1N4762A-TAP

Overview

The 1N4762A-TAP is a unidirectional silicon Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features an 82 V nominal breakdown voltage with a maximum power dissipation of 1.3 W. The component utilizes the DO-204AL (DO-41) axial through-hole package and exhibits a maximum dynamic impedance of 200 Ω. It operates within a temperature range of -55 °C to +175 °C junction temperature and complies with RoHS standards.

Feature Summary

• Provides stable voltage regulation at a fixed 82 V breakdown threshold
• Engineered for high thermal stability with a 175 °C maximum junction rating
• Constructed in a robust glass-encapsulated DO-41 axial package

Applications

• Voltage reference circuits requiring precise 82 V stabilization
• Overvoltage protection stages in power supply inputs
• Clamping applications in signal conditioning networks

Procurement Notes

Verify current availability status as this specific part number may be obsolete or discontinued by the manufacturer. Confirm that any substitute components maintain identical electrical specifications, particularly the 82 V Zener voltage and 1.3 W power rating, to ensure circuit compatibility without redesign.

Selection Notes

Select this component when a standard 82 V Zener reference is required in an axial leaded format. Ensure the application environment supports the specified operating temperature range and that the 200 Ω dynamic impedance meets the noise and regulation requirements of the design.

Part Context

This device belongs to the 1N47xx series of general-purpose Zener diodes widely used in industrial and consumer electronics. The TAP suffix typically denotes tape-and-reel packaging for automated assembly processes, distinguishing it from bulk or other packaging variants within the same electrical specification family.

Replacement Considerations

Public records indicate the 1N4762AGE3 by Microchip Technology as a similar alternative. Verify pinout compatibility and exact parameter matching before substitution.
