Product details
Overview
RS2GFSH from Taiwan Semiconductor is a 2 A, 400 V fast recovery surface-mount rectifier in SOD-128 package, featuring 150 ns reverse recovery time, 1.01 V forward voltage at 2 A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in DC/DC converters where low conduction loss and fast switching are critical.
For engineers reviewing the RS2GFSH datasheet, RS2GFSH pinout, RS2GFSH application, or RS2GFSH equivalent, key selection criteria include its 400 V VRRM, 150 ns trr, glass-passivated junction, moisture sensitivity level 1 rating, and suitability for automated SMT assembly in space-constrained power stages.
Technical Context
The RS2GFSH employs a single-die silicon PN junction with glass passivation for enhanced reliability and humidity resistance. Its fast recovery performance (trr ≤ 150 ns) enables high-frequency operation in switching power supplies without excessive switching loss.
Thermally, it delivers RθJL = 16 °C/W and RθJA = 73 °C/W on a 5 mm × 5 mm Cu pad, supporting continuous 2 A operation up to 175 °C junction temperature while maintaining low profile and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 400 V-rated DC bus or flyback clamp circuits. |
| IF | 2 A - Continuous forward current rating; supports sustained conduction in medium-power rectification paths. |
| trr | ≤150 ns - Fast reverse recovery time; minimizes switching loss and EMI in 100–500 kHz DC/DC topologies. |
| VF @ 2A/25°C | 1.01 V - Low forward voltage drop; reduces conduction loss and thermal stress under full-load conditions. |
| RθJL | 16 °C/W - Junction-to-lead thermal resistance; enables direct PCB copper pad heat sinking without additional heatsink. |
| MSL | Level 1 (per J-STD-020) - No floor life limitation; allows indefinite storage and standard reflow without baking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R04S | Same 2 A / 400 V rating, but TO-277 package (larger footprint, higher RθJA = 90 °C/W). | Less suitable for ultra-thin designs; requires larger PCB area and may need thermal relief. | Choose STTH2R04S only if legacy TO-277 layout exists and thermal margin exceeds 20 °C. |
| ON Semi MUR240 | 2 A / 400 V, but slower trr = 35 ns typical (not guaranteed ≤150 ns), no AEC-Q101 qualification. | Not recommended for automotive; acceptable in industrial non-safety-critical supplies. | Select MUR240 only when AEC-Q101 is not required and cost is primary driver. |
Compared with STTH2R04S and MUR240, RS2GFSH uniquely combines AEC-Q101 qualification, SOD-128 low-profile packaging, and guaranteed ≤150 ns trr-making it optimal for next-gen automotive and space-constrained industrial power stages where reliability, size, and speed are jointly constrained.

FAQ
What is the maximum junction temperature rating for RS2GFSH?
The RS2GFSH has a maximum junction temperature (TJMAX) of +175 °C, verified per absolute maximum ratings table. This allows continuous operation in underhood automotive environments and high-ambient industrial settings. Derating begins above 125 °C ambient, and thermal design must respect RθJL = 16 °C/W to maintain RS2GFSH junction temperature within limit under 2 A load.
Is RS2GFSH pin-compatible with other devices in the RS2xFSH series?
Yes, all RS2xFSH variants-including RS2DFSH, RS2GFSH, RS2JFSH, RS2KFSH, and RS2MFSH-share identical SOD-128 package dimensions, pinout, and thermal pad layout. The only differences are VRRM (200–1000 V) and trr (150–500 ns), allowing direct substitution based on voltage and speed requirements without PCB changes.
Does RS2GFSH meet automotive qualification standards?
Yes, RS2GFSH is explicitly AEC-Q101 qualified per the manufacturer's datasheet revision C2304. This includes stress testing for temperature cycling, humidity bias, mechanical shock, and solderability-validating its use in automotive powertrain, chassis, and body electronics where functional safety and long-term reliability are mandatory.
What is the reverse recovery time (trr) specification for RS2GFSH?
The RS2GFSH has a maximum reverse recovery time (trr) of 150 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is guaranteed across temperature and ensures minimal switching loss in high-frequency DC/DC converters. Typical trr is lower, but design margins should use the 150 ns max value for worst-case analysis of RS2GFSH performance.
How is polarity indicated on the RS2GFSH package?
Polarity on the RS2GFSH is indicated by a visible cathode band on the SOD-128 package body, aligned with the cathode terminal. Per mechanical data, this band corresponds to the terminal marked "CATHODE INDICATOR" in the marking diagram. Correct orientation is essential: anode must connect toward lower potential (e.g., switch node), cathode toward higher potential (e.g., output rail) to ensure proper rectification and avoid device failure.
