HS3K R7G

Single Diodes Overview

The HS3K R7G is a high-efficiency fast recovery rectifier manufactured by Taiwan Semiconductor Corporation. It features a single-phase, one-element silicon construction housed in the DO-214AB (SMC) surface-mount package. The device is rated for a maximum repetitive reverse voltage of 800V and an average forward current of 3A. Key electrical specifications include a maximum forward voltage of 1.7V, a reverse leakage current of 10µA, and a maximum non-repetitive peak surge current of 150A. The component exhibits a fast recovery time of 75ns and operates within a junction temperature range from -55°C to +150°C.

Single Diodes Procurement Notes

Verify the specific ordering suffix R7G against the manufacturer's official datasheet to confirm tape-and-reel packaging details. Confirm RoHS compliance status as indicated in product documentation. Check for the Not Recommended for New Design (NRND) status to assess long-term availability and lifecycle implications before finalizing procurement plans.

Single Diodes Selection Notes

Select this component when a surface-mount fast recovery rectifier with 800V blocking capability and 3A continuous current rating is required. Ensure the DO-214AB footprint matches the PCB layout constraints. Verify that the 75ns recovery time meets the switching speed requirements of the target circuit design compared to standard rectifiers.

Single Diodes Part Context

This part belongs to the HS3K series of surface mount fast recovery rectifiers from Taiwan Semiconductor. The series utilizes glass passivation technology and plastic molding for durability. The R7G suffix typically denotes specific packaging configurations such as tape and reel, distinguishing it from bulk or other reel variants within the same electrical family.

Single Diodes Replacement Considerations

Consult official substitution guides for equivalent 3A, 800V SMC fast recovery diodes. Verify pinout compatibility and thermal performance metrics before replacing. Cross-reference with similar series parts like RS3KR7 only if electrical parameters and physical dimensions are confirmed identical.
