Overview
The BA157-AP is a fast recovery rectifier diode manufactured by Micro Commercial Components (MCC). It features a single silicon element housed in a DO-41 plastic package. The device supports a maximum average forward rectified current of 1 A and offers a repetitive peak reverse voltage rating of 400 V. It is designed for high-efficiency applications with low forward voltage characteristics.
Feature Summary
- Fast recovery switching capability for efficient power conversion
- Glass passivated junction for enhanced environmental stability
- Low leakage current to minimize power loss
- High surge current capability for robust operation
Applications
- General-purpose rectification in AC/DC converters
- Free-wheeling diodes in inductive load circuits
- Polarity protection in DC power supplies
Procurement Notes
Verify the specific suffix against official MCC documentation to confirm compliance status and marking details. Ensure the DO-41 package dimensions match the target PCB footprint. Confirm that the 400V reverse voltage rating meets the circuit's peak inverse voltage requirements before finalizing procurement.
Selection Notes
Select this component when a 1 A current rating and 400 V blocking voltage are required in a standard axial leaded package. Consider the fast recovery特性 if the application involves high-frequency switching or requires reduced reverse recovery time compared to standard rectifiers. Verify thermal management needs for the DO-41 form factor.
Part Context
This part belongs to the BA series of fast recovery rectifiers from Micro Commercial Components. It shares the DO-41 mechanical outline with other variants in the family, such as the BA158 and BA159, which differ primarily in their reverse voltage ratings. The -AP suffix typically denotes RoHS compliance and halogen-free manufacturing processes.
Replacement Considerations
Cross-reference with BA157 equivalents from other manufacturers like Taiwan Semiconductor or Semikron. Ensure substitute parts maintain the 1 A forward current and 400 V reverse voltage specifications while matching the DO-41 package for direct pin-to-pin replacement.
