Product details
Overview
HS1DFSH from Taiwan Semiconductor is a 1A, 200V high-efficiency surface-mount fast recovery rectifier in SOD-128 package, featuring 50ns reverse recovery time, 0.85V forward voltage at 1.0A/25°C, and AEC-Q101 qualification for automotive use in DC/DC converters and snubber circuits.
For engineers reviewing the HS1DFSH datasheet, HS1DFSH pinout, HS1DFSH application, or HS1DFSH equivalent, key selection criteria include its 200V VRRM, 35A IFSM, 29°C/W RθJL, J-STD-020 Level 1 moisture sensitivity, and SOD-128 low-profile footprint compatibility with automated placement.
Technical Context
The HS1DFSH employs a glass-passivated silicon die optimized for fast switching and low conduction loss, with junction temperature range from –55°C to +150°C and thermal resistance RθJC = 22°C/W. Its single-die configuration supports unidirectional current flow with cathode-band polarity marking.
Electrical behavior is characterized by low forward voltage (0.80V typ. @ 0.5A/25°C), minimal reverse leakage (≤1µA @ 25°C), and tight trr specification of ≤50ns under IF = 0.5A / IR = 1.0A / Irr = 0.25A conditions - enabling high-frequency operation in power conversion stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse voltage before breakdown; defines safe operating limit in flyback or clamp circuits |
| IF | 1 A continuous - rated average forward current; determines thermal design margin on PCB copper area |
| IFSM | 35 A peak (8.3ms) - surge capability for startup or fault transients without failure |
| trr | ≤50 ns - fast recovery enables >100 kHz switching in DC/DC topologies with reduced switching loss |
| VF | 0.85 V max @ 1.0A/25°C - low conduction loss improves efficiency in high-duty-cycle applications |
| RθJL | 29 °C/W - junction-to-lead thermal resistance; enables direct thermal path to PCB copper pad for passive cooling |
| CJ | 20 pF @ 1 MHz, 4 V - low junction capacitance minimizes capacitive coupling noise in high-speed switching nodes |
Pinout & Package
SOD-128 surface-mount package: low-profile, molded plastic case meeting UL 94V-0; matte tin-plated leads compliant with J-STD-002 solderability; polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); must handle full load current and surge |
| Cathode | Forward current exit point | Connected to higher-potential rail (e.g., output capacitor positive); marked by visible band for orientation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| Glass passivated junction | Enhances long-term stability and humidity resistance versus epoxy-passivated alternatives |
| Low profile SOD-128 | Height ≤1.1 mm enables compact layout in space-constrained modules like OBCs and ADAS ECUs |
| J-STD-020 Level 1 | No floor life limitation - can be mounted directly from reel without baking or dry pack handling |
| Halogen-free (IEC 61249-2-21) | Complies with automotive environmental standards and supports lead-free reflow profiles |
Applications
| Freewheeling Diode | Snubber Circuit |
|---|---|
Use Scenario: Used across MOSFET drain-source in buck or flyback converters to provide current path during switch-off. IC Role / Device Role / Timing Role: Freewheeling diode conducting during off-time; critical for energy transfer and voltage clamping. Use Value: 50ns trr and 0.85V VF reduce switching losses and improve light-load efficiency vs. standard recovery diodes. | Use Scenario: Placed across switching devices to absorb voltage spikes caused by parasitic inductance. IC Role / Device Role / Timing Role: Transient voltage clamp; conducts only during nanosecond-scale overvoltage events. Use Value: Low CJ (20 pF) and fast trr minimize ringing and ensure clean turn-off without oscillation. |
| DC/DC Converter Output | Automotive Power Module |
Use Scenario: Output rectification in isolated or non-isolated DC/DC supplies for infotainment or body control units. IC Role / Device Role / Timing Role: Main output rectifier delivering regulated DC; operates continuously at up to 1A average current. Use Value: RθJL = 29°C/W allows thermal management via 5mm × 5mm Cu pad, eliminating need for heatsinks. | Use Scenario: Integrated into engine control units, lighting drivers, or ADAS sensor modules requiring AEC-Q101 compliance. IC Role / Device Role / Timing Role: High-reliability rectifier in harsh environment; exposed to –40°C to +125°C ambient with thermal cycling. Use Value: AEC-Q101 qualification plus –55°C to +150°C TJ rating ensures functional safety in under-hood 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 |
|---|---|---|---|
| STTH1R02FL | VRRM = 200 V, IF = 1 A, trr = 30 ns, VF = 0.95 V max @ 1A - faster but higher forward drop | Better suited for ultra-high-frequency SMPS where trr dominates loss; less optimal for thermally constrained layouts due to higher VF | Select when minimizing switching loss is prioritized over conduction loss and board space permits TO-277 footprint |
| ON Semi MUR120RLG | VRRM = 200 V, IF = 1 A, trr = 75 ns, VF = 0.92 V max @ 1A - slower recovery, higher VF, DO-41 package | Through-hole mounting requires manual assembly or wave soldering; unsuitable for fully SMT automotive modules | Choose only for legacy through-hole designs or cost-sensitive non-automotive applications where speed is secondary |
Compared with STTH1R02FL and MUR120RLG, the HS1DFSH delivers balanced performance: 50ns trr enables high-frequency operation while maintaining low VF and SOD-128 surface-mount compatibility essential for modern automotive electronics miniaturization.

FAQ
What is the maximum junction temperature rating for HS1DFSH?
The HS1DFSH has a maximum junction temperature (TJ) rating of +150°C, with operational range from –55°C to +150°C. This wide thermal window supports deployment in under-hood automotive environments and industrial power supplies where ambient temperatures exceed 105°C. The HS1DFSH maintains specified electrical parameters within this range, and its RθJL = 29°C/W enables reliable thermal dissipation when mounted on a 5mm × 5mm copper pad.
Is HS1DFSH suitable for automotive applications?
Yes, the HS1DFSH is AEC-Q101 qualified and explicitly listed for automotive applications in its official documentation. It meets stringent reliability requirements including temperature cycling, high-temperature reverse bias, and mechanical shock testing. Its SOD-128 package, halogen-free construction, and J-STD-020 Level 1 moisture sensitivity make it appropriate for automated SMT assembly in automotive ECUs, lighting systems, and battery management modules.
What is the reverse recovery time (trr) of HS1DFSH and how is it measured?
The HS1DFSH has a reverse recovery time (trr) of ≤50 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A at TJ = 25°C. This parameter reflects the time required for the device to transition from forward conduction to reverse blocking state, directly impacting switching losses in high-frequency converters. The HS1DFSH's 50 ns trr supports efficient operation in DC/DC topologies switching above 100 kHz.
Does HS1DFSH have a defined pinout or terminal identification?
Yes, the HS1DFSH uses a two-terminal SOD-128 package with unambiguous polarity: the cathode is marked by a visible band on the device body, and the anode is the opposite end. No internal pin numbering applies - it is a discrete diode with anode and cathode terminals only. Correct orientation is critical for freewheeling and snubber functions; reversed installation will block forward current and cause circuit failure.
What packaging and reel quantity is available for HS1DFSH?
The HS1DFSH is supplied in tape-and-reel packaging with 14,000 units per reel, compatible with standard SMT pick-and-place equipment. The SOD-128 carrier tape meets EIA-481 standards, and the device's matte tin-plated leads comply with J-STD-002 for solderability. This packaging supports high-volume automotive manufacturing and eliminates handling concerns associated with loose components or non-standard reels.
