The BYG20J is a high-efficiency surface mount rectifier manufactured by Taiwan Semiconductor. It features a glass passivated junction chip and is housed in a DO-214AC (SMA) package. The device supports a maximum average forward rectified current of 1.5A with repetitive peak reverse voltages ranging from 200V to 600V depending on the specific suffix variant. It offers fast switching capabilities for high efficiency and high surge current capability, making it suitable for automated placement.
Verify the specific voltage rating suffix (e.g., D for 200V, G for 400V, J for 600V) as the base part number covers multiple variants. Confirm RoHS compliance and halogen-free status via the manufacturer's datasheet. Check AEC-Q101 qualification requirements if automotive applications are intended, noting that only specific suffixes like H may qualify.
Select based on required reverse voltage and forward current ratings within the 1.5A SMA package constraints. Ensure compatibility with automated assembly processes due to the reel packaging format. Verify thermal resistance parameters against system heat dissipation requirements. Consider the operating temperature range and moisture sensitivity level for environmental robustness.
This component belongs to the BYG series of high-efficient surface mount rectifiers from Taiwan Semiconductor. The series utilizes a DO-214AC (SMA) case style, providing a compact solution for modern electronics. The product line emphasizes reliability through glass passivation and compliance with international environmental directives.
Direct substitutes include other SMA-packaged 1.5A fast recovery rectifiers with matching voltage ratings. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference specific suffix codes for exact electrical parameter alignment.
