HER101G R0G

Single Diodes Overview

The HER101G R0G is a silicon rectifier diode from the HER101G–HER108G series by Taiwan Semiconductor. It features a single die configuration in a DO-204AL (DO-41) package. Key electrical parameters include a forward current of 1 A, a repetitive peak reverse voltage of 50 V, and a surge peak forward current of 30 A. The device operates within a junction temperature range of -55 to +150 °C. Electrical specifications specify a maximum forward voltage of 1.0 V at 1 A, a typical reverse current of 5 µA at rated voltage and 25 °C, and a reverse recovery time of 50 ns.

Single Diodes Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to confirm packaging type and quantity. The datasheet lists standard tape and reel or ammo box options. Confirm that the suffix corresponds to the required packing format. Ensure compliance with RoHS and halogen-free requirements if specified for the project. Cross-reference the date code prefix and marking diagram for traceability.

Single Diodes Selection Notes

Select this component for general-purpose rectification requiring high efficiency and reliability. The 50 V rating defines the voltage limit for the HER101G variant within the series. Consider the thermal resistance values for heat dissipation planning. The DO-204AL package suits through-hole mounting. Evaluate the reverse recovery time for high-frequency switching constraints. Ensure the application does not exceed the 30 A surge current limit.

Single Diodes Part Context

This part belongs to the HER101G–HER108G series of high-efficiency rectifiers manufactured by Taiwan Semiconductor. The series covers voltage ratings from 50 V to 1000 V. The 'G' suffix indicates green compound material. The 'H' suffix denotes AEC-Q101 qualification, which is not present in the base HER101G model. These diodes are designed for robust performance in power conversion environments.

Single Diodes Replacement Considerations

Direct substitutes must match the 1 A current, 50 V reverse voltage, and DO-204AL package. Verify equivalent forward voltage and reverse recovery characteristics. Check for identical mechanical dimensions and lead plating specifications. Ensure the replacement meets the same thermal and environmental standards.
