Product details
Overview
HS2JFSH from Taiwan Semiconductor is a 2 A, 600 V high-efficiency surface-mount fast recovery rectifier in SOD-128 package, featuring 75 ns reverse recovery time, 1.10 V forward voltage at 2 A/25°C, and AEC-Q101 qualification for automotive use in DC/DC converters and snubber circuits.
For engineers reviewing the HS2JFSH datasheet, HS2JFSH pinout, HS2JFSH application, or HS2JFSH equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, 60 A surge current rating, 17 °C/W junction-to-lead thermal resistance, and low-profile SOD-128 footprint compatible with automated placement.
Technical Context
The HS2JFSH employs a glass-passivated silicon die optimized for fast switching and low conduction loss in high-frequency power conversion. Its 75 ns trr and 17 pF junction capacitance at 1 MHz/4 V support efficient operation in 100–500 kHz DC/DC topologies.
Designed for automotive-grade reliability, the device meets AEC-Q101 stress test requirements and operates across –55°C to +150°C junction temperature range, with moisture sensitivity level 1 (per J-STD-020) and matte tin-plated leads compliant with J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage; defines usable input voltage range in flyback or boost converters |
| IF | 2 A continuous - rated average forward current at TC = 75°C; supports sustained 2 A load in thermally managed PCB layouts |
| trr | 75 ns - reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables stable switching up to ~500 kHz |
| VF @ 2A/25°C | 1.10 V typical, 1.70 V max - forward voltage drop determines conduction loss and thermal rise in high-duty-cycle operation |
| RθJL | 17 °C/W - junction-to-lead thermal resistance; enables direct heat transfer to copper pad without heatsink for <2 W dissipation |
| CJ @ 1MHz | 17 pF - junction capacitance at VR = 4 V; limits capacitive turn-on loss and EMI in hard-switched applications |
Pinout & Package
Package: SOD-128 - low-profile surface-mount outline with single anode/cathode terminals, 5 mm × 3.7 mm footprint, 1.1 mm max height, and cathode band polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connected to lower-potential side of circuit (e.g., switch node in buck converter); requires adequate copper pour for thermal relief |
| Cathode | Forward current exit / reverse blocking terminal | Connected to higher-potential rail (e.g., output capacitor positive); marked by molded cathode band; carries full load current and reverse leakage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood environments including temperature cycling, HTRB, and ESD per Rev D requirements |
| Glass passivated junction | Provides stable reverse leakage (<1 µA @ 25°C, <80 µA @ 125°C) and long-term reliability against humidity and contamination |
| Low profile SOD-128 | Enables compact power stage layout in space-constrained modules such as OBCs and ADAS ECUs |
| Fast recovery (75 ns) | Reduces switching loss and ringing in high-frequency SMPS, improving efficiency over standard rectifiers by ≥15% at 200 kHz |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to reflow; supports standard J-STD-020-compliant assembly processes |
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 |
|---|---|---|---|
| STTH2R06S | Same 2 A / 600 V rating; trr = 65 ns (slightly faster); VF = 1.15 V @ 2 A; TO-277A package (larger footprint) | Requires PCB layout change due to TO-277A outline; better suited for higher-power derating scenarios | Select when lower trr is critical and board space allows larger package |
| ES2J | Same SOD-128 package; trr = 75 ns; VF = 1.7 V @ 2 A (higher conduction loss); no AEC-Q101 qualification | Limited to non-automotive industrial use; less suitable for thermally constrained automotive modules | Select for cost-sensitive non-automotive designs where AEC-Q101 is not required |
Compared with STTH2R06S and ES2J, the HS2JFSH uniquely combines AEC-Q101 qualification, SOD-128 footprint, and balanced VF/trr performance-making it optimal for space-limited automotive power supplies where reliability and thermal efficiency are jointly prioritized.

FAQ
What is the maximum junction temperature rating for HS2JFSH?
The HS2JFSH has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings table in the official datasheet. This rating enables reliable operation in under-hood automotive environments and high-temperature industrial enclosures. Derating curves confirm 2 A continuous current is sustainable up to 75°C case temperature. The HS2JFSH must be mounted on a minimum 5 mm × 5 mm copper pad to achieve specified thermal resistance.
Does HS2JFSH meet automotive qualification standards?
Yes, the HS2JFSH is explicitly qualified to AEC-Q101 Rev D for stress testing including HTGB, HTRB, temperature cycling, and ESD. This qualification is stated in the Features section of the official datasheet and confirmed in the Mechanical Data and Ordering Information pages. The HS2JFSH is intended for automotive power systems such as DC/DC converters and OBC auxiliary supplies where component-level reliability is mandated.
What is the reverse recovery time (trr) specification for HS2JFSH?
The HS2JFSH has a reverse recovery time (trr) of 75 ns, measured under conditions IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as documented in the Electrical Specifications table. This value applies across the full operating temperature range and is consistent with other members of the HS2JFSH–HS2MFSH series. The HS2JFSH's 75 ns trr supports stable operation in switching power supplies up to 500 kHz.
Is HS2JFSH RoHS and halogen-free compliant?
Yes, the HS2JFSH is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the Features section of the official datasheet. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002. These compliance attributes are integral to the HS2JFSH's qualification for automotive and industrial end equipment requiring strict environmental material declarations.
What package type does HS2JFSH use and what are its key mechanical features?
The HS2JFSH uses the SOD-128 surface-mount package: 5.0 mm × 3.7 mm footprint, 1.1 mm maximum height, cathode band polarity marking, and matte tin-plated leads. Mechanical data confirms it meets JESD 201 Class 2 whisker resistance and J-STD-020 moisture sensitivity level 1-enabling standard reflow without pre-bake. The HS2JFSH's SOD-128 outline is identical across the HS2DFSH–HS2MFSH series.
