BA158G-K

Overview

The BA158G-K is a fast recovery plastic rectifier manufactured by Taiwan Semiconductor Corporation. It features a single silicon element with a maximum average forward rectified current of 1A and a maximum repetitive peak reverse voltage of 600V. The device utilizes a DO-204AL (DO-41) axial leaded package, providing an isolated case connection. It operates within a junction temperature range of -65°C to +175°C. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 30A at 8.3ms single half-sine-wave, a maximum DC forward voltage of 1.3V at 1A, and a maximum reverse leakage current of 5µA at 600V.

Feature Summary

• Fast recovery performance suitable for high-frequency switching applications
• High thermal stability with extended junction temperature rating up to 175°C
• Plastic encapsulation designed for mechanical robustness and environmental protection

Applications

• High frequency rectification in power supply circuits
• Free wheeling diode configurations in inductive load driving
• General purpose rectification in consumer electronics

Procurement Notes

Verify the specific suffix K against official datasheets to confirm packaging or tolerance variations. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the manufacturer's latest documentation for any updates on pinout or absolute maximum ratings before finalizing procurement specifications.

Selection Notes

Select this component when a 600V reverse voltage rating and 1A continuous current capacity are required. The fast recovery characteristic makes it appropriate for applications where standard rectifiers may exhibit excessive reverse recovery charge. Consider the DO-41 package size for through-hole mounting constraints and verify thermal management needs based on ambient operating conditions.

Part Context

This part belongs to the BA158 series of fast recovery rectifiers from Taiwan Semiconductor. It serves as a semiconductor solution for converting alternating current to direct current in low to medium power electronic systems. The device is engineered to replace older silicon rectifiers in modern designs requiring improved switching speeds and higher thermal endurance.

Replacement Considerations

Compatible substitutes include the Vishay BA158-E3/54 and generic equivalents such as the FR107 or UF4007 series, provided they meet the 600V reverse voltage and 1A current specifications. Verify that replacement parts maintain the same DO-204AL package dimensions and fast recovery time characteristics to ensure circuit compatibility.
