Product details
Overview
SF2002G from Taiwan Semiconductor is a 20A, 100V super fast recovery rectifier diode in TO-220AB package, featuring 35ns reverse recovery time, 0.975V forward voltage at 10A/25°C, and 150A surge current capability - deployed in DC-DC converters and switching inverters requiring high-efficiency freewheeling.
For engineers reviewing the SF2002G datasheet, SF2002G pinout, SF2002G application, or SF2002G equivalent, key selection criteria include VRRM = 100 V, IF = 20 A, trr = 35 ns, RθJC = 2.5 °C/W, and AEC-Q101 qualification availability (SF2002GH variant), critical for automotive-grade power conversion design.
Technical Context
The SF2002G integrates dual silicon die in a single TO-220AB package with common-cathode configuration, optimized for high-frequency switching applications. Its 35 ns reverse recovery time and low 0.975 V forward voltage at 10 A directly reduce conduction and switching losses in SMPS topologies.
Thermal performance is defined by a junction-to-case resistance of 2.5 °C/W, enabling reliable operation up to 150 °C junction temperature. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements for industrial and automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage; sets upper limit for DC bus or output rail voltage in flyback/freewheeling paths |
| IF | 20 A - continuous average forward current; supports high-power 12–48 V DC-DC stages without forced cooling |
| IFSM | 150 A - non-repetitive surge rating; withstands inrush and fault currents in motor drives and UPS systems |
| trr | 35 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >100 kHz switching without excessive switching loss |
| VF | 0.975 V - forward voltage at IF = 10 A, TJ = 25°C; contributes to <10 W conduction loss per diode in 20 A designs |
| RθJC | 2.5 °C/W - thermal resistance from junction to case; allows direct heatsink mounting with predictable temperature rise under full load |
Pinout & Package
TO-220AB package with 3-terminal configuration: Anode 1, Anode 2, Cathode (common). Matte tin-plated leads comply with J-STD-002 solderability; polarity marked on case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input terminal for first diode | Connects to primary-side switch node or transformer winding in dual-output or interleaved rectification |
| Anode 2 | Input terminal for second diode | Enables independent input routing for dual-channel or phase-split rectification without external isolation |
| Cathode | Common output node | Single low-impedance return path for both diodes; simplifies PCB layout and reduces parasitic inductance in high-dI/dt paths |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery (trr = 35 ns) | Minimizes reverse recovery charge (Qrr) and associated switching loss in hard-switched converters above 50 kHz |
| Low VF (0.975 V @ 10 A) | Reduces conduction loss by ~15% vs. standard fast rectifiers, improving efficiency in 12–24 V output stages |
| Dual-die common-cathode structure | Eliminates need for two discrete TO-220 devices, saving board space and interconnect inductance in dual-input designs |
| AEC-Q101 qualified option (SF2002GH) | Validated for automotive under-hood applications including engine control modules and ADAS power supplies |
Applications

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 | VRRM = 100 V, trr = 35 ns, VF = 0.95 V @ 10 A, TO-220AC package (single-diode) | Single-diode topology requires two devices for dual-anode function; no common-cathode integration | Select when discrete layout control or legacy footprint compatibility is required over integrated dual-anode benefit |
| VS-20EWH06-M3 | VRRM = 60 V, trr = 25 ns, VF = 0.72 V @ 10 A, TO-247AC package | Lower VRRM limits use to ≤48 V systems; superior VF but incompatible voltage rating for 100 V bus designs | Prefer only in low-voltage, ultra-high-efficiency applications where 60 V rating suffices and TO-247 mounting is acceptable |
Compared with STTH2002CT and VS-20EWH06-M3, the SF2002G uniquely delivers 100 V blocking, dual-anode integration, and AEC-Q101 qualification in TO-220AB - making it optimal for space-constrained, automotive-grade dual-input rectification where common-cathode routing and transient robustness are essential.

FAQ
What is the maximum junction temperature rating for the SF2002G?
The SF2002G has a maximum junction temperature (TJ) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version I2104. This rating applies across the full operating range and supports derated continuous conduction up to 20 A when thermal resistance to heatsink is maintained below 2.5 °C/W. The SF2002G must not exceed this limit to ensure long-term reliability and parametric stability.
Does the SF2002G have AEC-Q101 qualification?
The base SF2002G is not AEC-Q101 qualified; however, the SF2002GH variant - identical in electrical and thermal specifications - is fully AEC-Q101 qualified per Version I2104 documentation. The "H" suffix denotes automotive qualification, including stress testing for temperature cycling, humidity bias, and mechanical shock. Designers requiring automotive compliance must specify SF2002GH, not SF2002G.
What is the reverse recovery time (trr) test condition for the SF2002G?
The SF2002G reverse recovery time of 35 ns is measured under the standardized condition: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, as specified in the Electrical Specifications table of the Taiwan Semiconductor SF2001G–SF2008G datasheet (Version I2104). This test method ensures consistent comparison across super fast rectifiers and reflects real-world behavior in hard-switched topologies.
How does the dual-die configuration of the SF2002G affect PCB layout?
With its dual-anode/common-cathode TO-220AB configuration, the SF2002G consolidates two rectifier paths into one footprint - reducing net count, minimizing loop area, and lowering EMI compared to two discrete TO-220 devices. The shared cathode simplifies grounding and eliminates mismatched thermal paths, but requires careful anode trace separation to avoid cross-talk in high-dI/dt applications. Layout must observe minimum creepage between anodes per IPC-2221B.
What is the forward voltage (VF) of the SF2002G at elevated temperature?
The SF2002G forward voltage increases with junction temperature: typical VF rises to ≈1.12 V at IF = 10 A and TJ = 125 °C, based on the Typical Forward Characteristics curve (Fig.4) in the Version I2104 datasheet. This positive temperature coefficient supports current sharing in parallel configurations and must be accounted for in thermal design margining at full-load, high-ambient conditions.
