1N5074

Single Zener Diodes Overview

The 1N5074 is a high-reliability Zener diode manufactured by Microchip Technology, designed for voltage regulation and protection applications. It features a nominal Zener voltage of 22 V with a tolerance of ±5%. The device has a maximum power dissipation of 3 W and operates within an extended temperature range from -65°C to 175°C. Packaged in a through-hole axial leaded configuration (DO-15), it utilizes glass passivation for durability. Key electrical characteristics include a reverse leakage current of 500 nA at 16.7 V and a forward voltage of 1.2 V at 200 mA.

Single Zener Diodes Procurement Notes

Verify the specific manufacturer lot and date code upon receipt to ensure compliance with project reliability requirements. Confirm that the component matches the specified DO-15 axial package dimensions. Check for any handling precautions related to the glass passivation layer during soldering processes to maintain device integrity.

Single Zener Diodes Selection Notes

Select this component when a robust 22 V Zener reference is required in high-temperature environments. The 3 W power rating supports moderate current loads in axial packages. Ensure the application does not exceed the 175°C junction temperature limit. Consider derating guidelines for continuous operation near maximum thermal limits.

Single Zener Diodes Part Context

This part belongs to the standard Zener diode family offered by Microchip Technology. It serves as a discrete semiconductor solution for analog circuit design. The axial leaded format facilitates easy integration into through-hole printed circuit boards. It is distinct from surface-mount variants or transient voltage suppressors.
