Diode Arrays Procurement Notes

Verify the specific suffix codes on the ordering information to confirm package type and compliance status. Ensure the selected variant matches the required voltage rating for the target circuit application. Confirm that the manufacturer documentation aligns with the requested pinout and thermal specifications before finalizing procurement orders.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for high-current applications. The 16A rating suits medium-power conversion tasks. Verify that the 400V reverse voltage rating exceeds the peak inverse voltage expected in the circuit. Consider the TO-220AB package for through-hole mounting requirements and adequate thermal dissipation capabilities.

Diode Arrays Part Context

This part belongs to the HERF series of glass passivated high-efficiency rectifiers from Taiwan Semiconductor. The series offers various voltage ratings while maintaining consistent current handling capabilities. The HERF designation indicates a fast recovery characteristic suitable for high-frequency switching environments compared to standard rectifiers.

Diode Arrays Replacement Considerations

Cross-reference with other manufacturers offering 16A dual common cathode rectifiers in TO-220AB packages. Verify that substitute parts meet or exceed the 400V reverse voltage and 16A forward current specifications. Ensure thermal resistance and package dimensions are compatible with existing board layouts.
