1N4764AP/TR8

Overview

The Microchip Technology 1N4764AP/TR8 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 100 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and operates within a temperature range of -65 °C to +175 °C. It utilizes an axial DO-204AL (DO-41) package and is supplied in a reel format.

Feature Summary

• Provides stable voltage regulation across a wide operating temperature range
• Features hermetic-sealed glass encapsulation for environmental protection
• Designed for high-reliability through-hole mounting applications

Applications

• Voltage reference circuits requiring high stability
• Overvoltage protection in industrial systems
• Power supply regulation modules

Procurement Notes

Verify the specific suffix 'AP' indicates the required 5% tolerance and 'TR8' denotes the reel packaging configuration. Confirm that the DO-204AL package dimensions match the target PCB footprint. Ensure the manufacturer source is recognized as Microchip Technology or its authorized predecessor entities to guarantee component authenticity and traceability.

Selection Notes

Select this component when a 100 V regulation point with tight 5% tolerance is required. The 1 W power rating supports moderate current loads. The extended temperature range up to 175 °C makes it suitable for harsh environments where standard commercial grade parts may fail. The axial leaded package facilitates manual assembly or wave soldering processes.

Part Context

This part belongs to the 1N47xx series of 1 Watt Zener diodes manufactured by Microchip Technology. The series offers a broad selection of voltage values from 3.3 V to 100 V. The 'G' suffix typically denotes glass body construction, while 'P' indicates plastic. This specific variant combines the robust glass encapsulation with precise voltage tolerance specifications.

Replacement Considerations

Compatible substitutes include other 1N4764 variants with matching 100 V and 1 W ratings. Verify that alternative packages such as DO-41 are electrically equivalent. Check if tighter tolerances like 1% or 10% meet the circuit requirements. Ensure the replacement maintains the same hermetic sealing and temperature capabilities.
