Overview
The A187M is a general-purpose rectifier diode manufactured by Powerex Inc. It features a maximum repetitive peak reverse voltage of 200 V and a maximum average forward output current of 150 A. The device utilizes silicon as the semiconductor material and is housed in a DO-205AA package with a post/stud mount form factor. Key electrical characteristics include a maximum reverse recovery time of 2 µs, making it suitable for fast recovery power applications.
Feature Summary
- Designed for fast recovery power applications
- Utilizes silicon semiconductor material
- Features stud mount configuration for robust thermal management
Applications
- Fast recovery power circuits
- General purpose rectification
- Industrial power conversion systems
Procurement Notes
Verify the specific suffix 'M' against official Powerex documentation to confirm exact mechanical or electrical variations compared to standard variants like A187RB. Ensure compatibility with existing heatsinking infrastructure due to the stud mount package style. Confirm RoHS compliance status if required by project specifications, as older industrial components may vary in regulatory adherence.
Selection Notes
Select this component when a high-current, low-voltage rectifier with fast recovery characteristics is required. The 150 A rating supports substantial load currents, while the 200 V breakdown voltage limits its use to lower voltage AC-DC conversion stages. Consider the physical mounting requirements associated with the DO-205AA stud mount package during PCB or chassis design.
Part Context
This component belongs to the Powerex A-series of general-purpose rectifier diodes. These devices are engineered for industrial and commercial power electronics where reliability under high current conditions is critical. The series typically offers various voltage and current ratings to accommodate different circuit topologies within the same packaging family.
Replacement Considerations
Officially documented similar part numbers include A187PB, A187PD, A187PE, A187P, A187RPE, A187RPD, A187RPB, A187RM, and A187B. Verify pinout and parameter equivalence before substitution.
