Overview
The BA157-TP is a fast recovery rectifier diode manufactured by Micro Commercial Components (MCC). It features a single-element silicon construction housed in the DO-41 axial leaded package. The device provides a continuous forward current of 1 A and supports reverse voltage ratings ranging from 400 V to 1000 V, with the specific BA157 variant rated at 400 V. Key electrical characteristics include low leakage current and high surge current capability, designed for efficient performance in general-purpose rectification applications.
Feature Summary
- Fast recovery switching characteristics suitable for high-frequency circuits
- Low leakage current operation for improved efficiency
- High surge current capability for robust transient handling
- Epoxy casing meets UL 94 V-0 flammability rating standards
Applications
- General-purpose rectification in power supplies
- Inverter and converter circuits
- DC-DC converter stages
- Battery charging systems
Procurement Notes
Verify the exact reverse voltage rating required for your circuit design, as the BA15x series spans multiple voltage classes. Confirm that the DO-41 package dimensions align with your PCB footprint constraints. Ensure compliance with RoHS directives if halogen-free variants are not explicitly specified in the final order documentation.
Selection Notes
Select this component when a 1 A current rating and fast recovery speed are necessary for rectification tasks. Compare the specific peak repetitive reverse voltage requirements against the available series options to ensure adequate safety margins. Consider the thermal management capabilities of the DO-41 package for your expected operating temperature range.
Part Context
This part belongs to the BA157GP through BA159GP family of fast recovery rectifiers from MCC. These components share common packaging and basic structural features but differ primarily in their maximum reverse voltage ratings. The series is engineered for reliability in compact electronic designs requiring efficient AC-to-DC conversion.
Replacement Considerations
Compatible substitutes include FR3A, RGP30K, and BY296. Verify that alternative parts match the 1 A forward current and 400 V reverse voltage specifications. Ensure the replacement maintains the DO-41 package style and fast recovery characteristics for direct integration.
