BYT28B-300HE3_A/I

Diode Arrays Overview

The BYT28B-300HE3_A/I is a dual common cathode ultrafast soft recovery rectifier manufactured by Vishay. It features a reverse voltage rating of 300V and a continuous forward current of 5A per element. The device utilizes a TO-263AB (D2PAK) surface-mount package. Key electrical parameters include a maximum repetitive peak reverse voltage of 300V, an average forward rectified current of 5A, and a maximum non-repetitive peak surge current of 100A. The component exhibits a fast reverse recovery time of 35ns and a low forward voltage drop of approximately 1.3V at 5A. It is designed for high-efficiency power conversion applications requiring rapid switching characteristics.

Diode Arrays Feature Summary

• Dual common cathode configuration for efficient bridge or half-bridge circuit implementation
• Ultrafast soft recovery characteristic minimizing switching losses and electromagnetic interference
• Surface-mount TO-263AB package optimized for automated assembly and thermal performance

Diode Arrays Applications

• High-frequency DC/DC converters
• Free-wheeling diodes in motor drives
• Power factor correction circuits

Diode Arrays Procurement Notes

Verify the specific suffix 'A/I' to ensure compatibility with the TO-263AB lead frame and tape-and-reel packaging format. Confirm that the 300V reverse voltage rating aligns with the system's peak inverse voltage requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the manufacturer source is authorized to guarantee authenticity and traceability of the semiconductor die.

Diode Arrays Selection Notes

Select this component when a dual common cathode topology is required for space-constrained designs. The 35ns reverse recovery time makes it suitable for frequencies exceeding standard recovery diodes. Compare the 1.3V forward voltage against system efficiency targets. Consider the thermal resistance of the TO-263AB package relative to the expected heat dissipation needs in the application environment.

Diode Arrays Part Context

This part belongs to the BYT28B series of ultrafast soft recovery rectifiers from Vishay. The series offers variants with different reverse voltage ratings, such as 400V options. The HE3 designation indicates a lead-free and halogen-free compliant product. The A/I suffix specifies the specific package type and reel quantity configuration distinct from other variants like the '/P' package.

Diode Arrays Replacement Considerations

Public confirmed substitutes include LQA20B300C. Verify pinout compatibility and thermal characteristics before substitution. Ensure the alternative device meets or exceeds the 35ns reverse recovery time and 300V blocking voltage requirements.
