Diode Arrays Procurement Notes

Verify the specific suffix 'PT' corresponds to the TO-247AD package variant when sourcing. Confirm compliance with RoHS Directive 2011/65/EU and WEEE 2002/96/EC requirements if environmental regulations apply. Ensure the supplier provides documentation confirming UL File # E-326243 recognition. Cross-reference the manufacturer's official datasheet to validate the 500V rating against other variants in the HER300x series.

Diode Arrays Selection Notes

Select this component for applications requiring high efficiency and fast recovery characteristics at 30A. The TO-247AD package offers superior thermal performance compared to smaller packages. Compare the 500V rating against system voltage spikes to ensure adequate margin. Consider the low forward voltage for reducing power loss in high-current paths. Evaluate thermal management solutions based on the specified junction temperature limits.

Diode Arrays Part Context

This part belongs to the HER300x series of glass-passivated high-efficiency rectifiers from Taiwan Semiconductor. The series covers voltage ratings from 50V to 600V while maintaining a consistent 30A current capability. These devices are designed to replace standard rectifiers in applications where speed and efficiency are critical. The common cathode configuration allows for easy integration into bridge or half-bridge topologies.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include HER3001PT through HER3007PT, differentiated primarily by their reverse voltage ratings. Verify that alternative parts match the 30A current and TO-247AD package constraints. Check equivalent manufacturers for parts with identical electrical specifications and pinout compatibility.
