Diode Arrays Procurement Notes

Verify the specific suffix 'H' against official Taiwan Semiconductor documentation to confirm mechanical or material variations. Ensure the procurement source provides valid datasheets matching the SF804GH part number. Confirm RoHS compliance status and lead-free terminal plating specifications directly from the manufacturer's release notes before ordering.

Diode Arrays Selection Notes

Select this component for designs requiring an 8A rectifier with a 400V blocking voltage in a TO-220AC housing. Consider the 1.3V forward voltage drop for thermal management calculations. Verify that the isolated cathode-to-case connection meets the circuit's grounding requirements. Ensure the operating environment stays within the specified -65°C to 150°C temperature range.

Diode Arrays Part Context

This part belongs to the SFA series of glass passivated super fast rectifiers from Taiwan Semiconductor. These components are designed for general purpose rectification in low voltage, high frequency applications. The series emphasizes high reliability and low power loss, utilizing a molded plastic case with UL 94V-0 flame retardant epoxy.

Diode Arrays Replacement Considerations

Direct substitutes may include other 8A, 400V TO-220AC rectifiers from the same family, such as the SF804G. Verify pinout compatibility and thermal resistance values when considering alternatives from different manufacturers.
