Product details
Overview
SFAS1008GH from Taiwan Semiconductor is a 10A, 600V super fast surface-mount rectifier in TO-263AB (D2PAK) package, featuring 35ns reverse recovery time, 1.7V max forward voltage at 10A, and AEC-Q101 qualification for automotive-grade reliability - used in DC-DC converters and freewheeling paths in engine control units.
For engineers reviewing the SFAS1008GH datasheet, SFAS1008GH pinout, SFAS1008GH application, or SFAS1008GH equivalent, key selection criteria include surge capability (125A IFSM), thermal resistance (2.2°C/W RθJC), junction temperature range (–55°C to +150°C), and halogen-free, RoHS-compliant construction per J-STD-020 Level 1 moisture sensitivity.
Technical Context
The SFAS1008GH employs a single-die, glass-passivated silicon junction optimized for high-speed switching in unidirectional power conversion. Its 35ns trr and low 1.7V VF at rated current enable efficient operation in high-frequency DC-DC topologies where conduction and switching losses must be minimized.
Designed for automotive environments, it meets AEC-Q101 stress testing requirements and supports continuous operation up to +150°C junction temperature. The TO-263AB package provides robust thermal dissipation (RθJC = 2.2°C/W) and matte tin-plated leads compliant with J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - blocks up to 600V reverse voltage without breakdown, suitable for 400V DC bus applications with safety margin |
| IF | 10 A - continuous forward current rating at case temperature ≤ 110°C, defines steady-state power handling |
| IFSM | 125 A - non-repetitive surge current capacity (8.3ms half-sine), supports motor startup and transient load events |
| trr | 35 ns - reverse recovery time under IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables >1 MHz switching in snubberless designs |
| RθJC | 2.2 °C/W - junction-to-case thermal resistance; allows ~45W power dissipation with 100°C ΔT to heatsink |
| VF (max) | 1.7 V @ 10A, 25°C - sets conduction loss floor; contributes ~17W worst-case dissipation at full load |
| TJ Range | –55°C to +150°C - qualified operating range for under-hood automotive electronics and industrial power supplies |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal configuration with exposed cathode tab for thermal and electrical connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry point | Connected to source-side of switching node; requires PCB copper pour for thermal relief |
| Cathode (Tab) | Output current exit / heat sink interface | Exposed metal tab serves as both cathode terminal and primary thermal path to heatsink or PCB plane |
| NC / Dummy Lead (Lead 2) | Mechanical support only | Non-functional lead; present for mechanical stability and alignment during automated placement |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD tests - eliminates requalification for Tier-1 power modules |
| Glass passivated junction | Enhances long-term reliability under humidity and bias stress; prevents surface leakage degradation in harsh environments |
| Moisture sensitivity Level 1 | No bake requirement before SMT reflow; compatible with standard J-STD-020 assembly processes without dry-pack handling |
| Halogen-free & RoHS | Meets IEC 61249-2-21 and EU RoHS directives - supports green manufacturing and end-of-life compliance |
| Low VF & fast trr synergy | Simultaneous reduction of conduction loss (VF) and switching loss (trr) improves overall efficiency in 200–500 kHz DC-DC converters |
Applications
| DC-DC Converter | Automotive Lighting |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated 48V-to-12V buck-boost converters for ADAS domain controllers. IC Role / Device Role / Timing Role: Unidirectional power switch providing low-loss freewheeling path during high-side MOSFET off-time. Use Value: 35ns trr minimizes reverse recovery charge loss; 1.7V VF reduces conduction loss by ~12% vs. standard fast rectifiers at 10A. | Use Scenario: LED driver output stage in adaptive front lighting systems (AFS), handling PWM dimming transients. IC Role / Device Role / Timing Role: Freewheeling diode across inductive LED current regulator to clamp flyback voltage spikes. Use Value: 125A IFSM withstands inrush during cold-start; AEC-Q101 ensures operation at –40°C to +125°C ambient. |
| Snubber Network | Engine Control Unit (ECU) |
Use Scenario: RC snubber across IGBTs in 12V starter-generator inverters to suppress voltage overshoot during turn-off. IC Role / Device Role / Timing Role: Fast-recovery clamping diode that resets snubber capacitor with minimal stored charge. Use Value: Low Qrr (derived from 35ns trr and CJ = 60pF) reduces snubber energy dissipation and thermal stress. | Use Scenario: Reverse polarity protection and load dump suppression in 5V/3.3V auxiliary power rails of gasoline/diesel ECUs. IC Role / Device Role / Timing Role: Primary input rectifier and transient clamp in offline AC-DC or battery-input DC-DC stages. Use Value: 600V VRRM accommodates 300V peak transients per ISO 7637-2; TJ max = +150°C matches under-hood thermal envelope. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R06DJF | 600V, 10A, trr = 30ns, VF = 1.75V, TO-263AB, AEC-Q101 qualified | Marginally faster trr but higher VF; identical package and surge rating | Preferred where <30ns trr is critical and 50mV VF penalty is acceptable |
| VS-10EWH06-M3 | 600V, 10A, trr = 40ns, VF = 1.65V, TO-263AB, AEC-Q101 qualified | Lower VF but slower recovery; same thermal performance and moisture level | Better for thermally constrained layouts where conduction loss dominates |
Compared with STTH10R06DJF and VS-10EWH06-M3, the SFAS1008GH delivers balanced trade-off: 35ns trr enables medium-frequency switching while maintaining 1.7V VF ceiling and proven AEC-Q101 field reliability in automotive power stages.
