Product details
Overview
HS3M R7G from Taiwan Semiconductor is a 1000 V, 3 A high-efficiency surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.7 V max forward voltage at 3 A and 75 ns reverse recovery time; used for high-voltage freewheeling and output rectification in telecom SMPS.
For engineers reviewing the HS3M R7G datasheet, HS3M R7G pinout, HS3M R7G application, or HS3M R7G equivalent, key selection criteria include peak reverse voltage rating (1000 V), surge current capability (150 A), thermal resistance (60 °C/W), junction temperature range (−55 to +150 °C), and RoHS/halogen-free compliance.
Technical Context
This device is a single-die, glass-passivated, planar-junction silicon rectifier optimized for high-frequency switching applications. Its 75 ns reverse recovery time and low junction capacitance (50 pF at 4 V) support efficient operation in 100–500 kHz SMPS topologies.
The DO-214AB (SMC) package provides robust thermal performance (RθJA = 60 °C/W) and moisture sensitivity level 1 handling, with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600 V VRRM, 3 A, 50 ns trr, TO-277A package | Limited to ≤600 V systems; faster recovery but lower voltage margin | Select when 600 V rating suffices and faster switching is prioritized over voltage headroom |
| ON Semi MUR3100 | 1000 V VRRM, 3 A, 100 ns trr, DO-201AD package | Higher trr increases switching loss; axial lead limits automated assembly | Choose only if through-hole mounting is required and 75 ns trr is not critical |
Compared with STTH3L06S and MUR3100, HS3M R7G uniquely delivers 1000 V blocking with 75 ns recovery in a surface-mount SMC package-offering optimal balance of voltage margin, switching speed, and manufacturability for modern telecom and industrial SMPS.

FAQ
What is the maximum repetitive peak reverse voltage rating for HS3M R7G?
The HS3M R7G has a maximum repetitive peak reverse voltage (VRRM) of 1000 V, verified per Taiwan Semiconductor's K2102 datasheet revision. This rating allows the HS3M R7G to safely block DC link voltages up to 1000 V in photovoltaic inverters and telecom offline converters, with built-in margin against line surges and transients.
Does HS3M R7G meet RoHS and halogen-free requirements?
Yes, HS3M R7G is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the official Taiwan Semiconductor datasheet (Version K2102). The HS3M R7G uses lead-free matte tin plating and halogen-free molding compound, making it suitable for environmentally regulated end equipment including EU CE-marked telecom infrastructure.
What is the forward voltage drop of HS3M R7G at rated current?
The HS3M R7G exhibits a maximum forward voltage (VF) of 1.7 V at 3 A and 25°C junction temperature, per electrical specifications in the K2102 datasheet. This value is measured under pulsed conditions (PW = 0.3 ms), and actual VF in continuous operation will rise slightly with increasing junction temperature, remaining within design-safe limits up to +150°C.
What package type does HS3M R7G use, and what are its key mechanical features?
HS3M R7G uses the DO-214AB (SMC) surface-mount package, with cathode polarity marked by a molded band. Key mechanical features include UL 94V-0 flammability-rated molding compound, J-STD-002-compliant matte tin-plated leads, JESD 201 Class 2 whisker resistance, and moisture sensitivity level 1-enabling direct placement without pre-bake.
How does the reverse recovery time of HS3M R7G compare to lower-voltage variants in the HS3x family?
HS3M R7G has a maximum reverse recovery time (trr) of 75 ns, consistent with HS3J, HS3K, and HS3M variants per the K2102 datasheet. This is higher than HS3A–HS3G (50 ns), reflecting the trade-off between higher voltage capability and minority carrier lifetime control; the 75 ns trr remains suitable for 100–300 kHz SMPS designs using the HS3M R7G.
