123NQ080-1

Overview

The 123NQ080-1 is a power surface mount Schottky rectifier manufactured by SMC Diode Solutions. It features an 80V DC reverse voltage rating and supports a continuous forward current of 120A. The device utilizes Half-Pak module packaging, designated as PRM1-1, which provides a lower profile compared to traditional DO-5 packages. It is designed for chassis mounting and operates at junction temperatures up to 175°C.

Feature Summary

• Schottky barrier technology for low voltage drop and fast switching
• Half-Pak module construction replacing three parallel DO-5 diodes
• Chassis mount configuration for high-power applications

Applications

• High-current DC-DC converters
• Power supply freewheeling circuits
• Industrial motor drive rectification

Procurement Notes

Verify the specific suffix -1 against the manufacturer's latest datasheet to confirm mechanical dimensions and pinout compatibility. Ensure thermal management solutions support the 175°C junction temperature rating. Confirm that the chassis mount style matches the intended PCB or heatsink interface requirements before finalizing orders.

Selection Notes

Select this component when high current capacity and low forward voltage are required in a compact form factor. The Half-Pak design simplifies assembly by eliminating the need for multiple parallel discrete diodes. Consider thermal resistance characteristics and available mounting space when integrating into high-power systems requiring robust rectification capabilities.

Part Context

This part belongs to the 123NQ series of power Schottky rectifiers from SMC Diode Solutions. The series offers various voltage ratings while maintaining consistent current handling through standardized module packaging. The -1 suffix typically denotes specific packaging or revision details within the product line.

Replacement Considerations
