1N4763AP/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N4763AP/TR8 is a single silicon Zener diode housed in a DO-204AL (DO-41) plastic axial leaded package. It features a nominal Zener voltage of 91V with a tolerance of 5% and a maximum power dissipation of 1W. The device operates within a temperature range from -65°C to +150°C. It is supplied in tape and reel packaging for automated assembly processes.

Single Zener Diodes Feature Summary

• Hermetically sealed glass body construction for enhanced environmental stability
• JEDEC registered part number ensuring standardized electrical characteristics
• Available in surface mount equivalents SMAJ4763A and MLL4763A

Single Zener Diodes Applications

• Voltage regulation in high-reliability electronic circuits
• Overvoltage protection for sensitive semiconductor components
• Reference voltage sources in precision measurement equipment

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration, as the 'TR8' indicates tape and reel packaging which differs from bulk units. Confirm RoHS compliance status, as standard versions may not meet current environmental directives. Cross-reference the manufacturer's latest datasheet to ensure the component matches the required voltage tolerance and thermal specifications for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a 91V Zener voltage is required in a through-hole DO-41 package. Consider the hermetic glass variant if higher temperature ratings or moisture resistance are necessary. Evaluate surface mount alternatives like the SMAJ series if board space constraints dictate a smaller footprint. Ensure the 1W power rating aligns with the circuit's expected power dissipation under all operating conditions.

Single Zener Diodes Part Context

This component belongs to the 1N4728A through 1N4764A series of 1-watt Zener diodes manufactured by Microsemi. The series offers an extensive voltage selection ranging from 3.3V to 100V. These devices are widely used in industrial and military applications due to their robust construction and availability in screened variants such as JAN, JANTX, and JANS.

Single Zener Diodes Replacement Considerations

Surface mount equivalents include SMAJ4763A and MLL4763A. For hermetic glass versions, consider the 1N4763AG series. Verify pinout compatibility and thermal performance before substituting with generic industry parts.
