HER1605G

Diode Arrays Overview

The HER1605G is a glass-passivated high-efficiency rectifier manufactured by Taiwan Semiconductor. It features a dual common cathode configuration housed in a TO-220AB-3 package for through-hole mounting. The device supports a maximum repetitive reverse voltage of 400 V and an average forward rectified current of 16 A. Key electrical parameters include a maximum forward voltage of 1 V, a peak non-repetitive surge current of 125 A, and a maximum reverse current of 10 uA. The component exhibits a fast recovery time of 50 ns and operates within a temperature range of -55 °C to +150 °C.

Diode Arrays Feature Summary

• Glass passivation provides mechanical strength and protection against moisture and chemical damage.
• Dual common cathode configuration enables efficient bridge rectification or push-pull circuit topologies.
• Fast recovery characteristics minimize switching losses and reduce electromagnetic interference during operation.

Diode Arrays Applications

• High-frequency AC/DC power supply circuits
• Motor drive freewheeling applications
• General-purpose rectification in industrial equipment

Diode Arrays Procurement Notes

Verify the specific suffix requirements with the manufacturer to ensure compliance with environmental directives such as RoHS and halogen-free standards. Confirm that the TO-220AB-3 package dimensions match your PCB footprint constraints. Request the official datasheet to validate thermal resistance values for your specific heatsinking strategy. Ensure the supplier provides traceability documentation for quality assurance purposes.

Diode Arrays Selection Notes

Select this component when a dual common cathode arrangement is required for 16 A loads at voltages up to 400 V. The 50 ns recovery time makes it suitable for frequencies higher than standard rectifiers but potentially lower than ultra-fast variants. Consider the TO-220AB-3 package for its robust thermal dissipation capabilities compared to smaller surface-mount options. Evaluate the 125 A surge rating against potential inrush currents in your specific application design.

Diode Arrays Part Context

This part belongs to the HER16 series of high-efficiency rectifiers from Taiwan Semiconductor. The series covers various voltage ratings from 50 V to 1000 V while maintaining consistent current handling and package styles. These devices are designed to replace older general-purpose rectifiers in applications demanding improved efficiency and faster switching performance.

Diode Arrays Replacement Considerations

Cross-reference with other manufacturers' 16 A, 400 V dual common cathode diodes in TO-220AB packages. Verify that substitute parts meet the same 50 ns recovery time and 1 V forward voltage specifications to maintain circuit performance equivalence.
