Single Zener Diodes datasheet and documents for 1N4372

1N4372

Single Zener Diodes Overview

The Microchip Technology 1N4372 is a silicon unidirectional Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 3V with a tolerance of 10% and a maximum power dissipation of 0.5W. The device is housed in a hermetically sealed DO-35 axial leaded package, suitable for through-hole mounting. It operates within a temperature range of -65°C to +175°C and is classified as a single configuration diode.

Single Zener Diodes Feature Summary

Hermetically sealed glass axial package for environmental protection
High thermal stability supporting extended operating temperatures up to 175°C
Standard 10% voltage tolerance for general regulation tasks

Single Zener Diodes Applications

Precision voltage reference circuits
Overvoltage protection stages
General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as MACOM also produces this part number. Confirm RoHS compliance status, as historical data indicates non-compliance for certain variants. Ensure the package matches the required DO-35 form factor and that the 10% tolerance aligns with circuit design requirements before procurement.

Single Zener Diodes Selection Notes

Select this component when a robust, hermetically sealed Zener diode is required for high-reliability environments. The 0.5W power rating and wide temperature range make it suitable for demanding industrial or military applications where standard plastic packages may fail. Verify compatibility with existing PCB footprints for the DO-35 package.

Single Zener Diodes Part Context

This component belongs to the broader family of 0.5W Zener voltage regulators. It shares functional similarities with other parts in the series but is distinguished by its specific 3V nominal voltage and hermetic sealing. It serves as a fundamental discrete semiconductor element for stable voltage control in analog circuits.
