HER201GH

Single Diodes Overview

The HER201GH is a high-efficiency rectifier diode from Taiwan Semiconductor, rated for a maximum repetitive peak reverse voltage of 50V and a continuous forward current of 2A. It utilizes a glass passivated chip junction within a DO-204AC (DO-15) axial leaded package. The device features a typical forward voltage drop of 1.0V at 2A and a peak non-repetitive surge current capability of 60A. Electrical characteristics include a maximum reverse leakage current of 5µA at 25°C and a typical reverse recovery time of 50ns. The component operates across a junction temperature range of -55°C to +150°C.

Single Diodes Procurement Notes

Verify the specific suffix configuration when ordering. The 'H' suffix indicates AEC-Q101 automotive qualification, while the 'G' suffix denotes standard RoHS compliance. Confirm whether tape-and-reel or ammo box packaging is required based on production needs. Ensure the part number explicitly includes both suffixes to match the intended qualification and environmental standards.

Single Diodes Selection Notes

Select this component for applications requiring robust high-efficiency rectification in through-hole designs. The 2A rating and 50V blocking voltage suit low-voltage power conversion stages. Verify that the thermal resistance and operating temperature limits align with the system's heat dissipation capabilities. Consider the AEC-Q101 qualification if automotive reliability standards are mandatory for the end-use environment.

Single Diodes Part Context

This part belongs to the HER20xG series, which covers voltage ratings from 50V to 1000V. All members share identical mechanical dimensions and electrical parameters except for the reverse voltage rating. The HER201G specifically provides the lowest voltage option in the lineup, maintaining the same 2A current handling and fast recovery characteristics as higher-rated siblings.

Single Diodes Replacement Considerations

Direct substitutes within the same family include HER202GH, HER203GH, and others up to HER208GH. These parts share identical physical packages and current ratings but offer higher reverse voltage capabilities. Ensure the replacement voltage rating meets or exceeds the circuit requirements without exceeding the original design constraints.
