Product details
Overview
SF2001PT from Taiwan Semiconductor is a 20A, 50V repetitive peak reverse voltage dual-die super fast rectifier in TO-247AD (TO-3P) package, featuring 35ns reverse recovery time, 0.975V forward voltage at 10A/25°C, and AEC-Q101 qualification option. It serves as a center-tapped dual rectifier in high-efficiency DC-DC converters and snubber circuits.
For engineers reviewing the SF2001PT datasheet, SF2001PT pinout, SF2001PT application, or SF2001PT equivalent, key selection criteria include its 50V VRRM, dual-die configuration with positive center-tap polarity, low RθJC of 2.5°C/W, and verified performance under 180A surge current.
Technical Context
The SF2001PT integrates two independent silicon die in a single TO-247AD package with shared cathode connection and anode pins arranged for center-tapped operation. Its glass-passivated junctions support stable operation from −55°C to +150°C junction temperature, and the 35ns trr enables use in high-frequency switching topologies up to several hundred kHz.
Designed for unidirectional power conversion, the device delivers 20A average forward current with 0.975V VF at 10A/25°C and maintains <10µA reverse leakage at rated 50V VR. Its thermal resistance of 2.5°C/W allows direct heatsink mounting without thermal interface material in many industrial designs.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-die super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2003D | Single-die TO-247, 300V VRRM, 35ns trr, 1.15V VF @10A | Requires external center-tap wiring; no integrated dual-die symmetry | Select when higher voltage rating needed and layout allows discrete implementation. |
| IXYS MUR2050CT | Dual-die TO-247, 50V VRRM, 35ns trr, 1.05V VF @10A, AEC-Q101 qualified | Same VRRM and configuration; slightly higher VF and different thermal profile | Preferred where extended automotive qualification documentation is mandatory. |
Compared with STTH2003D and IXYS MUR2050CT, the SF2001PT offers lower forward voltage and integrated center-tap symmetry in a single package, reducing board area and parasitic imbalance-critical for high-density 48V intermediate bus converters.

FAQ
What is the maximum junction temperature rating for the SF2001PT?
The SF2001PT has a maximum junction temperature (TJ) rating of +150°C, with operational range from −55°C to +150°C. This rating is validated under steady-state conduction and transient surge conditions per the absolute maximum ratings table. Thermal design must ensure that actual junction temperature remains within this limit using the specified RθJC = 2.5°C/W and appropriate heatsinking. The SF2001PT datasheet confirms this value applies across all variants in the SF2001PT–SF2008PT series.
Is the SF2001PT pin-compatible with other parts in the SF200xPT family?
No-the SF2001PT shares the same TO-247AD package and pinout (A1–K–A2) with all SF200xPT variants, but voltage rating differs: SF2001PT is rated for 50V VRRM, while SF2002PT is 100V, etc. Substituting higher-voltage variants does not affect pin compatibility but may increase forward voltage and reduce efficiency at low-voltage operation. The SF2001PT pinout remains identical across the family, enabling shared PCB footprints for design flexibility.
Does the SF2001PT have AEC-Q101 qualification?
The base SF2001PT is not AEC-Q101 qualified; however, the variant SF2001PTH (with "H" suffix) is explicitly AEC-Q101 qualified per the ordering information table. Both share identical electrical and thermal specifications, but only SF2001PTH undergoes the full automotive stress test sequence. For automotive-grade deployment, SF2001PTH must be specified-SF2001PT itself is intended for industrial and commercial applications. The SF2001PT datasheet version I2103 documents this distinction clearly.
What is the reverse recovery time test condition for the SF2001PT?
The SF2001PT reverse recovery time (trr) is measured at IF = 0.5A, IR = 1.0A, and Irr = 0.25A, per the Electrical Specifications table. This standardized condition ensures consistency with JEDEC and industry benchmarks for super fast rectifiers. The measured value is 35ns maximum, confirmed across production lots. This trr directly impacts switching loss and EMI in high-frequency topologies where the SF2001PT is commonly applied.
How does the SF2001PT's forward voltage compare to similar 50V rectifiers?
The SF2001PT delivers 0.975V forward voltage at 10A and 25°C junction temperature-lower than typical alternatives like the MUR2050CT (1.05V) and significantly lower than standard FR30x series (~1.3V). This 60mV advantage reduces conduction loss by 0.6W per diode at 10A, improving thermal margin and overall system efficiency. The SF2001PT achieves this via optimized silicon process and low-resistance metallization, as confirmed in the Electrical Specifications section of its datasheet.
