Product details
Overview
HS3K V7G from Taiwan Semiconductor is a 800 V repetitive peak reverse voltage, 3 A average forward current, surface-mount high-efficiency rectifier in DO-214AB (SMC) package, featuring 1.7 V max forward voltage at 3 A and 75 ns max reverse recovery time, used in switching mode power supplies for telecom infrastructure.
For engineers reviewing the HS3K V7G datasheet, HS3K V7G pinout, HS3K V7G application, or HS3K V7G equivalent, key selection criteria include VRRM=800 V, IF=3 A, VF≤1.7 V @ 3 A, trr≤75 ns, and DO-214AB thermal resistance RθJA=60 °C/W.
Technical Context
This device is a single-die, glass-passivated silicon junction rectifier optimized for high-frequency switching applications. It operates with junction temperature range –55°C to +150°C and meets J-STD-020 moisture sensitivity level 1.
The HS3K V7G exhibits low-profile mechanical construction with matte tin-plated leads, UL 94V-0 molding compound, and cathode band polarity indication. Its 50 pF typical junction capacitance at 1 MHz and 4 V reverse bias supports fast transient response in SMPS flyback and forward converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - maximum repetitive reverse blocking voltage; defines safe operating limit in high-voltage DC bus clamping |
| IF(AV) | 3 A - continuous average forward current; determines steady-state power handling in rectification stage |
| VF(max) | 1.7 V @ 3 A, 25°C - forward conduction loss directly impacts efficiency and thermal design in 100–500 kHz converters |
| trr(max) | 75 ns - reverse recovery time; critical for minimizing switching losses and EMI in high-frequency SMPS |
| RθJA | 60 °C/W - junction-to-ambient thermal resistance; enables thermal estimation without heatsink under natural convection |
| CJ(typ) | 50 pF @ 1 MHz, 4 V - junction capacitance affects high-frequency noise coupling and snubber design |
| IFSM | 150 A @ 8.3 ms - non-repetitive surge rating; supports inrush current tolerance during power-up |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, single-anode/single-cathode configuration, cathode indicated by molded band. Weight: 0.210 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction path | Connected to AC input or switch node; must withstand full reverse voltage when off |
| Cathode | Output terminal for forward conduction path | Connected to output capacitor or load; carries full forward current and defines output polarity |
Key Features

Applications
| Telecom AC-DC Power Supplies | Industrial Motor Drive Freewheeling |
|---|---|
Use Scenario: Rectifying 380 VAC input in 1 kW telecom rectifier modules with >92% efficiency target. IC Role / Device Role / Timing Role: Primary-side high-voltage rectifier in bridge or PFC front-end stage. Use Value: 800 V VRRM safely handles 380 VAC × √2 × 1.2 margin; 75 ns trr reduces switching loss vs. slower rectifiers. | Use Scenario: Clamp inductive kickback from 48 V BLDC motor phase windings in factory automation drives. IC Role / Device Role / Timing Role: Freewheeling diode across IGBT/MOSFET switches in H-bridge output stage. Use Value: 150 A IFSM withstands motor stall surges; low VF minimizes conduction loss during extended freewheeling periods. |
| Server PSU Secondary-Side Rectification | Renewable Energy Inverter DC Link Protection |
Use Scenario: Output rectification in 12 V/200 A server power supply using synchronous topology with discrete diode backup. IC Role / Device Role / Timing Role: OR-ing or redundancy diode in parallel VRM outputs or hold-up circuitry. Use Value: 3 A IF rating supports auxiliary rail loads; DO-214AB footprint allows dense layout near point-of-load regulators. | Use Scenario: Reverse-polarity protection and DC link clamping in 600 V solar string inverters. IC Role / Device Role / Timing Role: Bidirectional blocking element in DC bus overvoltage crowbar or anti-islanding detection path. Use Value: 800 V VRRM exceeds 600 V DC link with safety margin; 250 µA IR @ 125°C ensures low leakage at elevated ambient temperatures. |
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 | VRRM = 600 V, VF = 1.7 V @ 3 A, trr = 50 ns, DO-214AB | Limited to ≤600 V systems; faster recovery but lower voltage rating | Select when system VR < 600 V and trr < 60 ns is prioritized over voltage margin |
| MBR360FCT | VRRM = 60 V, VF = 0.75 V @ 3 A, Schottky, TO-277 | Lower VF but insufficient VRRM for 800 V use; incompatible voltage class | Only suitable for low-voltage (<100 V) high-efficiency applications; not a voltage-class substitute |
Compared with STTH3L06S and MBR360FCT, the HS3K V7G uniquely balances 800 V blocking capability with 75 ns recovery and SMC packaging-enabling compact, high-reliability rectification where voltage margin and thermal robustness are critical.

FAQ
What is the maximum junction temperature rating for HS3K V7G?
The HS3K V7G has a maximum junction temperature (TJ) rating of +150°C, with operational range from –55°C to +150°C. This rating enables reliable operation in high-ambient environments such as enclosed telecom rectifiers or industrial motor drive cabinets. Derating curves in the datasheet specify reduced IF above 75°C ambient, and the device's RθJA of 60 °C/W supports thermal modeling without forced airflow.
Does HS3K V7G meet RoHS and halogen-free requirements?
Yes, the HS3K V7G is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound is UL 94V-0 rated, and terminals are matte tin plated to meet J-STD-002 solderability and JESD 201 Class 2 whisker resistance standards. These qualifications make HS3K V7G suitable for export to EU, Japan, and other environmentally regulated markets.
What is the reverse recovery time (trr) specification for HS3K V7G?
The HS3K V7G has a maximum reverse recovery time (trr) of 75 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the Electrical Specifications table on page 2 of the official TSC datasheet (Version K2102). The 75 ns trr supports efficient operation in 100–500 kHz switching converters while limiting switching loss and EMI generation.
Is HS3K V7G pin-compatible with other devices in the HS3x series?
Yes, all HS3x devices-including HS3K V7G-share identical DO-214AB (SMC) package dimensions, pinout, and thermal pad layout. The anode and cathode terminals are physically and electrically consistent across the series; only VRRM, VF, and trr vary by suffix (A through M). This allows direct board-level substitution when voltage and performance requirements align.
What does the 'V7G' suffix indicate in HS3K V7G?
The 'V7G' suffix in HS3K V7G is Taiwan Semiconductor's internal date and process code: 'V' denotes wafer lot year (2022), '7' indicates calendar week (week 7), and 'G' identifies the fabrication line or process variant. It does not affect electrical specifications-HS3K V7G retains the full HS3K parametric profile: VRRM = 800 V, IF = 3 A, VF ≤ 1.7 V, trr ≤ 75 ns.
