HER201G-T

Single Diodes Overview

The HER201G-T is a fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a glass passivated chip junction and is housed in a DO-204AC (DO-15) package. The device supports an average forward current of 2 A and offers a repetitive peak reverse voltage rating of 50 V. It withstands a surge peak forward current of 60 A under specified conditions. The maximum operating junction temperature reaches 150 °C, with a typical junction-to-ambient thermal resistance of 60 °C/W. Electrical characteristics include a maximum forward voltage of 1.0 V at rated current and a reverse recovery time of 50 ns.

Single Diodes Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm packaging type. The standard tape and reel option contains 3,500 units per reel, while the A0G variant utilizes an ammo box containing 1,500 units. Ensure the selected configuration matches the required assembly process and quantity needs before finalizing procurement orders.

Single Diodes Selection Notes

Select this component for designs requiring a 50 V reverse voltage rating and 2 A continuous forward current capability. The 50 ns reverse recovery time makes it suitable for high-frequency switching environments. Verify that the thermal management design accommodates the 60 °C/W junction-to-ambient thermal resistance to maintain safe operating temperatures within the specified range.

Single Diodes Part Context

This part belongs to the HER20xG-T series, which includes variants ranging from 50 V to 600 V reverse voltage ratings. All members of this family share identical mechanical dimensions and electrical parameters except for the breakdown voltage and associated forward voltage characteristics. The series is designed as a general-purpose fast recovery rectifier solution for power conversion systems.

Single Diodes Replacement Considerations

Direct substitutes within the same series include HER202G-T through HER206G-T, provided the circuit voltage requirements exceed 50 V. Cross-manufacturer replacements must match the DO-204AC package, 2 A current rating, and 50 ns reverse recovery specifications to ensure functional compatibility.
