Product details
Overview
HS2GFS from Taiwan Semiconductor is a 2 A, 400 V glass-passivated surface-mount fast recovery rectifier in SOD-128 package, featuring 0.99 V forward voltage at 2.0 A / 25°C, 50 ns reverse recovery time, and 25 pF junction capacitance - deployed in DC-DC converters and switching inverters requiring efficient freewheeling.
For engineers reviewing the HS2GFS datasheet, HS2GFS pinout, HS2GFS application, or HS2GFS equivalent, key selection criteria include peak reverse voltage (400 V), thermal resistance (RθJL = 17 °C/W), TJ max (150 °C), IFSM (60 A @ 8.3 ms), and moisture sensitivity level (MSL 1).
Technical Context
The HS2GFS is a single-die, planar epitaxial fast recovery rectifier with glass-passivated junction for enhanced reliability and moisture resistance. Its 50 ns trr and low Qrr support high-frequency switching in SMPS topologies.
Thermal performance is defined by RθJL = 17 °C/W and RθJA = 53 °C/W on a 5 mm × 5 mm Cu pad PCB, enabling sustained 2 A conduction at up to 150 °C junction temperature under proper layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling paths |
| IF | 2 A continuous - rated average forward current; supports compact power stage designs without forced cooling |
| trr | 50 ns - fast reverse recovery enables >100 kHz switching in DC-DC converters with low switching loss |
| VF @ 2A/25°C | 0.99 V (max 1.30 V) - low conduction loss improves efficiency in high-duty-cycle applications |
| CJ | 25 pF @ 1 MHz / 4 V - reduced capacitive loading minimizes EMI and gate drive burden in synchronous rectification |
| RθJL | 17 °C/W - low junction-to-lead thermal resistance allows direct heat transfer to PCB copper, easing thermal design |
| IFSM | 60 A @ 8.3 ms - surge rating supports inrush and transient overload conditions in industrial power supplies |
Pinout & Package
Package: SOD-128 - low-profile, surface-mount plastic package with matte tin-plated leads (J-STD-002 compliant), UL 94V-0 molding compound, and cathode band polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); requires adequate copper area for thermal dissipation |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output rail or ground return; critical for correct orientation in automated placement |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables MSL 1 handling and long-term reliability in humid environments without conformal coating |
| Fast recovery (50 ns) | Reduces switching losses and EMI generation in high-frequency (>100 kHz) SMPS designs |
| Low profile SOD-128 package | Supports ultra-thin power modules and space-constrained board layouts while maintaining thermal performance |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and global environmental regulations for industrial and consumer end equipment |
| 150 °C max junction temperature | Allows operation in sealed enclosures or high-ambient environments without derating below 2 A |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R04 | Same 2 A / 400 V rating; TO-220AC package; higher VF (1.3 V @ 2 A); RθJA = 65 °C/W | Requires heatsink for >1 A continuous; unsuitable for ultra-thin or high-density layouts | Select when mechanical mounting and legacy footprint compatibility outweigh SMT assembly benefits |
| ES2D | SOD-123 package; 2 A / 200 V; 35 ns trr; lower VF (0.92 V); not rated for 400 V systems | Limited to <200 V applications; insufficient reverse margin in 375 V DC bus designs | Select only for cost-sensitive, low-voltage (<200 V) SMPS where 50 ns trr is non-critical |
Compared with STTH2R04 and ES2D, the HS2GFS uniquely balances 400 V blocking, SOD-128 mountability, 50 ns speed, and MSL 1 reliability - making it optimal for space-constrained, high-reliability 24–48 V DC-DC and industrial inverter designs.

FAQ
What is the maximum junction temperature rating for HS2GFS?
The HS2GFS has a maximum junction temperature (TJ) of +150 °C, verified per absolute maximum ratings in the official datasheet. This allows continuous 2 A operation in sealed enclosures or high-ambient environments when mounted on a 5 mm × 5 mm Cu pad. Derating begins above 125 °C ambient, and thermal design must respect RθJL = 17 °C/W to avoid exceeding 150 °C at the die.
Does HS2GFS have a specified reverse recovery time (trr)?
Yes, the HS2GFS has a typical reverse recovery time of 50 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 (Version C2103) and enables efficient operation in switching power supplies operating above 100 kHz without excessive switching loss or EMI.
What is the forward voltage drop of HS2GFS at full rated current?
The HS2GFS exhibits a maximum forward voltage (VF) of 1.30 V at IF = 2.0 A and TJ = 25 °C, with a typical value of 0.99 V. At elevated temperature (125 °C), VF drops to 0.86 V (typ) / 0.96 V (max), reflecting positive temperature coefficient behavior beneficial for current sharing in parallel configurations.
Is HS2GFS RoHS and halogen-free compliant?
Yes, the HS2GFS is fully RoHS compliant and halogen-free per IEC 61249-2-21. The device uses matte tin-plated leads, UL 94V-0 molding compound, and meets JESD 201 Class 2 whisker resistance requirements - ensuring environmental compliance for export to EU, China, and other regulated markets.
What packaging format is used for HS2GFS?
The HS2GFS is supplied in SOD-128 package and shipped in tape-and-reel format containing 14,000 units per reel. The SOD-128 outline features low profile height (<1.1 mm), cathode band polarity marking, and J-STD-002 solderable terminals - optimized for high-speed pick-and-place and reflow soldering in automated manufacturing.
