Overview
The BA157GH is a fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a 400V repetitive peak reverse voltage and a 1A average forward rectified current rating. The device utilizes a DO-204AL (DO-41) axial through-hole package. Key electrical characteristics include a maximum forward voltage of 1.1V at 1A and a typical reverse recovery time of 150ns. The component is designed for general-purpose rectification applications requiring fast switching capabilities.
Feature Summary
- Fast recovery performance with a typical reverse recovery time of 150ns
- Halogen-free construction with green molding compound
- UL flammability classification rating of 94V-0
Applications
- General-purpose rectification in power supplies
- Freewheeling diodes in inductive load circuits
- DC-DC converter output rectification
Procurement Notes
Verify the specific suffix 'G' confirms the halogen-free green compound variant. Ensure the DO-204AL package matches the PCB footprint requirements. Confirm the 400V rating aligns with the circuit's peak inverse voltage demands. Check datasheet specifications for thermal resistance values to validate heat dissipation needs in the final assembly design.
Selection Notes
Select this component when a fast recovery diode is required for low-current applications up to 1A. The 400V rating suits medium-voltage DC circuits. The axial leaded package facilitates manual insertion or standard through-hole automated assembly processes. Consider the 150ns recovery time for switching frequencies where standard rectifiers may exhibit excessive losses.
Part Context
Taiwan Semiconductor Corporation produces discrete power rectifiers, including Schottky diodes and MOSFETs. The company operates manufacturing facilities compliant with automotive standards such as IATF16949. The BA157GH belongs to their fast recovery rectifier lineup, supporting industrial and consumer electronics markets with reliable semiconductor solutions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with generic equivalents based on matching electrical parameters: 400V VRRM, 1A IF, and <150ns trr in the DO-204AL package.
