1N4916A

Single Zener Diodes Overview

The Microchip Technology 1N4916A is a single Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 19.2 V with a tight tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW, making it suitable for low-power circuit protection and stabilization tasks. It utilizes a DO-35 (DO-204AH) axial through-hole package, ensuring reliable mounting on printed circuit boards. This component is classified as temperature compensated, providing stable performance across operating conditions.

Single Zener Diodes Feature Summary

• Temperature compensated design ensures stable voltage regulation under varying thermal conditions
• Tight voltage tolerance of ±5% maintains precision in reference and protection circuits
• Through-hole DO-35 package facilitates easy integration into standard PCB layouts

Single Zener Diodes Applications

• Voltage regulation in low-power electronic circuits
• Overvoltage protection for sensitive components
• Voltage reference sources in analog signal processing

Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., /TR) to confirm packaging type and compliance status such as RoHS. Confirm availability as this part may not be normally stocked by all distributors. Ensure the DO-35 package matches your board design requirements before ordering.

Single Zener Diodes Selection Notes

Select this component when a 19.2 V Zener voltage with high precision is required. The 500 mW power rating limits its use to low-current applications. Consider the through-hole package constraint if surface-mount solutions are preferred for automated assembly processes.

Single Zener Diodes Part Context

This part belongs to Microchip's series of single Zener diodes. It shares the DO-35 form factor with other variants in the family but differs in breakdown voltage and tolerance specifications. The 1N4916A is distinct from rectifier diodes despite similar numbering conventions in some legacy systems.

Single Zener Diodes Replacement Considerations

Check for direct substitutes with identical 19.2 V Zener voltage and ±5% tolerance. Verify that replacement parts support the same 500 mW power dissipation and DO-35 package dimensions to ensure mechanical compatibility.
