1N1187R is listed in the Single Diodes range at ChipApex. The manufacturer field lists Microchip Technology. Its product description is DIODE STD REV 300V 40A DO203AB. Review the specifications below when checking this part for your BOM.
The Microchip Technology 1N1187R is a standard recovery rectifier diode housed in a DO-203AB-2 package. It features a maximum average forward current of 35 A and a peak repetitive reverse voltage of 300 V. The device offers an 800 A surge rating and utilizes glass passivated die construction with glass-to-metal sealing.
Verify the specific datasheet version from Microchip Technology or authorized distributors to confirm exact electrical limits and mechanical dimensions. Ensure the DO-203AB-2 package matches the target PCB footprint. Check for RoHS compliance status as some variants may be non-RoHS.
Select this component when a robust silicon power rectifier with high surge tolerance is required. The 300 V reverse voltage rating suits medium-voltage applications. Compare thermal resistance values against system heat dissipation requirements to ensure adequate cooling solutions are implemented.
This part belongs to the 1N1187 series of silicon power rectifiers manufactured by Microchip Technology. It is functionally similar to other industry-standard rectifiers but specified under Microchip's quality and manufacturing guidelines. The series typically includes variants with different voltage ratings.
Compatible substitutes include Vishay PCS 1N1187R and GeneSiC Semiconductor 1N1187R, provided they meet the 35 A forward current and 300 V reverse voltage specifications in a compatible DO-5 or DO-203AB package.
