Product details
Overview
SF3001PTH from Taiwan Semiconductor is a 30A, 50V AEC-Q101-qualified superfast dual-center-tap rectifier in TO-247AD package, featuring 35ns reverse recovery time, 0.95V forward voltage at 15A/25°C, and 1°C/W junction-to-case thermal resistance for high-efficiency DC-DC converters.
For engineers reviewing the SF3001PTH datasheet, SF3001PTH pinout, SF3001PTH application, or SF3001PTH equivalent, key selection criteria include repetitive peak reverse voltage (50 V), surge current rating (300 A), junction temperature range (–55°C to +150°C), AEC-Q101 qualification status, and dual-die center-tap configuration for balanced half-wave rectification.
Technical Context
This dual-die superfast rectifier integrates two identical silicon diodes with glass-passivated junctions in a single TO-247AD (TO-3P) package, configured as a positive center-tap arrangement. Its 35 ns trr and low VF enable high-frequency switching operation in hard-switched topologies.
The device supports 30 A average forward current with 300 A non-repetitive surge capability and maintains stable performance across –55°C to +150°C junction temperature range. Thermal resistance of 1°C/W enables efficient heat transfer to heatsinks in power-constrained industrial and automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage per diode; defines minimum input/output isolation margin in 12–24 V DC-DC stages. |
| IF(AV) | 30 A - Continuous average forward current per diode; supports high-power output stages without forced air cooling. |
| trr | 35 ns - Reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables operation up to ~3 MHz switching frequency with minimal switching loss. |
| VF | 0.95 V @ 15 A, 25°C - Low conduction loss per diode; reduces power dissipation by >15% vs. standard fast rectifiers in 24 V systems. |
| RθJC | 1°C/W - Junction-to-case thermal resistance; allows direct mounting to heatsink with predictable temperature rise under full load. |
| IFSM | 300 A - Peak non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients in motor drives and SMPS. |
| TJ Range | –55°C to +150°C - Full operational junction temperature range; qualified for under-hood automotive and industrial ambient conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar superfast dual-center-tap rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L05TV1 | 30 A, 50 V, TO-247, trr = 30 ns, VF = 0.92 V @ 15 A, no AEC-Q101 qualification | Industrial-only use; lacks automotive stress test validation | Select when AEC-Q101 is not required and 5 ns faster trr justifies sourcing from STMicroelectronics. |
| IXYS MBR3050CT | 30 A, 50 V, TO-247, Schottky construction, VF = 0.65 V @ 15 A, trr = N/A, VR = 50 V max | Lower VF but limited to ≤50 V; unsuitable for transient-overvoltage-prone automotive systems | Prefer for low-VF priority in 24 V nominal systems where reverse leakage and temperature stability are secondary concerns. |
Compared with STTH30L05TV1 and MBR3050CT, the SF3001PTH uniquely combines AEC-Q101 qualification, 35 ns trr, and 50 V VRRM in a dual-center-tap TO-247AD package-making it the only option validated for automotive under-hood DC-DC and gate driver supply applications requiring both reliability and timing precision.

FAQ
What does the "H" suffix in SF3001PTH signify?
The "H" suffix in SF3001PTH explicitly denotes AEC-Q101 qualification. This means the SF3001PTH has undergone rigorous stress testing-including temperature cycling, high-temperature reverse bias, and ESD-to meet automotive-grade reliability standards. Unlike the non-H SF3001PT variant, the SF3001PTH is certified for use in automotive powertrain and chassis systems where component failure risk must be minimized.
Is SF3001PTH pin-compatible with other SF30xxPT variants?
Yes, all SF30xxPT and SF30xxPTH devices share identical TO-247AD (TO-3P) packaging and pinout: Anode 1, Cathode (common), and Anode 2. The SF3001PTH uses the same mechanical footprint and terminal layout as SF3002PTH through SF3008PTH, enabling board-level voltage scalability without PCB redesign-only bill-of-materials and transformer turns ratio adjustments are needed.
What is the maximum operating junction temperature for SF3001PTH?
The SF3001PTH has a maximum rated junction temperature (TJ MAX) of +150°C, verified across its full operating range from –55°C to +150°C. This rating is supported by its 1°C/W junction-to-case thermal resistance and glass-passivated chip construction, allowing sustained 30 A conduction in automotive under-hood environments when properly heatsinked.
How does SF3001PTH differ from standard fast recovery diodes in snubber applications?
The SF3001PTH delivers 35 ns reverse recovery time-significantly faster than typical 50–100 ns fast recovery diodes-reducing voltage overshoot and ringing in RCD snubbers. Its low VF (0.95 V) and matched dual-die characteristics also minimize asymmetry-induced losses, making the SF3001PTH especially effective in high-frequency (>200 kHz) snubber networks where timing precision directly impacts MOSFET stress and EMI.
Can SF3001PTH replace Schottky diodes in low-voltage DC-DC outputs?
The SF3001PTH is not a drop-in replacement for Schottky diodes due to higher VF (0.95 V vs. ~0.4–0.65 V) and minority-carrier conduction mechanism. However, in 24 V input systems where reverse leakage and temperature stability are critical-such as automotive gate driver supplies-the SF3001PTH offers superior high-temperature performance and lower IR drift than Schottkys, making it a purpose-fit alternative where reliability outweighs marginal VF advantage.
