Product details
Overview
HS3F R7G from Taiwan Semiconductor is a 3A, 300V high-efficiency surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring low forward voltage drop (1.0 V @ 3A, 25°C), 150A peak surge current capability, and 50 ns reverse recovery time - used for high-frequency freewheeling and SMPS output rectification in telecom power supplies.
For engineers reviewing the HS3F R7G datasheet, HS3F R7G pinout, HS3F R7G application, or HS3F R7G equivalent, key selection criteria include repetitive peak reverse voltage (300 V), thermal resistance (60 °C/W), junction capacitance (80 pF), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance for industrial-grade power conversion designs.
Technical Context
This device is a single-die, glass-passivated, planar-junction silicon rectifier optimized for switching-mode power supply (SMPS) secondary-side rectification and freewheeling paths where fast recovery and low conduction loss are critical. It operates across -55°C to +150°C junction temperature range with 150A non-repetitive surge rating.
Its 50 ns reverse recovery time and 80 pF junction capacitance at 1 MHz / 4 V support stable operation in 100–500 kHz DC-DC converters. The DO-214AB (SMC) package enables automated placement and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - maximum repetitive reverse blocking voltage; defines safe operating margin in 24–48 V output SMPS with transient clamping |
| IF | 3 A continuous - average forward current rating at TA = 75°C; supports 36 W output at 12 V with 0.5 W conduction loss |
| VF | 1.0 V @ 3 A, 25°C - low forward drop reduces conduction loss vs. standard rectifiers; improves efficiency by ~0.8% at full load |
| trr | 50 ns - fast recovery minimizes switching loss and EMI in high-frequency converters; compatible with synchronous rectifier timing windows |
| RθJA | 60 °C/W - thermal resistance enables 3 A operation on 1-in² 2-oz copper without forced air cooling |
| CJ | 80 pF @ 1 MHz, 4 V - low junction capacitance limits displacement current during turn-off; reduces gate drive loading in flyback snubbers |
| IR | 10 µA @ 300 V, 25°C - low leakage preserves hold-up time in standby mode; critical for energy-efficient PSUs meeting Level VI |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, single-anode/single-cathode configuration. Cathode indicated by molded band. Matte tin-plated leads, J-STD-002 solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead 1) | Forward current entry | Connected to transformer secondary or switch node; must handle 150 A surge without bond wire lift |
| Cathode (lead 2) | Forward current exit / reverse blocking terminal | Connected to output capacitor; cathode band orientation ensures correct PCB polarity alignment during automated assembly |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in industrial environments |
| Moisture sensitivity level 1 | Zero bake requirement before reflow; supports direct placement into high-volume SMT lines without dry pack handling |
| Low profile SMC package | 1.7 mm max height allows use in space-constrained telecom modules and slim AC-DC adapters |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS; eliminates brominated flame retardants for safer end-of-life recycling |
Applications
| Telecom AC-DC Adapters | Server PSU Secondary Rectification |
|---|---|
Use Scenario: 48 V output stage in 300 W telecom adapter operating at 250 kHz. IC Role / Device Role / Timing Role: Output rectifier diode replacing Schottky in cost-sensitive design where 300 V VR rating suffices.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L03S | 3 A, 300 V, VF = 1.05 V @ 3 A, trr = 45 ns, DO-214AB | Slightly faster recovery but higher VF; requires tighter thermal layout due to lower RθJA (55 °C/W) | Prefer when minimizing switching loss dominates over conduction loss; verify layout thermal margin. |
| MBR330CT | 3 A, 30 V dual Schottky, VF = 0.55 V @ 3 A, no trr spec, DO-214AB | Lower VF but insufficient VR rating for 300 V systems; only usable in ≤48 V outputs | Select only for low-voltage (<36 V) applications where ultra-low VF justifies reduced voltage margin. |
Compared with STTH3L03S and MBR330CT, HS3F R7G delivers optimal balance of 300 V robustness, 1.0 V conduction loss, and 50 ns recovery for mid-voltage SMPS - making it preferred for telecom and industrial 24–48 V systems where VR margin and thermal simplicity matter most.

FAQ
What is the maximum junction temperature rating for HS3F R7G?
The HS3F R7G has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed telecom chassis or industrial enclosures. Derating begins above 75°C ambient, and the device maintains full 3 A current capability up to 75°C with standard PCB copper area. Thermal design must respect the 60 °C/W junction-to-ambient resistance to avoid exceeding TJ MAX under sustained load.
Does HS3F R7G meet RoHS and halogen-free requirements?
Yes, HS3F R7G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated or chlorinated flame retardants, and lead content is below 1000 ppm. This is confirmed in the official TSC product specification document K2102 and supported by material declarations available through authorized distributors. Compliance applies to both the die and package materials.
What is the reverse recovery time (trr) of HS3F R7G and how is it measured?
The reverse recovery time (trr) of HS3F R7G is 50 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC test method. This value is specified for the HS3A–HS3G subgroup and applies directly to HS3F R7G. The measurement reflects behavior in high-frequency switching circuits and is critical for minimizing turn-off losses and EMI generation in SMPS designs operating above 100 kHz.
Is HS3F R7G suitable for use in automotive applications?
No, HS3F R7G is not qualified for automotive applications. Taiwan Semiconductor explicitly states in its notice that "The products shown herein are not designed for use in medical, life-saving, or life-sustaining applications." It lacks AEC-Q101 qualification, automotive-grade PPAP documentation, and extended temperature validation beyond -55°C to +150°C. For automotive power systems, engineers should select AEC-Q101-certified alternatives with validated reliability data.
What packaging and reel quantity is available for HS3F R7G?
HS3F R7G is supplied in DO-214AB (SMC) package on tape-and-reel format with 3,000 units per reel, as specified in the ordering information section of the TSC datasheet K2102. The reel meets EIA-481-D standards and is compatible with standard pick-and-place equipment. No alternate packaging (e.g., bulk or ammo pack) is offered for this part number.
