PR1503S-A

Single Diodes Overview

The PR1503S-A is a fast recovery rectifier from Diodes Incorporated, featuring a diffused junction and DO-41 package. It supports a peak repetitive reverse voltage of 200 V and an average rectified output current of 1.5 A at 50°C. The device exhibits a forward voltage of 1.2 V at 1.5 A and a reverse recovery time ranging from 150 to 250 ns. It withstands a non-repetitive peak forward surge current of 50 A and operates within a temperature range of -65°C to +150°C.

Single Diodes Feature Summary

• Fast switching capability for high efficiency applications
• High current capability with low forward voltage drop
• Surge overload rating up to 50A peak
• Low reverse leakage current

Single Diodes Applications

• Single phase half-wave rectification
• Resistive or inductive load circuits
• General purpose power supply designs

Single Diodes Procurement Notes

Verify the component status as not recommended for new design before procurement. Confirm the DO-41 package type matches the 'S' suffix requirement. Ensure compatibility with existing PCB footprints and thermal management strategies. Check for RoHS compliance documentation if required by specific project standards.

Single Diodes Selection Notes

Select this component for applications requiring fast recovery characteristics and moderate voltage blocking capabilities. Consider the 1.5 A current rating and derating curves for ambient temperatures above 50°C. Evaluate the 200 V reverse voltage margin against circuit peaks. Assess thermal resistance requirements for reliable operation under continuous load conditions.

Single Diodes Part Context

This part belongs to the PR1501/S through PR1505/S series of fast recovery rectifiers. The series offers varying reverse voltage ratings from 50 V to 600 V while maintaining consistent current handling and package options. The PR1503S-A specifically targets the 200 V rating tier within this lineup.

Single Diodes FAQ

What does the 'S' suffix indicate in the PR1503S-A model?

The 'S' suffix designates that the component is housed in a DO-41 plastic package.

How should the current be derated for capacitive loads?

For capacitive loads, the current should be derated by 20% compared to resistive or inductive loads.
