Product details
Overview
SF3001PT from Taiwan Semiconductor is a 30A, 50V repetitive peak reverse voltage super fast rectifier in TO-247AD package, featuring dual-die center-tapped construction, 35ns reverse recovery time, 0.95V forward voltage at 15A/25°C, and AEC-Q101 qualification option. It serves as a high-efficiency freewheeling or snubber diode in DC-DC converters operating under high-frequency switching.
For engineers reviewing the SF3001PT datasheet, SF3001PT pinout, SF3001PT application, or SF3001PT equivalent, key selection criteria include its 50V VRRM, 30A continuous forward current rating, low RθJC of 1°C/W, dual-center-tap configuration, and suitability for automotive-grade power conversion where thermal performance and fast recovery are critical.
Technical Context
The SF3001PT integrates two identical silicon rectifier dies in a single TO-247AD (TO-3P) package with shared cathode and isolated anodes-enabling center-tapped transformer secondary rectification without external parallel devices. Its glass-passivated junction ensures reliability under thermal cycling and humidity stress.
Designed for high-frequency switching topologies, the device delivers 35ns reverse recovery time at IF = 0.5A / IR = 1.0A / Irr = 0.25A, with 175pF junction capacitance per diode at 1MHz/4V, supporting efficient operation in 100kHz–500kHz SMPS designs while maintaining low conduction loss via 0.95V VF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum non-repetitive reverse blocking voltage; defines minimum input/output isolation margin in 24V–48V DC-DC systems |
| IF | 30 A - Continuous average forward current at case temperature ≤ 100°C; supports 300W+ output in compact heatsinked designs |
| trr | 35 ns - Measured under standardized 0.5A/1.0A/0.25A conditions; enables <500kHz switching without excessive switching loss |
| VF | 0.95 V @ 15A, 25°C - Low conduction drop reduces power dissipation by ~1.4W vs. 1.2V alternatives at same load |
| RθJC | 1 °C/W - Junction-to-case thermal resistance; allows direct mounting to heatsink with minimal thermal interface resistance |
| IFSM | 300 A - Non-repetitive surge rating (8.3ms half-sine); withstands inrush and fault currents in industrial motor drives |
| CJ | 175 pF @ 1MHz, 4V - Per-diode junction capacitance; limits high-frequency displacement current in snubber networks |
Pinout & Package

IC Role / Device Role / Timing Role: High-reliability rectifier converting transformer output to DC bus feeding LED string controller ICs. Use Value: Glass-passivated junction ensures <1µA IR drift after 1000hr HTOL testing at 125°C, preventing output droop in sealed luminaires. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar superfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L06D | 600V VRRM, 30A IF, 50ns trr, TO-247 package, single diode | Higher voltage rating but slower recovery; unsuitable for <200kHz designs requiring <40ns trr | Select only if system requires >500V blocking and can tolerate higher switching loss |
| IXYS MBR30H50CT | 50V VRRM, 30A IF, Schottky construction, 2-pin TO-247, no center tap | No center-tap capability; requires external dual-diode layout for same topology | Choose when lowest VF (<0.55V) is prioritized over topology integration and reverse leakage tolerance |

FAQ
What is the maximum junction temperature rating for SF3001PT?
The SF3001PT has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the J2103 datasheet. This allows operation in high-ambient environments such as enclosed power supplies or under-hood automotive locations when mounted to an adequately sized heatsink. The SF3001PT maintains specified electrical parameters up to this limit, provided case temperature does not exceed 100°C at 30A DC load.
Does SF3001PT have AEC-Q101 qualification?
The SF3001PT itself is not automatically AEC-Q101 qualified; however, the SF3001PTH variant-identical in all electrical and mechanical specifications except for qualification status-is explicitly AEC-Q101 certified per the ordering information table. Engineers requiring automotive-grade validation must specify SF3001PTH; the SF3001PT remains suitable for industrial and commercial applications where qualification is not mandated.
What is the forward voltage specification for SF3001PT at elevated temperature?
The SF3001PT forward voltage is specified as 0.95V maximum at IF = 15A and TJ = 25°C. While no explicit high-temperature VF value is given in the datasheet, typical curves (Fig.4) show VF increases to approximately 0.82V at 15A and 125°C junction temperature. This positive temperature coefficient aids current sharing in parallel configurations and improves thermal stability in high-power designs using SF3001PT.
Can SF3001PT replace SF3002PT in a 100V-rated circuit?
No-SF3001PT is rated for 50V VRRM and must not be substituted for SF3002PT (100V VRRM) in circuits where reverse voltage exceeds 50V. Exceeding VRRM risks avalanche breakdown and catastrophic failure. The SF3001PT marking code "3001" directly correlates to its 50V rating per the absolute maximum ratings table; using it in a 100V application violates safe operating area constraints defined in the J2103 datasheet.
What is the meaning of the "PT" suffix in SF3001PT?
The "PT" suffix in SF3001PT denotes the TO-247AD (TO-3P) package variant per TSC's ordering code convention. It distinguishes this leaded, through-hole molded package from other form factors such as surface-mount or stud-mount versions. The "PT" does not indicate plating type, qualification level, or thermal enhancement-it solely identifies the mechanical outline and termination style used for SF3001PT.
