Product details
Overview
SFF2007G from Taiwan Semiconductor is a 20A, 600V super fast rectifier diode in ITO-220AB package with dual-die configuration, VF = 1.700 V at IF = 10 A and TJ = 25°C, trr = 35 ns, and RθJC = 2.5°C/W - used in high-frequency DC/DC converters requiring low recovery loss and thermal robustness.
For engineers reviewing the SFF2007G datasheet, SFF2007G pinout, SFF2007G application, or SFF2007G equivalent, key selection criteria include peak reverse voltage (600 V), forward surge capability (150 A), junction temperature range (–55°C to +150°C), AEC-Q101 qualification status, and ITO-220AB mechanical mounting requirements.
Technical Context
The SFF2007G implements a super fast recovery silicon PN junction optimized for switching-mode power supplies operating above 20 kHz. Its 35 ns reverse recovery time and 90 pF junction capacitance per die support minimal switching loss during turn-off transitions.
Thermally, the device uses a copper leadframe within an ITO-220AB molded case rated UL 94V-0, delivering 2.5°C/W junction-to-case resistance and enabling 20 A continuous conduction with appropriate heatsinking at ≤100°C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage; defines usable input voltage headroom in boost/flyback topologies |
| IF | 20 A - average forward current rating at TC = 100°C; determines continuous power handling with thermal management |
| IFSM | 150 A - non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current tolerance |
| VF | 1.700 V @ IF = 10 A, TJ = 25°C - forward voltage drop directly impacts conduction loss and thermal design |
| trr | 35 ns - reverse recovery time; limits minimum switching frequency and reduces switching loss in hard-switched converters |
| RθJC | 2.5°C/W - junction-to-case thermal resistance; enables accurate heatsink sizing for target TJ ≤ 150°C |
Pinout & Package
Package: ITO-220AB - insulated thermoplastic outline with integral metal tab, matte tin-plated leads, UL 94V-0 molding compound, 1.82 g mass, and 0.56 N·m max mounting torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to input/high-side node in freewheeling or output rectification paths |
| Cathode (Lead 2) | Forward current exit point | Connected to ground/common return or output filter capacitor negative terminal |
| Tab (Case) | Electrically connected to cathode | Provides thermal path to heatsink; must be electrically isolated unless circuit design permits cathode tie |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery (trr ≤ 35 ns) | Enables efficient operation in 50–500 kHz SMPS without excessive switching loss or EMI |

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 | 600 V VRRM, 20 A IF, VF = 1.75 V @ 10 A, trr = 30 ns, TO-220AC package (cathode-isolated tab) | Lower trr but higher VF; tab not internally tied to cathode - enables floating heatsink mounting | Select when electrical isolation between heatsink and cathode is required; verify layout compatibility with different pinout |
| IXYS MUR2060CT | 600 V VRRM, 20 A IF per diode, VF = 1.85 V @ 10 A, trr = 50 ns, TO-220AB package (cathode-tied tab) | Higher VF and slower trr; dual common-cathode configuration differs from SFF2007G's dual-die independent structure | Acceptable where slightly higher conduction loss is tolerable; confirm dual-die functional equivalence for paralleling use cases |
Compared with STTH2006D and IXYS MUR2060CT, the SFF2007G offers balanced VF/trr trade-off and integrated cathode-tied tab in ITO-220AB - simplifying heatsink design while maintaining 600 V/20 A capability for cost-sensitive industrial and automotive power stages.

FAQ
What is the maximum junction temperature rating for the SFF2007G?
The SFF2007G has a maximum junction temperature (TJ MAX) of +150°C, with operational range from –55°C to +150°C. This rating enables reliable operation in high-ambient environments such as automotive engine compartments or enclosed industrial power supplies when paired with appropriate heatsinking based on its 2.5°C/W RθJC value.
Is the SFF2007G AEC-Q101 qualified?
The base SFF2007G is not AEC-Q101 qualified; however, the variant SFF2007GH is explicitly qualified per AEC-Q101. The "H" suffix denotes automotive-grade screening and testing - critical for use in ADAS, body control modules, and on-board chargers where reliability under thermal cycling and mechanical stress is mandatory.
What does the marking code 'SFF2007G' indicate on the device body?
The marking code 'SFF2007G' identifies the specific device family (SFF), current rating (20 A), voltage grade (600 V, encoded as '07'), and green halogen-free compound ('G'). It matches the ordering code SFF2007G and confirms ITO-220AB packaging per TSC's standardized marking diagram.
How does the dual-die configuration of the SFF2007G affect circuit layout?
The SFF2007G integrates two independent rectifier dies in one ITO-220AB package, electrically isolated from each other. This allows flexible use as two separate 20 A/600 V devices or paralleled for higher current - but requires careful PCB routing to avoid shared parasitic inductance that could unbalance current sharing between dies.
What is the reverse recovery time (trr) test condition for the SFF2007G?
The SFF2007G reverse recovery time is specified as 35 ns maximum under conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, measured using the test circuit in Figure 6 of the datasheet. This reflects real-world behavior in hard-switched converters where diode commutation occurs rapidly across the zero-crossing point.
