1N4762A B0G

Overview

The 1N4762A B0G is a silicon unidirectional voltage regulator diode manufactured by Taiwan Semiconductor Corporation. It features an 82 V nominal Zener voltage with a 5% tolerance and a 1 W maximum power dissipation rating. The device utilizes a DO-204AL (DO-41) axial leaded package with plastic encapsulation. Electrical characteristics include a maximum dynamic impedance of 200 Ω and a typical reverse leakage current below 5 μA for voltages above 11 V. The component operates within a temperature range of -55 °C to +150 °C and complies with RoHS directives.

Feature Summary

• Glass passivated junction construction for enhanced stability
• Built-in strain relief in the DO-41 package design
• Low inductance structure suitable for switching applications

Applications

• Voltage regulation circuits requiring stable reference levels
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific B0G suffix against official Taiwan Semiconductor documentation to confirm packaging details and compliance status. Ensure the procurement channel provides valid traceability for the DO-41 plastic package variant. Cross-reference the manufacturer's latest datasheet to confirm availability and any potential obsolescence notices prior to finalizing orders.

Selection Notes

Select this component when a standard 82 V Zener diode with 1 W power handling is required in an axial through-hole configuration. The plastic encapsulation offers lower thermal resistance compared to glass-body options, while maintaining isolation. Consider the 200 Ω dynamic impedance specification for circuit designs where voltage stability under varying current loads is critical.

Part Context

This part belongs to the widely used 1N47xx series of 1 Watt Zener diodes. The 1N4762A designation specifically identifies the 82 V breakdown voltage variant within this family. Taiwan Semiconductor produces this component as a general-purpose discrete semiconductor device, adhering to JEDEC mechanical outline standards for the DO-41 package.

Replacement Considerations

Compatible substitutes include the MSP1N4762G from Microsemi, which shares the 82 V rating but differs in hermetic sealing and operating temperature limits. Other generic equivalents must match the 82 V Zener voltage, 1 W power dissipation, and DO-41 package form factor to ensure functional interchangeability.
