Product details
Overview
SF2004G from Taiwan Semiconductor is a 200 V, 20 A super fast recovery rectifier diode in TO-220AB package, with 35 ns reverse recovery time and 0.975 V forward voltage at 10 A / 25°C, used for freewheeling and switching-mode power conversion in industrial DC-DC converters.
For engineers reviewing the SF2004G datasheet, SF2004G pinout, SF2004G application, or SF2004G equivalent, key selection criteria include VRRM = 200 V, IF = 20 A, trr = 35 ns, VF = 0.975 V @ 10 A, and TO-220AB thermal resistance RθJC = 2.5 °C/W.
Technical Context
The SF2004G is a single-die, unidirectional super fast rectifier optimized for high-frequency switching applications. Its 35 ns reverse recovery time and low 0.975 V forward voltage at rated current enable reduced switching losses in SMPS topologies operating up to several hundred kHz.
Designed for operation from –55°C to +150°C junction temperature, it features a TO-220AB package with matte tin-plated leads compliant with J-STD-002, and meets JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling circuits |
| IF | 20 A - Continuous average forward current; determines heatsink sizing for steady-state conduction loss |
| trr | 35 ns - Reverse recovery time; enables efficient operation in 100–500 kHz switch-mode converters |
| VF | 0.975 V @ 10 A, 25°C - Forward voltage drop; directly impacts conduction loss and thermal design at nominal load |
| RθJC | 2.5 °C/W - Junction-to-case thermal resistance; enables accurate case temperature estimation under power dissipation |
| IFSM | 150 A - Non-repetitive surge current (8.3 ms); supports inrush and fault-current handling in power supplies |
Pinout & Package
Package: TO-220AB - Insulated case, 3-terminal through-hole package with metal tab (cathode-connected) for mechanical mounting and thermal conduction. Mounting torque ≤ 0.56 N·m.

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 = 200 V, IF = 20 A, trr = 30 ns, VF = 0.95 V @ 10 A, TO-220AC package (isolated tab) | Lower trr and VF, but tab is electrically isolated - simplifies heatsink insulation | Select when lower switching loss and simplified thermal mounting outweigh need for cathode-tab continuity |
| ON Semi MUR2020CT | VRRM = 200 V, IF = 20 A, trr = 35 ns, VF = 1.05 V @ 10 A, TO-220AB package | Higher VF increases conduction loss; identical trr and package pinout | Select when supply chain diversification is prioritized and 80 mV higher VF is acceptable in thermal budget |
Compared with STTH2002CT and MUR2020CT, the SF2004G offers balanced performance with 0.975 V VF and 35 ns trr in a cathode-tab TO-220AB, making it optimal for designs requiring direct cathode-to-heatsink conduction and moderate efficiency targets.

FAQ
What is the maximum junction temperature rating for the SF2004G?
The SF2004G has a maximum junction temperature (TJ) rating of +150°C, with a storage temperature range of –55°C to +150°C. This rating is validated per JEDEC standards and supports operation in demanding industrial environments where ambient temperatures exceed 85°C, provided thermal design maintains TJ ≤ 150°C under worst-case load and airflow conditions. The SF2004G datasheet specifies derating curves confirming usable current down to zero at 150°C case temperature.
Is the SF2004G RoHS and halogen-free compliant?
Yes, the SF2004G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and the matte tin-plated leads are solderable per J-STD-002. These compliance attributes are confirmed in the official Taiwan Semiconductor SF2001G–SF2008G datasheet Version I2104 and apply identically to the SF2004G variant.
Does the SF2004G have AEC-Q101 qualification?
No, the standard SF2004G is not AEC-Q101 qualified. Only the SF2004GH variant (with "H" suffix) carries AEC-Q101 qualification. The SF2004G is intended for industrial and commercial applications; for automotive-grade reliability, engineers must specify SF2004GH and verify qualification documentation directly from Taiwan Semiconductor's automotive product release notes.
What is the reverse recovery time test condition for the SF2004G?
The SF2004G reverse recovery time (trr) of 35 ns is measured under the condition: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, with specified waveform definitions per JEDEC JESD24-10. This test condition reflects typical light-load switching behavior and is representative of performance in high-frequency freewheeling applications. The SF2004G datasheet confirms this value applies across the full operating temperature range.
Can the SF2004G be used in parallel configurations?
The SF2004G is not recommended for direct parallel operation without individual current-sharing resistors or active balancing, due to VF mismatch between units. While its TO-220AB package supports thermal coupling, forward voltage variation (±5% typical) can cause uneven current distribution. For high-current designs, use a single higher-rated device or implement external balancing; the SF2004G datasheet does not specify parallel derating guidelines or matching tolerances.
