HS3M R6G Equivalent & Substitute Parts

Part Overview

The HS3M R6G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 1000 V DC reverse voltage and 3 A average rectified current in a surface mount DO-214AB (SMC) package. This component is classified as discontinued at DiGi Electronics, necessitating identification of equivalent substitute parts for ongoing procurement and design continuity. The diode features fast recovery characteristics with a reverse recovery time of 75 ns and operates across a junction temperature range of -55°C to 150°C.

Engineering Selection Recommendations

The UF3M_R1_00001 from Panjit International Inc. is a direct parametric equivalent for the discontinued HS3M R6G. Both components share identical voltage and current ratings, forward voltage characteristics, package configuration, and thermal operating range. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component procurement. The substitute part is supplied in Tape & Reel (TR) packaging format, which is standard for surface mount production environments.

Secondary parameter variations—specifically the reverse recovery time differential (75 ns vs. 100 ns) and improved reverse leakage characteristics (1 µA vs. 10 µA) in the substitute—represent performance enhancements rather than degradation. These variations do not compromise functional compatibility in general-purpose rectification circuits.

Frequently Asked Questions (FAQ)

Q: Can the UF3M_R1_00001 be used as a direct replacement for the HS3M R6G?

A: Yes. Both components are rated for 1000 V DC reverse voltage, 3 A average rectified current, and feature identical forward voltage characteristics at rated current. The DO-214AB (SMC) surface mount package is identical, enabling direct PCB footprint compatibility without design modification.

Q: What is the significance of the reverse recovery time difference (75 ns vs. 100 ns)?

A: The reverse recovery time difference falls within the fast recovery classification (≤ 500 ns) for both parts. This parameter affects switching speed in high-frequency applications. The substitute part's 100 ns recovery time remains suitable for general-purpose rectification and does not introduce functional incompatibility.

Q: Does the lower reverse leakage current in the substitute part affect circuit performance?

A: The substitute part exhibits lower reverse leakage current (1 µA vs. 10 µA at 1000 V), which represents an improvement in leakage characteristics. This does not create compatibility issues and may provide marginal benefits in low-current applications.

Q: Are there packaging differences between the main part and substitute?

A: Both components use the DO-214AB (SMC) surface mount package. The substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly. The physical package dimensions and PCB footprint are identical.

Q: What compliance certifications apply to the substitute part?

A: The UF3M_R1_00001 is ROHS3 compliant and REACH unaffected, matching the regulatory status of the original HS3M R6G. Both components satisfy environmental and hazardous substance restrictions for electronic component procurement.

Q: Is the substitute part currently available?

A: Yes. The UF3M_R1_00001 maintains active product status with 1850 pieces in stock, providing immediate availability compared to the discontinued HS3M R6G.
