Product details
Overview
HS2DFSH from Taiwan Semiconductor is a 2 A, 200 V glass-passivated surface-mount fast recovery rectifier in SOD-128 package, featuring 50 ns reverse recovery time, 0.87 V forward voltage at 2 A/25°C, and AEC-Q101 qualification for automotive use in DC/DC converters and freewheeling circuits.
For engineers reviewing the HS2DFSH datasheet, HS2DFSH pinout, HS2DFSH application, or HS2DFSH equivalent, key selection criteria include its 200 V VRRM, 60 A IFSM, 17 °C/W RθJL, JESD201 Class 2 whisker resistance, and moisture sensitivity level 1 compliance.
Technical Context
The HS2DFSH is a single-die, low-profile fast recovery rectifier optimized for high-efficiency switching applications. Its 50 ns trr and 0.87 V VF at 2 A/25°C enable reduced switching losses in high-frequency DC/DC topologies.
Designed with glass-passivated junction and matte tin-plated leads, it supports automated placement and meets AEC-Q101 stress requirements. Thermal performance is characterized with RθJL = 17 °C/W on a 5 mm × 5 mm Cu pad PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for blocking capability in snubber or freewheeling paths. |
| IF | 2 A - Continuous forward current rating; defines steady-state conduction capacity in power supply output stages. |
| IFSM | 60 A - Non-repetitive surge current (8.3 ms); supports inrush and transient overload handling without failure. |
| trr | 50 ns - Reverse recovery time; enables operation up to ~3 MHz switching frequencies with minimal commutation loss. |
| VF | 0.87 V @ 2 A, 25°C - Forward voltage drop; directly determines conduction loss (Pcond ≈ IF × VF) in high-current paths. |
| RθJL | 17 °C/W - Junction-to-lead thermal resistance; enables accurate thermal design when mounted on PCB copper pads. |
| CJ | 32 pF @ 1 MHz, 4 V - Junction capacitance; impacts high-frequency switching noise and EMI filtering requirements. |
Pinout & Package
Package: SOD-128 - Low-profile, surface-mount plastic package with cathode band polarity marking; 0.028 g weight; UL 94V-0 rated molding compound; JESD201 Class 2 whisker-resistant matte tin leads.
| 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 point | Marked by band; connects to higher-potential rail (e.g., output capacitor positive); critical for correct orientation in automated assembly. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and UHAST - required for under-hood and ADAS power modules. |
| Glass-passivated junction | Provides robust protection against humidity and contamination, enabling stable long-term operation in harsh environments. |
| 50 ns reverse recovery time | Reduces turn-off switching loss and diode ringing in high-frequency SMPS, improving efficiency over standard FRDs. |
| Moisture Sensitivity Level 1 | Eliminates bake requirement prior to reflow; compatible with standard SMT assembly processes without floor-life constraints. |
| Low profile SOD-128 package | Enables compact board layout in space-constrained automotive ECUs and portable power adapters. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02FL | 2 A, 200 V, 50 ns trr, TO-277A package (larger footprint, higher RθJA) | Requires larger PCB area and has higher thermal resistance (RθJA ≈ 70 °C/W vs. 53 °C/W) | Prefer HS2DFSH where board space and thermal performance on small pads are critical. |
| ON Semi MUR220S | 2 A, 200 V, 60 ns trr, SMA package (smaller current handling, no AEC-Q101) | Lacks automotive qualification and has higher VF (0.95 V) and slower recovery | Acceptable for non-automotive consumer adapters but not for AEC-Q101-compliant designs. |
Compared with STTH2R02FL and MUR220S, the HS2DFSH delivers superior thermal performance in compact form factor and is the only AEC-Q101-qualified option among the three-making it the preferred choice for automotive and high-reliability industrial power stages.

FAQ
What is the maximum junction temperature rating for HS2DFSH?
The HS2DFSH has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating allows reliable operation in under-hood automotive environments and thermally constrained industrial enclosures. Derating curves confirm usable current capacity down to -55°C ambient, and thermal design must account for RθJL = 17 °C/W when mounted on a 5 mm × 5 mm copper pad. The HS2DFSH maintains stable electrical characteristics across this full range.
Is HS2DFSH suitable for automotive applications?
Yes, the HS2DFSH is explicitly AEC-Q101 qualified, meeting stress test requirements for temperature cycling, high-temperature reverse bias, and unbiased high-humidity aging. Its glass-passivated junction, JESD201 Class 2 whisker resistance, and moisture sensitivity level 1 make it suitable for engine control units, ADAS power supplies, and body electronics. The HS2DFSH is designed and tested for automotive-grade reliability-not just recommended.
What does the "D" in HS2DFSH indicate?
The "D" in HS2DFSH denotes the 200 V VRRM rating within the HS2xFSH family, where "D" = 200 V, "G" = 400 V, "J" = 600 V, "K" = 800 V, and "M" = 1000 V. This coding is defined in the ordering information section of the datasheet and applies exclusively to the exact part number HS2DFSH. No other voltage variants share the same electrical specifications or thermal performance.
What is the forward voltage of HS2DFSH at 2 A and 125°C?
The HS2DFSH exhibits a typical forward voltage of 0.74 V and a maximum of 0.82 V at 2 A and 125°C, per the Electrical Specifications table. This lower VF at elevated temperature reflects the negative temperature coefficient of silicon PN junctions and supports stable performance in thermally demanding applications. These values are measured under pulsed conditions (PW = 0.3 ms) and are confirmed for the HS2DFSH variant only.
Does HS2DFSH have a specified junction capacitance value?
Yes, the HS2DFSH has a typical junction capacitance (CJ) of 32 pF measured at 1 MHz and 4.0 V reverse bias, as stated in the Electrical Specifications table. This parameter is critical for high-frequency switching noise analysis and EMI filter design. CJ decreases with increasing reverse voltage and varies across the HS2xFSH family-HS2GFSH is 25 pF, HS2JFSH is 17 pF-so the 32 pF value applies solely to HS2DFSH.
