Product details
Overview
S2JFSH from Taiwan Semiconductor is a 2 A, 600 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 S2JFSH datasheet, S2JFSH pinout, S2JFSH application, or S2JFSH equivalent, key selection criteria include repetitive peak reverse voltage (600 V), forward voltage at 2 A (0.98 V max @ 25°C), thermal resistance (RθJL = 14 °C/W), junction temperature range (–55 to +150 °C), and moisture sensitivity level (MSL 1).
Technical Context
The S2JFSH is a single-die, unidirectional standard recovery rectifier optimized for high-reliability automotive and industrial power conversion. 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 mount: RθJA = 74 °C/W, RθJC = 20 °C/W, enabling sustained 2 A average forward current up to 125°C ambient when properly heatsinked via lead termination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or clamp circuits |
| IF | 2 A - Continuous average forward current rating at TA = 75°C on standard PCB; derates linearly above that temperature |
| IFSM | 50 A - Non-repetitive surge current (8.3 ms half-sine); supports transient energy absorption in snubber networks |
| VF @ 2 A, 25°C | 0.98 V max - Forward conduction loss directly impacts efficiency and thermal rise in high-duty-cycle rectification |
| RθJL | 14 °C/W - Junction-to-lead thermal resistance; enables direct thermal path to PCB copper for passive cooling |
| TJ Range | –55 to +150 °C - Full automotive-grade operating junction temperature range; validated per AEC-Q101 stress tests |
| CJ | 12 pF @ 1 MHz, 4 V - Junction capacitance affects high-frequency switching noise and EMI in fast-switching topologies |
Pinout & Package
Package: SOD-128 - Low-profile, surface-mount molded package with matte tin-plated leads, UL 94V-0 rated compound, cathode band polarity marking, and MSL 1 handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of load or switch node; requires adequate copper area for thermal dissipation |
| Cathode | Forward current exit / reverse blocking terminal | Marked by visible band; ties to higher-potential rail or output node; critical for correct orientation in automated placement |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood applications including temperature cycling, HTRB, and UHAST |
| Glass-passivated junction | Eliminates risk of junction corrosion and leakage drift in humid or chemically aggressive environments |
| MSL 1 rating | Zero bake requirement before reflow; compatible with standard SMT assembly without moisture preconditioning |
| Low-profile SOD-128 | Height ≤ 1.1 mm enables use in space-constrained modules such as engine control units and ADAS power supplies |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally regulated end equipment |
Applications
| Automotive DC/DC Converters | Industrial Snubber Circuits |
|---|---|
Use Scenario: Step-down conversion in 12 V/48 V dual-battery systems for ADAS camera modules and radar ECUs. IC Role / Device Role / Timing Role: Output rectifier in synchronous or asynchronous buck-derived topologies, conducting during low-side switch off-time. Use Value: 600 V VRRM provides margin against load-dump transients; 50 A IFSM absorbs switch-node ringing energy without failure. | Use Scenario: RC snubber across IGBTs or MOSFETs in motor drives and UPS inverters to suppress dv/dt-induced false triggering. IC Role / Device Role / Timing Role: Freewheeling path for snubber capacitor discharge; clamps voltage spikes during turn-off transitions. Use Value: Low VF (0.98 V max) minimizes conduction loss during repeated snubbing pulses; glass passivation ensures long-term reliability under thermal cycling. |
| Automotive Freewheeling Diodes | On-Board Charger Input Rectification |
Use Scenario: Freewheeling path in solenoid drivers, fuel injector controls, and HVAC blower motor regulators. IC Role / Device Role / Timing Role: Provides continuous current path when inductive load is de-energized; conducts only during flyback phase. Use Value: –55 to +150 °C TJ range supports operation near hot engine compartments; MSL 1 simplifies manufacturing logistics. | Use Scenario: Input bridge rectification stage in bi-directional OBCs converting AC grid to DC link for battery charging. IC Role / Device Role / Timing Role: One leg of full-wave bridge; handles 2 A average input current at line frequency with minimal heating. Use Value: RθJL = 14 °C/W allows direct thermal coupling to PCB ground plane; 12 pF CJ limits capacitive coupling noise into sensitive control circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06S | Same 2 A / 600 V rating; TO-277 package (higher RθJA = 90 °C/W); VF = 1.15 V max @ 2 A | Requires larger PCB footprint and additional thermal vias; less suitable for ultra-thin modules | Prefer S2JFSH where board height < 1.2 mm or MSL 1 compliance is mandatory |
| ES2J | Same SOD-128 package; 2 A / 600 V; VF = 1.05 V max @ 2 A; not AEC-Q101 qualified | Lacks automotive stress validation; limited to industrial/commercial temperature range (–40 to +125 °C) | Choose S2JFSH for automotive OEM designs requiring AEC-Q101 traceability and extended TJ |
Compared with STTH2R06S and ES2J, the S2JFSH uniquely combines AEC-Q101 qualification, MSL 1 handling, and low-profile SOD-128 packaging-making it the only option among the three qualified for under-hood automotive deployment without layout or thermal redesign.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the S2JFSH?
The S2JFSH has a VRRM of 600 V, meaning it can reliably block up to 600 V of reverse voltage in repetitive operation without breakdown. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version B2103) and applies across the full operating temperature range.
Is the S2JFSH suitable for automotive applications?
Yes, the S2JFSH is AEC-Q101 qualified and explicitly listed for automotive applications in its official documentation. It meets stress test requirements including temperature cycling, high-temperature reverse bias (HTRB), and unbiased highly accelerated stress testing (UHAST), making it suitable for under-hood and body-control module deployments.
What package type does the S2JFSH use, and what are its key mechanical features?
The S2JFSH uses the SOD-128 surface-mount package: low-profile (≤1.1 mm height), UL 94V-0 rated molding compound, matte tin-plated leads compliant with J-STD-002, and cathode polarity indicated by a visible band. Its MSL level is 1, eliminating pre-bake requirements prior to reflow soldering.
What is the forward voltage (VF) of the S2JFSH at 2 A and 25°C?
The S2JFSH exhibits a maximum forward voltage of 0.98 V at 2 A and 25°C, as specified in the Electrical Specifications table. At elevated junction temperatures (125°C), VF drops to 0.88 V typical and 0.98 V maximum, reflecting the negative temperature coefficient of silicon PN junctions.
Does the S2JFSH have halogen-free and RoHS compliance certifications?
Yes, the S2JFSH is both RoHS compliant per EU Directive 2011/65/EU and halogen-free in accordance with IEC 61249-2-21. These environmental qualifications are explicitly stated in the Features section of the official Taiwan Semiconductor datasheet (Version B2103) and verified through material declarations.
