Product details
Overview
S2GFSH from Taiwan Semiconductor is a 2 A, 400 V standard surface-mount silicon rectifier diode in SOD-128 package, featuring glass-passivated junction, AEC-Q101 qualification, and 50 A surge rating (8.3 ms), used for freewheeling and snubber functions in automotive DC/DC converters.
For engineers reviewing the S2GFSH datasheet, S2GFSH pinout, S2GFSH application, or S2GFSH equivalent, key selection criteria include repetitive peak reverse voltage (400 V), forward voltage at 2 A (0.98 V max @ 25°C), junction-to-lead thermal resistance (14 °C/W), moisture sensitivity level (J-STD-020 Level 1), and AEC-Q101 qualification for automotive reliability.
Technical Context
The S2GFSH is a single-die, unidirectional silicon rectifier optimized for high-reliability surface-mount operation. Its glass-passivated junction ensures stable reverse leakage (<1 µA @ 25°C, <33 µA @ 125°C) and robustness against humidity and mechanical stress.
Thermal performance is defined with reference to a 5 mm × 5 mm copper pad PCB: RθJL = 14 °C/W enables efficient heat transfer to the PCB lead frame, while RθJA = 74 °C/W reflects ambient-limited dissipation under standard test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse voltage the device blocks without breakdown; defines usable DC bus or snubber voltage range. |
| IF | 2 A - Continuous average forward current rating at TA = 25°C; derates linearly above 25°C per Fig.1. |
| IFSM | 50 A (8.3 ms) - Peak non-repetitive surge current capability; supports transient energy absorption in flyback or clamp circuits. |
| VF @ 2 A, 25°C | 0.98 V max - Forward conduction loss at rated current; directly impacts power dissipation (Pcond ≈ 1.96 W). |
| RθJL | 14 °C/W - Junction-to-lead thermal resistance; determines temperature rise from die to solder joint under steady-state conduction. |
| Junction Temp Range | –55°C to +150°C - Operating and storage temperature envelope; validated for under-hood automotive environments. |
Pinout & Package
Package: SOD-128 - Low-profile, surface-mount plastic package with matte tin-plated leads, UL 94V-0 molding compound, cathode indicated by band, MSL Level 1, weight ≈ 0.027 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of load or switch node; must handle full IF and IFSM current paths. |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; connects to higher-potential rail; sustains up to 400 V reverse bias during off-state. |
Key Features
| Feature | Design Value |
|---|---|

| Low-profile SOD-128 package | Enables high-density PCB layouts and compatibility with automated pick-and-place equipment (IPC-J-STD-020 compliant). |
| Junction capacitance (12 pF) | Minimizes switching noise and EMI in high-frequency snubber and freewheeling applications (measured at 1 MHz, 4 V). |
Applications
| Automotive DC/DC Converters | Industrial Snubber Circuits |
|---|---|
Use Scenario: Step-down conversion in 12 V/48 V dual-battery systems with synchronous rectification or passive flyback topologies. IC Role / Device Role / Timing Role: Freewheeling diode providing current path during high-side switch off-time; handles 2 A continuous and 50 A surge currents. Use Value: AEC-Q101 qualification and 150°C junction rating ensure operational stability in engine bay thermal environments. | Use Scenario: RC snubber across IGBT or MOSFET switches in motor drives and power supplies to suppress voltage spikes. IC Role / Device Role / Timing Role: Clamp diode absorbing inductive kickback energy; leverages low CJ (12 pF) and fast recovery inherent to standard rectifier structure. Use Value: Glass-passivated junction prevents parameter drift under repeated voltage transients and humidity exposure. |
| On-Board Charger (OBC) Auxiliary Supplies | LED Driver Flyback Outputs |
Use Scenario: Auxiliary 12 V supply generation from main HV DC link in EV on-board chargers. IC Role / Device Role / Timing Role: Output rectifier in isolated flyback or forward converter; operates continuously at 2 A with minimal conduction loss (VF ≤ 0.98 V). Use Value: RθJL = 14 °C/W enables direct thermal coupling to PCB copper, reducing heatsink requirements. | Use Scenario: Secondary-side rectification in constant-current LED drivers for commercial lighting with wide input voltage range. IC Role / Device Role / Timing Role: Main output rectifier handling pulsed LED current; benefits from low IR (≤1 µA @ 25°C) to minimize standby leakage. Use Value: Halogen-free and RoHS-compliant construction meets environmental compliance for global lighting standards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R04 | Same IF (2 A), same VRRM (400 V), but TO-220AC package (not SMD); higher RθJA (50 °C/W), no AEC-Q101. | Requires through-hole mounting and heatsinking; unsuitable for space-constrained or automotive SMT designs. | Select only if board layout allows through-hole assembly and thermal mass compensates for higher RθJA. |
| SB240-E3/5BT | Same SOD-128 package, IF = 2 A, VRRM = 400 V, but not AEC-Q101 qualified; IR = 5 µA @ 25°C (vs. 1 µA for S2GFSH). | Lacks automotive qualification; higher reverse leakage may affect efficiency in low-power standby stages. | Acceptable for industrial or consumer DC/DC where AEC-Q101 is not mandated and leakage tolerance >1 µA. |
Compared with STTH2R04 and SB240-E3/5BT, the S2GFSH uniquely combines SMD SOD-128 packaging, AEC-Q101 qualification, and industry-leading 1 µA max reverse leakage at 25°C-making it the preferred choice for automotive and thermally constrained high-reliability rectification.

FAQ
What is the maximum junction temperature rating for the S2GFSH?
The S2GFSH has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table and supported by thermal characterization data. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. The S2GFSH must be operated within this limit under all conditions-including surge events-to maintain long-term reliability and avoid parametric shift.
Is the S2GFSH pin-compatible with other devices in the S2xFSH series?
Yes-the entire S2xFSH series (S2DFSH to S2MFSH) shares identical SOD-128 package dimensions, pinout, and thermal pad layout. The S2GFSH uses the same anode/cathode terminal configuration and marking orientation as S2DFSH, S2JFSH, and others. No PCB redesign is needed when substituting within the series for voltage rating changes, provided layout accommodates worst-case thermal and voltage isolation requirements.
Does the S2GFSH meet automotive qualification standards?
Yes-the S2GFSH is explicitly AEC-Q101 qualified, as stated in the official Taiwan Semiconductor datasheet Version B2103. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), confirming suitability for automotive powertrain and body electronics applications.
What is the forward voltage drop of the S2GFSH at 2 A and 125°C?
The S2GFSH exhibits a forward voltage drop of 0.88 V (typical) and 0.98 V (maximum) at IF = 2 A and TJ = 125°C, per the Electrical Specifications table. This elevated VF versus room-temperature values reflects increased intrinsic carrier concentration and reduced barrier potential at high junction temperatures-critical for thermal design margining in sustained high-load operation.
How is moisture sensitivity classified for the S2GFSH?
The S2GFSH is rated Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/85% RH and requires no baking prior to reflow soldering. This classification results from the UL 94V-0 molding compound and hermetic glass passivation, eliminating moisture ingress risk during standard SMT assembly processes.
