Product details
Overview
HS3D R7G from Taiwan Semiconductor is a 200 V, 3 A surface-mount high-efficiency fast recovery rectifier diode in DO-214AB (SMC) package, featuring 50 ns reverse recovery time, 1.0 V max forward voltage at 3 A, and 10 µA max reverse leakage at 25°C - used in switching mode power supplies for computer and telecom systems.
For engineers reviewing the HS3D R7G datasheet, HS3D R7G pinout, HS3D R7G application, or HS3D R7G equivalent, key selection criteria include repetitive peak reverse voltage (200 V), forward surge current rating (150 A), junction-to-ambient thermal resistance (60 °C/W), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
This device is a single-die, glass-passivated silicon PN junction rectifier optimized for high-frequency operation. Its fast recovery time (50 ns) and low forward voltage drop enable efficient energy transfer in DC-DC converters and freewheeling paths where switching losses must be minimized.
The DO-214AB (SMC) package supports automated placement and provides robust thermal performance (RθJA = 60 °C/W) with matte tin-plated leads compliant to J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications

|---|---|
| VRRM | 200 V - maximum repetitive reverse voltage the diode blocks without breakdown |
| IF | 3 A continuous average forward current - defines steady-state conduction capability |
| IFSM | 150 A - peak non-repetitive surge current handling for transient overload protection |
| trr | 50 ns - fast reverse recovery enables high-frequency switching up to ~1 MHz |
| VF @ 3 A | ≤1.0 V - low conduction loss reduces heat generation in power stage |
| RθJA | 60 °C/W - thermal resistance determines junction temperature rise under ambient conditions |
| IR @ 25°C | ≤10 µA - low leakage preserves efficiency in high-impedance bias networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L02 | 200 V, 3 A, 50 ns trr, but TO-220AC package (not SMD); higher RθJA (40 °C/W case-to-ambient) | Requires through-hole PCB layout and heatsink mounting; unsuitable for high-density automated assembly | Select when board space allows larger footprint and thermal management uses external heatsink |
| MBR3200CT | 200 V, dual common-cathode Schottky; 0.85 V VF but 100 µA IR at 125°C (vs. 250 µA for HS3D R7G) | Better efficiency at light loads; higher leakage limits use in high-temp (>105°C) environments | Select for <85°C ambient applications prioritizing lowest conduction loss over leakage-limited reliability |
Compared with STTH3L02 and MBR3200CT, the HS3D R7G offers surface-mount compatibility, J-STD-020 Level 1 handling, and balanced trade-off between forward voltage, leakage, and recovery speed for cost-sensitive industrial and telecom power supplies.

FAQ
What is the maximum junction temperature rating for HS3D R7G?
The HS3D R7G has a maximum junction temperature (TJ) of +150°C, allowing reliable operation in demanding thermal environments such as enclosed power supplies or high-ambient industrial enclosures. This rating is validated per JEDEC standards and aligns with its 60 °C/W junction-to-ambient thermal resistance. Derating curves in the HS3D R7G datasheet specify safe operating current limits above 75°C ambient.
Does HS3D R7G meet RoHS and halogen-free requirements?
Yes, the HS3D R7G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. These specifications are confirmed in Taiwan Semiconductor's official compliance documentation for the HS3D R7G family and verified on TSC's product change notices.
What is the reverse recovery time (trr) of HS3D R7G and how is it measured?
The HS3D R7G has a reverse recovery time (trr) of 50 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the manufacturer's test circuit in Figure 6 of the HS3D R7G datasheet. This value reflects performance at 25°C and is representative of its suitability for switching frequencies up to 500 kHz in hard-switched topologies.
Is HS3D R7G suitable for use in automotive applications?
The HS3D R7G is not qualified to AEC-Q101 or automotive-grade reliability standards and is not recommended for safety-critical automotive systems. While its electrical specs (e.g., 150 A IFSM, -55°C to +150°C TSTG) overlap with some automotive requirements, Taiwan Semiconductor explicitly states that HS3D R7G is intended for industrial, computing, and telecom use - not medical, life-saving, or automotive applications.
What does the 'R7G' suffix indicate in HS3D R7G?
The 'R7G' suffix in HS3D R7G denotes Taiwan Semiconductor's internal date code and factory marking: 'R7' indicates week 7 of year 2023 (or 2033), and 'G' identifies the fabrication facility. This is consistent with TSC's standard marking convention shown in the package outline diagram of the HS3D R7G datasheet and does not affect electrical or mechanical specifications.
