180NQ035-1

Overview

The SMC Diode Solutions 180NQ035-1 is a Schottky rectifier module featuring a single element configuration with a maximum repetitive peak reverse voltage of 35 V and an average rectified forward current rating of 180 A. The device utilizes a PRM1 (Half-Pak) non-isolated package designed for chassis mounting, offering a low profile compared to traditional parallel diode assemblies. It operates within a junction temperature range of -55°C to 175°C and incorporates guard ring technology to enhance ruggedness and long-term reliability under high-frequency switching conditions.

Feature Summary

• Utilizes unique Half-Pak module architecture to replace multiple parallel DO-5 packages, providing easier mounting and lower physical profile.
• Incorporates guard ring design for enhanced ruggedness and extended operational lifespan in demanding environments.
• Encapsulated using high-purity, high-temperature epoxy to ensure superior mechanical strength and moisture resistance.

Applications

• High-current switching power supplies
• Free-wheeling diode circuits
• Reverse battery protection systems

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer before finalizing procurement decisions. Confirm that the PRM1 package dimensions align precisely with the intended chassis mounting hardware and thermal interface requirements. Ensure that the selected component meets all necessary environmental certifications required for the target application market.

Selection Notes

Select this component when designing systems requiring high surge current capability and low forward voltage drop at elevated temperatures. The PRM1 package is suitable for applications where space constraints prevent the use of larger discrete modules. Evaluate thermal management strategies carefully, as the non-isolated nature of the package requires direct heat sinking through the base terminal.

Part Context

This part belongs to the 180NQ series of Schottky rectifiers from SMC Diode Solutions, specifically engineered for high-power density applications. The '1' suffix typically denotes the PRM1 (Half-Pak) packaging format, distinguishing it from other variants in the family such as those utilizing different casing styles or isolation levels.
