1N1189A

Single Diodes Overview

The 1N1189A is a silicon rectifier diode manufactured by Microchip Technology. It features a maximum repetitive peak reverse voltage of 500 V and an average forward rectified current rating of 40 A. The component utilizes the DO-203AB (DO-5) axial leaded package with stud mount capability. It is designed for standard recovery applications, operating within a junction temperature range of -65°C to +200°C.

Single Diodes Feature Summary

• High current handling capability suitable for power conversion circuits
• Robust thermal performance with extended junction temperature limits
• Standard recovery characteristics for general-purpose rectification

Single Diodes Applications

• Industrial power supply rectification
• Battery charging systems
• DC power distribution units

Single Diodes Procurement Notes

Verify the specific manufacturer designation, as Digitron also produces this part number. Confirm RoHS compliance status, as sources indicate non-compliance. Ensure the DO-203AB package dimensions match the design requirements before procurement.

Single Diodes Selection Notes

Select this component for high-current DC applications requiring 500 V blocking voltage. Consider the DO-203AB package for through-hole or stud mounting configurations. Evaluate thermal management needs given the 40 A current rating and high junction temperature tolerance.

Single Diodes Part Context

This device belongs to the 1N118x series of high-power rectifiers. It shares the DO-203AB form factor with similar models like the 1N1188A and 1N1190A. The series is characterized by robust construction for industrial environments.

Single Diodes Replacement Considerations

The 1N1188A offers identical 40 A current but lower 400 V reverse voltage. The 1N1190A provides higher 600 V reverse voltage at 35 A current. Verify voltage derating requirements when substituting.
