Product details
Overview
SFF2002G from Taiwan Semiconductor is a 20A, 100V super fast rectifier diode in ITO-220AB package with dual-die configuration, 35ns reverse recovery time, 0.975V forward voltage at 10A/25°C, and 150A surge rating - used in DC-DC converters and switching inverters.
For engineers reviewing the SFF2002G datasheet, SFF2002G pinout, SFF2002G application, or SFF2002G equivalent, key selection factors include VRRM=100V, IF=20A, trr=35ns, RθJC=2.5°C/W, and AEC-Q101 qualification availability (SFF2002GH variant).
Technical Context
The SFF2002G integrates two fast-recovery silicon junctions in a single ITO-220AB thermally optimized package, enabling high-efficiency freewheeling and output rectification in high-frequency SMPS topologies. Its 35ns reverse recovery time and low 0.975V forward voltage at 10A directly reduce switching losses and conduction losses.
Designed for operation up to 150°C junction temperature, it supports continuous 20A average forward current with 150A non-repetitive surge capability (8.3ms half-sine), meeting UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage per diode; defines safe operating range in 100V-rated DC-DC outputs |
| IF | 20 A - continuous average forward current; enables high-power rectification without forced air cooling |
| trr | 35 ns - reverse recovery time at IF=0.5A, IR=1.0A, Irr=0.25A; critical for minimizing switching loss in >100kHz converters |
| VF | 0.975 V @ 10A, 25°C - low conduction drop reduces power dissipation and thermal stress in high-current paths |
| RθJC | 2.5 °C/W - junction-to-case thermal resistance; allows direct heatsink mounting for efficient thermal management |
| IFSM | 150 A - peak non-repetitive surge current (8.3ms); withstands startup inrush and transient overloads |
Pinout & Package
Package: ITO-220AB - insulated thermoplastic outline with integral metal tab for direct heatsink mounting; matte tin-plated leads compliant with J-STD-002 solderability; polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input terminal for first diode | Connects to high-side switching node in center-tapped or dual-output configurations |
| Cathode (Tab) | Common cathode for both diodes | Electrically connected to metal tab; must be isolated from chassis unless referenced to system ground |
| Anode 2 (Lead 2) | Input terminal for second diode | Enables dual independent rectification paths or parallel operation with shared cathode |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery | 35ns trr minimizes switching loss in high-frequency (>100kHz) SMPS designs |
| Low forward voltage | 0.975V @ 10A/25°C reduces conduction loss and improves efficiency in 12–48V output stages |
| Dual-die configuration | Two independent anodes sharing one cathode tab enable compact dual-output or interleaved rectification |
| Thermally robust package | ITO-220AB with RθJC=2.5°C/W supports 20A continuous operation with passive heatsinking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2002CT | 20A, 100V dual common-cathode fast diode; trr=35ns, VF=0.95V @ 10A - near-identical electrical specs but TO-220AC package (non-insulated tab) | Requires insulating washer for heatsink mounting; lacks UL recognition and halogen-free certification | Preferred where cost sensitivity outweighs insulation and compliance requirements |
| VS-20EWH06-M3 | 20A, 60V superfast rectifier; trr=30ns, VF=0.87V @ 10A - lower VRRM, faster recovery, lower VF, but not rated for 100V systems | Not suitable for 100V reverse-biased applications; limited to ≤60V output circuits | Select only when system VRRM margin permits 60V rating and lowest possible conduction loss is prioritized |
Compared with STTH2002CT and VS-20EWH06-M3, the SFF2002G uniquely combines 100V VRRM, ITO-220AB insulation, UL recognition, and AEC-Q101 qualification path - making it optimal for safety-critical, thermally constrained, and automotive-adjacent industrial power designs.

FAQ
What is the maximum junction temperature rating for the SFF2002G?
The SFF2002G has a maximum junction temperature (TJMAX) of +150°C, enabling reliable operation in high-ambient industrial environments. This rating is validated under continuous 20A forward current with proper heatsinking and accounts for thermal derating above 25°C ambient. The SFF2002G maintains specified electrical performance within this full temperature range.
Does the SFF2002G have AEC-Q101 qualification?
The base SFF2002G is not AEC-Q101 qualified; however, the SFF2002GH variant - identical in all electrical and mechanical specifications except for extended reliability testing - is AEC-Q101 qualified. Customers requiring automotive-grade validation must specify the 'H' suffix in the ordering code to receive the tested and certified version.
What is the pin configuration of the SFF2002G in the ITO-220AB package?
The SFF2002G uses a three-terminal ITO-220AB package with Anode 1 (lead 1), Cathode (metal tab), and Anode 2 (lead 2). The cathode is internally connected to the insulated metal tab, allowing direct heatsink mounting without electrical shorting. Polarity is marked on the device body per standard industry convention.
How does the SFF2002G compare to standard fast recovery diodes in terms of reverse recovery time?
The SFF2002G achieves a typical reverse recovery time (trr) of 35ns under standardized test conditions (IF=0.5A, IR=1.0A, Irr=0.25A), which is 40–60% faster than conventional fast recovery diodes (typically 60–100ns). This reduction directly lowers switching losses in high-frequency converters operating above 100kHz.
Is the SFF2002G RoHS and halogen-free compliant?
Yes, the SFF2002G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all terminations use matte tin plating compliant with J-STD-002 solderability standards.
