Product details
Overview
SF2001G from Taiwan Semiconductor is a 20A, 50V 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 freewheeling paths where high switching efficiency and thermal robustness are required.
For engineers reviewing the SF2001G datasheet, SF2001G pinout, SF2001G application, or SF2001G equivalent, key selection criteria include VRRM = 50V, IF = 20A, trr = 35ns, RθJC = 2.5°C/W, and AEC-Q101 qualification availability (SF2001GH variant), all critical for high-frequency power conversion design validation.
Technical Context
The SF2001G employs dual-die construction in a single TO-220AB case, enabling symmetrical thermal distribution and parallel current handling. Its super fast recovery characteristic (trr ≤ 35ns) minimizes switching losses during turn-off in hard-switched topologies.
Designed for operation up to 150°C junction temperature with 2.5°C/W junction-to-case thermal resistance, it supports high-power-density designs when mounted on heatsinks. The device's low 0.975V forward voltage at 10A directly reduces conduction loss in 12V–48V output stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage; defines safe blocking capability in 50V-rated bus applications |
| IF | 20 A - Continuous forward current rating; supports sustained 20A conduction without derating at TC ≤ 80°C |
| IFSM | 150 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and fault transients in SMPS input stages |
| trr | 35 ns - Reverse recovery time; enables efficient operation up to ~500 kHz switching frequency with low EMI |
| VF | 0.975 V @ 10A, 25°C - Low forward drop; reduces conduction loss by ~15% vs. standard fast rectifiers in 12V output rails |
| RθJC | 2.5 °C/W - Junction-to-case thermal resistance; allows 20A operation with ≤50°C case-to-ambient rise using standard TO-220 heatsink |
| Junction Temp | −55°C to +150°C - Wide operating range; supports under-hood automotive and industrial ambient conditions |
Pinout & Package
TO-220AB package with 3-terminal configuration: Anode, Cathode, and Case (electrically connected to Cathode). Mounting tab is cathode-side, requiring insulating hardware if isolated mounting is needed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Lead 1 (Left) | Anode | Main current entry point; connects to switched/high-side node in freewheeling or output rectification |
| Lead 2 (Center) | Cathode | Main current exit point; ties to common rail or ground reference; electrically bonded to metal tab |
| Metal Tab | Cathode (common) | Thermally conductive path to heatsink; must be electrically isolated unless circuit design permits cathode grounding |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery (trr ≤ 35ns) | Enables high-frequency operation (>300 kHz) with minimal switching loss and reduced EMI generation |
| Low VF (0.975 V @ 10A) | Lowers conduction loss by ~1.2W per diode vs. 1.15V alternatives at 10A, improving system efficiency in 12–24V outputs |
| TO-220AB with 2.5°C/W RθJC | Supports 20A continuous current with ≤50°C heatsink temperature rise using standard extruded aluminum heatsinks |
| AEC-Q101 qualified option (SF2001GH) | Validated for automotive powertrain and body electronics applications requiring stress-tested reliability |
| Dual-die construction | Improves current sharing and thermal symmetry versus single-die equivalents, enhancing long-term reliability at full load |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2005D | VRRM = 50V, trr = 35ns, VF = 0.95V @ 10A, TO-220AC package (single leadform) | No cathode-tab connection; requires insulated mounting hardware for heatsink attachment | Preferred where electrical isolation of cathode from heatsink is mandatory |
| VS-20EWH05-M3 | VRRM = 50V, trr = 30ns, VF = 0.92V @ 10A, TO-247AC package with higher thermal mass | Larger footprint and higher cost; better suited for >30A average current or >100°C ambient environments | Selected when extended thermal margin or legacy TO-247 board compatibility is required |
Compared with STTH2005D and VS-20EWH05-M3, the SF2001G offers identical VRRM and trr but integrates cathode-to-tab bonding for simplified heatsinking - making it optimal for space-constrained 20A freewheeling designs where thermal path efficiency outweighs isolation needs.

FAQ
What is the maximum junction temperature rating for the SF2001G?
The SF2001G has a maximum junction temperature (TJ) rating of +150°C, with a minimum storage temperature of −55°C. This wide range supports operation in demanding environments such as under-hood automotive locations or enclosed industrial enclosures where ambient temperatures exceed 85°C. Derating curves in the SF2001G datasheet define allowable forward current versus case temperature.
Is the SF2001G pin-compatible with other members of the SF200xG series?
Yes, all SF200xG devices share identical TO-220AB packaging, pinout, and mechanical dimensions - only VRRM (50V to 600V) and forward voltage (0.975V to 1.700V) differ across the series. The SF2001G can be substituted with SF2002G–SF2008G on the same PCB layout, provided voltage margin and thermal performance are verified for the new rating.
Does the SF2001G meet automotive reliability standards?
The base SF2001G is not AEC-Q101 qualified, but its variant SF2001GH is fully AEC-Q101 certified for automotive power applications. The GH suffix denotes qualification including temperature cycling, humidity testing, and high-temperature reverse bias stress - confirming suitability for engine control units and ADAS power supplies.
What is the reverse recovery time test condition for the SF2001G?
The SF2001G reverse recovery time (trr) is measured at IF = 0.5A, IR = 1.0A, and Irr = 0.25A, per JEDEC standard test methods. This 35ns value reflects performance under realistic commutation conditions in hard-switched converters, not idealized small-signal conditions.
How does the dual-die structure of the SF2001G improve reliability?
The SF2001G uses dual-die construction within one TO-220AB case to balance current distribution and thermal gradients across the silicon area. This reduces localized heating and electromigration risk at full 20A load, extending lifetime in continuous-duty applications like server power supplies compared to single-die rectifiers with equivalent ratings.
