Product details
Overview
SFF2008G from Taiwan Semiconductor is a 20A, 600V super fast rectifier diode in ITO-220AB package, featuring 1.700V forward voltage at 10A/25°C, 35ns reverse recovery time, and 150A surge capability - deployed in high-efficiency DC-DC converters and switching inverters requiring fast switching and low conduction loss.
For engineers reviewing the SFF2008G datasheet, SFF2008G pinout, SFF2008G application, or SFF2008G equivalent, key selection factors include its 600V VRRM, dual-die configuration, AEC-Q101 qualification option (SFF2008GH), junction-to-case thermal resistance of 2.5°C/W, and UL recognition under file #E-326243.
Technical Context
The SFF2008G is a single-phase, dual-die super fast recovery rectifier optimized for high-frequency switching topologies. Its 35ns trr and 1.700V VF at 10A enable reduced switching losses in SMPS and PFC stages, while the ITO-220AB package supports direct heatsink mounting with 0.56 N·m max torque.
Rated for TJ = –55°C to +150°C operation and compliant with JESD201 Class 2 whisker testing, the device delivers stable performance under thermal stress. Its 90pF junction capacitance at 1MHz/4V and 10µA IR at 25°C support low-noise, high-voltage blocking in freewheeling and snubber circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage; defines safe blocking capability in 400–600V bus applications |
| IF | 20 A - continuous forward current rating; supports sustained power delivery without derating below 100°C case temperature |
| IFSM | 150 A - non-repetitive surge current (8.3ms half-sine); handles inrush and fault transients in industrial inverters |
| trr | 35 ns - reverse recovery time; enables efficient operation up to ~500 kHz switching frequency |
| VF | 1.700 V @ 10A, 25°C - forward voltage drop per diode; determines conduction loss and thermal load in high-current paths |
| RθJC | 2.5 °C/W - junction-to-case thermal resistance; allows precise heatsink sizing for 20A continuous operation |
| CJ | 90 pF @ 1 MHz, 4 V - junction capacitance per diode; impacts EMI and switching node ringing in high-dv/dt circuits |
Pinout & Package
Package: ITO-220AB - insulated thermoplastic outline with integral metal tab for direct heatsink mounting; matte tin-plated leads, UL 94V-0 molding compound, polarity marked on body.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2006D | 600V VRRM, 20A IF, 35ns trr, but TO-220AC package (non-insulated tab) | Lacks built-in electrical isolation; requires insulating washer for heatsink mounting | Prefer SFF2008G when system-level isolation or UL-compliant creepage/clearance is required |
| IXYS MUR2060CT | 600V VRRM, 20A IF, dual common-cathode configuration, 60ns trr | Slower recovery increases switching loss above 200 kHz; higher VF (~1.85V) | Choose SFF2008G for higher-frequency designs where trr and VF directly impact efficiency targets |
Compared with STTH2006D and MUR2060CT, the SFF2008G offers integrated insulation, tighter VF tolerance, and superior high-frequency performance - making it optimal for space-constrained, safety-critical, or high-efficiency SMPS where thermal and electrical isolation are design priorities.

FAQ
What is the maximum junction temperature rating for the SFF2008G?
The SFF2008G has a maximum junction temperature (TJ) rating of +150°C, with operational range from –55°C to +150°C. This rating enables reliable use in high-ambient environments such as enclosed industrial enclosures or under-hood automotive power modules. Derating curves in the datasheet define allowable forward current versus case temperature, ensuring thermal safety margins are maintained throughout the SFF2008G's lifetime.
Is the SFF2008G electrically isolated between the tab and leads?
Yes - the SFF2008G uses an ITO-220AB package with an insulated metal tab, meaning the cathode-connected tab is electrically isolated from the mounting surface. This eliminates the need for insulating hardware in most heatsink-mounting configurations. The isolation withstands rated voltage and complies with UL 94V-0 flammability standards, as verified in UL Recognition File #E-326243 for the SFF2008G.
Does the SFF2008G meet AEC-Q101 automotive qualification?
The base SFF2008G is not AEC-Q101 qualified, but the variant SFF2008GH is explicitly qualified per AEC-Q101. The "H" suffix denotes automotive-grade screening including HTOL, temperature cycling, and mechanical shock testing. For automotive applications requiring qualification, specify SFF2008GH - the SFF2008G itself remains suitable for industrial and telecom use where AEC-Q101 is not mandated.
What is the reverse recovery charge (Qrr) specification for the SFF2008G?
The SFF2008G datasheet does not publish Qrr as a standalone parameter; only trr = 35 ns is specified under IF = 0.5A, IR = 1.0A, Irr = 0.25A test conditions. Designers requiring Qrr for loss modeling should derive it from the trr curve and di/dt data in the "Reverse Recovery Time Characteristic" figure (Fig.6), or contact Taiwan Semiconductor for application-specific characterization reports for the SFF2008G.
Can the SFF2008G replace the SFF2007G in an existing design?
Yes - the SFF2008G is a direct voltage-grade upgrade from the SFF2007G (500V → 600V VRRM), with identical IF, IFSM, package, pinout, and thermal characteristics. Forward voltage increases slightly (1.700V vs. 1.550V), but this is offset by the added blocking margin. No PCB or thermal redesign is needed; the SFF2008G maintains full form-fit-function compatibility with the SFF2007G in all systems where 600V rating improves robustness.
