HER3004PTH

Diode Arrays Overview

The HER3004PTH is a glass-passivated high-efficiency rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a single silicon junction in a TO-247AD (TO-3P) package, rated for a maximum repetitive peak reverse voltage of 400V and an average forward rectified current of 30A. The device exhibits a maximum non-repetitive peak forward surge current of 300A and a low thermal resistance structure. Electrical characteristics include a maximum forward voltage drop of 1.5V at rated current and a maximum reverse recovery time of 0.05µs. It operates within a junction temperature range up to 150°C.

Diode Arrays Feature Summary

• Glass passivation provides mechanical strength and protection against external physical stress
• Low forward voltage drop minimizes conduction losses for improved system efficiency
• Superfast recovery time reduces switching losses during high-frequency operation
• Low thermal resistance facilitates effective heat dissipation in power applications

Diode Arrays Applications

• High-efficiency DC/DC converters
• Free-wheeling rectification in PWM circuits
• Power factor correction circuits

Diode Arrays Procurement Notes

Verify the specific suffix 'PTH' against the manufacturer's official datasheet to confirm the exact pinout configuration and mechanical dimensions associated with the TO-247AD package variant. Ensure that the ordering information explicitly references the HER3004PTH part number to distinguish it from other HER300x series packages. Cross-reference the RoHS compliance status and UL recognition file numbers provided in the official documentation prior to procurement.

Diode Arrays Selection Notes

Select this component for applications requiring high current handling capabilities combined with fast switching speeds. The TO-247AD package is suitable for through-hole mounting where robust mechanical stability and efficient thermal management are required. Compare the 400V reverse voltage rating and 30A current capacity against circuit requirements to ensure adequate derating margins under maximum operating temperatures.

Diode Arrays Part Context

This component belongs to the HER300x series of high-efficiency rectifiers designed for general-purpose power conversion. The series offers various voltage ratings ranging from 50V to 600V while maintaining consistent current and recovery time specifications. The PTH designation indicates a specific leaded package format intended for high-power density designs requiring reliable performance in demanding electrical environments.

Diode Arrays Replacement Considerations

Compatible substitutes include the HER3004PT from Taiwan Semiconductor and equivalent parts from other manufacturers such as Micro Commercial Components or Panjit, provided they share the same 30A current rating, 400V voltage rating, and TO-247AD package type.
