1N4923A/TR

Single Zener Diodes Overview

The Microchip Technology 1N4923A/TR is a single silicon Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 19.2 V with a maximum power dissipation of 500 mW. The component is housed in an axial DO-204AH (DO-35) glass passivated package, suitable for through-hole mounting. This specific variant includes the /TR suffix, indicating it is supplied in a tape and reel format for automated assembly processes.

Single Zener Diodes Feature Summary

• Utilizes glass passivation for environmental protection
• Designed for stable voltage regulation at 19.2 V
• Available in axial leaded package for through-hole integration

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection stages
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify that the /TR suffix corresponds to the required tape and reel packaging configuration for your manufacturing line. Confirm the DO-204AH package dimensions match your PCB footprint requirements. Ensure the 19.2 V Zener voltage specification aligns with the target circuit design parameters before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 19.2 V regulation point is required within a 500 mW power budget. The axial DO-35 package is appropriate for standard through-hole assembly techniques. Consider the tape and reel delivery format if high-volume automated placement is necessary for production efficiency.

Single Zener Diodes Part Context
