Product details
Overview
SFF2002GHC0G from Taiwan Semiconductor is a 20A, 100V super fast rectifier diode in ITO-220AB package with dual-die configuration, 150A surge rating, 2.5°C/W junction-to-case thermal resistance, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or output rectifier in high-frequency switching power supplies.
For engineers reviewing the SFF2002GHC0G datasheet, SFF2002GHC0G pinout, SFF2002GHC0G application, or SFF2002GHC0G equivalent, key selection factors include its 100V VRRM, 0.975V typical forward voltage at 10A/25°C, 35ns reverse recovery time, dual-die thermal performance, and AEC-Q101 compliance for under-hood automotive use.
Technical Context
This device implements a dual-die super fast recovery rectifier structure optimized for high-efficiency DC-DC conversion. Its 35ns trr and low VF enable reduced switching losses in 100–500kHz SMPS topologies, while the ITO-220AB package supports direct heatsink mounting with 0.56 N·m torque limit.
The AEC-Q101 qualification confirms robustness against temperature cycling, mechanical shock, and humidity exposure per automotive stress test standards. Dual-die layout improves current sharing and thermal distribution versus single-die alternatives at 20A continuous conduction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2002D | Same ITO-220AB package, 20A/100V, but 50ns trr and no AEC-Q101 qualification | Not suitable for automotive; acceptable for industrial/commercial SMPS where surge immunity is primary concern | Select STTH2002D only if AEC-Q101 is not required and higher trr is acceptable in design margin |
| VS-20EWH06-M3 | 20A/60V, 30ns trr, TO-247AC package, AEC-Q101 qualified | Limited to ≤60V systems; requires larger PCB footprint and different mounting hardware than ITO-220AB | Choose VS-20EWH06-M3 only for 60V-rated designs needing faster recovery and same automotive qualification |
Compared with STTH2002D and VS-20EWH06-M3, the SFF2002GHC0G uniquely combines 100V VRRM, AEC-Q101 qualification, and 35ns trr in the space-constrained ITO-220AB form factor-making it optimal for automotive 48V systems and industrial 100V-clamp applications requiring both voltage headroom and fast switching.

FAQ
What is the maximum junction temperature rating for the SFF2002GHC0G?
The SFF2002GHC0G has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This rating enables operation in high-ambient environments such as engine compartments or sealed industrial enclosures. Derating curves confirm 20A continuous current is sustainable up to 85°C case temperature. The SFF2002GHC0G must be thermally managed using the ITO-220AB tab with appropriate heatsinking to maintain TJ ≤150°C under full load.
Does the SFF2002GHC0G have AEC-Q101 qualification, and what does the 'H' suffix indicate?
Yes, the SFF2002GHC0G is AEC-Q101 qualified-the 'H' in the part number explicitly denotes this automotive-grade reliability certification per ordering information table. The 'C0G' suffix indicates green (halogen-free) compound and standard date code format. AEC-Q101 validation covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. The SFF2002GHC0G is approved for use in non-safety-critical automotive power systems such as body control modules and ADAS auxiliary supplies.
What is the reverse recovery time (trr) specification for the SFF2002GHC0G, and under what test conditions is it measured?
The SFF2002GHC0G has a maximum reverse recovery time (trr) of 35 ns, measured under the conditions: forward current IF = 0.5 A, reverse current IR = 1.0 A, and reverse recovery current Irr = 0.25 A, per the Electrical Specifications table. This value is confirmed across the full temperature range and reflects the device's super fast recovery capability. The SFF2002GHC0G achieves this performance via optimized lifetime control in the epitaxial layer, making it suitable for high-frequency switching topologies where diode switching loss dominates efficiency.
How does the dual-die configuration of the SFF2002GHC0G impact thermal and electrical performance?
The dual-die configuration in the SFF2002GHC0G provides two independent 10A-rated diode elements in one ITO-220AB package, enabling current sharing and distributed heat generation. This lowers effective thermal resistance versus a single 20A die and improves reliability under transient overloads. Electrically, it allows flexible circuit routing-such as interleaved rectification or redundant outputs. The SFF2002GHC0G leverages this architecture to achieve 2.5°C/W RθJC while maintaining isolation between anode terminals, unlike monolithic dual-diode packages with shared cathodes.
Is the SFF2002GHC0G pin-compatible with other devices in the SFF200xG series, and how do forward voltage characteristics vary across the series?
Yes, all SFF200xG and SFF200xGH devices-including SFF2002GHC0G-share identical ITO-220AB package, pinout, and mechanical dimensions. Forward voltage varies by voltage rating: SFF2001G–SFF2004G (50–200V) specify 0.975V typical VF; SFF2005G–SFF2006G (300–400V) specify 1.300V; SFF2007G–SFF2008G (500–600V) specify 1.700V. Thus, the SFF2002GHC0G delivers the lowest VF among 100V+ variants in the family, optimizing efficiency in mid-voltage applications.
