1N4762AP/TR8

Overview

The Microsemi Corporation 1N4762AP/TR8 is a single silicon Zener diode designed for through-hole mounting in the DO-204AL (DO-41) axial leaded package. It features a nominal Zener voltage of 82V with a tolerance of ±5% and a maximum power dissipation of 1W. The device operates within a temperature range of -65°C to +175°C, ensuring reliability in demanding environments. Packaged in reels, this component utilizes a glass passivated junction to provide stable voltage regulation characteristics suitable for various electronic circuit applications.

Feature Summary

• Glass passivated junction construction for enhanced stability
• High thermal performance supporting extended operating temperatures
• Axial leaded package design for reliable through-hole integration

Applications

• Voltage reference circuits requiring stable 82V regulation
• Overvoltage protection stages in industrial electronics
• Clamping applications in high-reliability communication systems

Procurement Notes

Verify the specific suffix AP/TR8 against official Microsemi documentation to confirm the exact tolerance and reel packaging configuration. Ensure compatibility with existing assembly processes regarding the DO-204AL form factor. Cross-reference datasheets for thermal derating curves to validate performance under actual load conditions before finalizing procurement specifications.

Selection Notes

Select this component when an 82V Zener voltage with tight ±5% tolerance is required in a standard axial package. Consider the 1W power rating and wide temperature range for robust designs. Compare against other 1N4762 variants if different tolerances or non-lead-free compliance are acceptable for the target application environment.

Part Context

This part belongs to the standard 1N47xx series of Zener diodes manufactured by Microsemi. These components are widely recognized for their consistent electrical characteristics and durability. The 1N4762 designation specifically identifies the 82V breakdown voltage variant within this extensive family of discrete semiconductor devices used globally in power management and signal conditioning.

Replacement Considerations

Equivalent parts include the MSP1N4762G and SMBG4762AP from Microsemi, offering similar electrical ratings but potentially different package styles such as hermetic sealed glass or plastic SMBG configurations. Verify pinout compatibility and thermal requirements when substituting.
