HER1606PT

Diode Arrays Overview

The HER1606PT is a glass-passivated high-efficiency rectifier manufactured by Taiwan Semiconductor Corporation. It features a dual common cathode configuration housed in a TO-247AD (TO-3P) package for through-hole mounting. The device supports a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current of 30 A per element. Key electrical parameters include a maximum non-repetitive peak forward surge current of 300 A, a typical forward voltage of 1.5 V, and a reverse leakage current of 10 µA at rated voltage. Operating temperatures range from -55 °C to +150 °C junction temperature.

Diode Arrays Feature Summary

• Glass passivation provides mechanical strength and protection against moisture and chemical corrosion.
• Dual common cathode design enables efficient bridge rectification or push-pull circuit topologies.
• Low thermal resistance structure facilitates effective heat dissipation in high-power applications.

Diode Arrays Applications

• High-frequency switching power supplies
• DC-DC converter output rectification
• Industrial motor drive freewheeling circuits

Diode Arrays Procurement Notes

Verify the specific suffix 'PT' with the manufacturer to confirm lead times and packaging details, as suffixes often denote tape-and-reel quantities distinct from tube packaging. Confirm RoHS compliance status and AEC-Q101 automotive qualification requirements directly with Taiwan Semiconductor prior to finalizing procurement orders.

Diode Arrays Selection Notes

Select this component when high current handling and fast recovery characteristics are required in a robust TO-247 package. Ensure the system's thermal management can maintain junction temperatures within the specified limits under continuous 30 A load conditions. Verify that the 600 V reverse voltage rating exceeds the peak inverse voltage present in the target circuit topology.

Diode Arrays Part Context

This part belongs to the HER series of high-efficiency rectifiers from Taiwan Semiconductor. The series utilizes glass passivation technology to enhance reliability and withstand harsh environmental conditions. The TO-247 package variant offers superior thermal performance compared to smaller packages, making it suitable for demanding industrial and commercial power conversion applications requiring high current capacity.

Diode Arrays Replacement Considerations

Direct substitutes may include other 30 A, 600 V dual common cathode rectifiers in TO-247 packages from manufacturers such as Vishay or ON Semiconductor. Verify pinout compatibility and thermal resistance specifications before substitution. Generic equivalents must match the 300 A surge current capability and 150 °C operating temperature range.
