a wide voltage range from 3.3 V to 100 V. The HB0G suffix indicates specific packaging and qualification attributes distinct from standard commercial grades. It shares the same electrical baseline as other 1N4762 variants but differs in manufacturing specifications.

Replacement Considerations

Direct substitutes include 1N4762A from various manufacturers such as Microchip Technology or Central Semiconductor. Verify package compatibility and tolerance levels when swapping brands. Ensure replacement parts meet the same AEC-Q101 requirements if used in automotive contexts.
