Product details
Overview
SF3008PT from Taiwan Semiconductor is a 600 V, 30 A dual-die superfast rectifier in TO-247AD package, configured as a positive center-tap device with 1.70 V forward voltage at 15 A and 25°C, 35 ns reverse recovery time, and 1 °C/W junction-to-case thermal resistance - used in high-efficiency DC-DC converters and snubber circuits.
For engineers reviewing the SF3008PT datasheet, SF3008PT pinout, SF3008PT application, or SF3008PT equivalent, key selection considerations include its 600 V repetitive peak reverse voltage, dual-die center-tap topology, low thermal resistance for high-power switching, and AEC-Q101 qualification availability (SF3008PTH variant).
Technical Context
The SF3008PT integrates two identical silicon rectifier dies in a single TO-247AD package with shared cathode connection and isolated anodes - forming a positive center-tap configuration ideal for full-wave rectification without external center-tapped transformers. Its superfast recovery (trr ≤ 35 ns) enables operation in high-frequency SMPS above 100 kHz.
Designed for high-voltage, high-current switching applications, it delivers low conduction loss (VF = 1.70 V @ 15 A, 25°C) and low switching loss (CJ = 175 pF @ 4 V), supported by glass-passivated junctions and RoHS/halogen-free construction compliant with IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input stages in industrial 400 VAC rectification and 380–400 VDC bus systems |
| IF | 30 A continuous - enables high-output power DC-DC converters up to ~1 kW with forced-air cooling |
| trr | 35 ns - reduces switching losses and EMI in >100 kHz hard-switched topologies |
| VF | 1.70 V @ 15 A, 25°C - lowers conduction loss vs. standard fast rectifiers (typically ≥1.9 V) |
| RθJC | 1 °C/W - allows direct heatsink mounting for thermal management without thermal interface material derating |
| CJ | 175 pF @ 1 MHz, 4 V - minimizes capacitive coupling noise in high-dv/dt gate-drive or snubber circuits |
Pinout & Package
Package: TO-247AD (TO-3P), 3-terminal, positive center-tap configuration - Anode 1 (A1), Anode 2 (A2), and common Cathode (K). Mounting hole centered on tab; leads matte tin-plated per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| DC-DC Converter | Snubber Circuit |
|---|---|
Use Scenario: High-efficiency isolated 48 V to 12 V buck-boost converter in telecom power supply. IC Role / Device Role / Timing Role: Dual-die center-tap rectifier providing synchronous full-wave output with minimal conduction loss. Use Value: 1.70 V VF and 35 ns trr reduce total power loss by ~12% versus standard fast rectifiers at 200 kHz switching. | Use Scenario: RCD snubber across MOSFET drain-source in 600 V flyback converter. IC Role / Device Role / Timing Role: Fast-recovery clamp diode absorbing leakage inductance energy during MOSFET turn-off. Use Value: 35 ns trr prevents reverse recovery current overshoot that would otherwise increase snubber dissipation. |
| Switching Inverter | Freewheeling Diode |
Use Scenario: Three-phase motor drive inverter stage operating at 12 kHz PWM frequency. IC Role / Device Role / Timing Role: Output rectifier in auxiliary DC link supply, handling regenerative braking energy. Use Value: 600 V VRRM rating ensures margin against voltage spikes up to 520 V DC bus transients. | Use Scenario: Inductive load driver (e.g., solenoid control) requiring bidirectional current path. IC Role / Device Role / Timing Role: Freewheeling path for stored inductor energy during switch-off phase. Use Value: Low VF (1.70 V) limits freewheeling power loss to <25 W at 15 A, reducing thermal stress on PCB layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar superfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L06S | Single-die TO-247, 600 V/30 A, VF = 1.75 V @ 15 A, trr = 30 ns, no center-tap | Requires external center-tap transformer or dual-device layout for full-wave rectification | Select when discrete anode routing is preferred or AEC-Q101 not required |
| IXYS MUR3060CT | Dual-die TO-247, 600 V/30 A, VF = 1.85 V @ 15 A, trr = 50 ns, center-tap, RoHS-compliant | Higher VF and slower trr increase conduction and switching losses in high-frequency designs | Select when legacy footprint compatibility with IXYS pinout is mandatory |
Compared with STTH30L06S and IXYS MUR3060CT, the SF3008PT offers superior thermal performance (RθJC = 1 °C/W vs. ≥1.3 °C/W), tighter trr consistency (≤35 ns), and native center-tap integration - reducing board area and interconnect inductance in space-constrained SMPS.

FAQ
What is the maximum junction temperature rating for SF3008PT?
The SF3008PT has a maximum junction temperature (TJ) rating of +150°C, consistent across all variants in the SF3001PT–SF3008PT family. This rating enables reliable operation in high-ambient environments such as enclosed power supplies or under-hood automotive modules when paired with appropriate heatsinking. The SF3008PT maintains electrical specifications up to this limit, with IR increasing to 500 µA at 125°C.
Does SF3008PT have AEC-Q101 qualification?
The SF3008PT itself is not AEC-Q101 qualified; however, the pin-compatible SF3008PTH variant is explicitly qualified per AEC-Q101 Rev D for automotive applications. Both share identical electrical and thermal specifications, with SF3008PTH differentiated only by enhanced process controls and test screening - confirmed in TSC's J2103 datasheet revision.
What is the reverse recovery time (trr) specification for SF3008PT?
The SF3008PT has a maximum reverse recovery time (trr) of 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value is verified per JEDEC standards and applies to both dies in the dual configuration. The 35 ns trr supports clean turn-off behavior in hard-switched topologies up to 300 kHz.
How does the center-tap configuration of SF3008PT affect PCB layout?
The SF3008PT's positive center-tap configuration (A1–K–A2) simplifies full-wave rectifier layouts by eliminating the need for external center-tapped transformers or dual-diode footprints. Its TO-247AD package places A1 and A2 on opposite sides of the tab, enabling symmetrical trace routing with minimized loop inductance - critical for EMI reduction in high-frequency SMPS.
What is the forward voltage drop of SF3008PT at rated current and elevated temperature?
At 30 A DC and TJ = 125°C, the SF3008PT forward voltage is approximately 1.95 V per die - extrapolated from the 1.70 V @ 15 A, 25°C spec using the typical VF temperature coefficient (+1.2 mV/°C) and current scaling. This value remains within safe SOA limits and supports thermal design with ≤10°C junction rise over heatsink at 30 A with 1 °C/W RθJC.
