1N1190AR

Single Diodes Overview

The Microchip Technology 1N1190AR is a standard recovery rectifier diode designed for high-power applications. It features a maximum DC reverse voltage (Vr) of 600 V and an average forward current (Io) rating of 35 A. The device utilizes a DO-203AB (DO-5) package with stud mount installation. Electrical characteristics include a maximum forward voltage (Vf) of 1.4 V at 110 A and a reverse leakage current of 10 µA at 600 V. The junction temperature range spans from -65°C to 175°C, ensuring reliability in demanding environments.

Single Diodes Feature Summary

• High current handling capability with a 35 A average forward rectified current rating
• Robust voltage blocking performance supporting up to 600 V DC reverse voltage
• Durable construction suitable for stud mounting in industrial power systems
• Wide operating junction temperature range extending to 175°C

Single Diodes Applications

• Industrial power supply rectification circuits
• Motor drive and control system power stages
• General-purpose high-current rectification tasks

Single Diodes Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure the component meets MIL-PRF-19500/297 requirements if military grade certification is necessary for the application. Confirm RoHS non-compliance status aligns with project environmental regulations before procurement.

Single Diodes Selection Notes

Select this component when a 600 V reverse voltage rating and 35 A continuous current capacity are required. The DO-203AB package necessitates stud mount thermal management solutions. Consider the standard recovery speed (>500 ns) suitability for low-frequency AC-to-DC conversion rather than high-speed switching applications.

Single Diodes Part Context

This part belongs to the 1N1190 series of silicon rectifier diodes manufactured by Microchip Technology. It shares electrical specifications with other variants in the series but differs in packaging or qualification levels. The DO-203AB form factor is standard for high-power discrete diodes requiring direct heatsink attachment.

Single Diodes Replacement Considerations

Consult the official datasheet for cross-reference information. Verify that any substitute maintains the 600 V Vr, 35 A Io, and DO-203AB package compatibility.
