Product details
Overview
SF3004PT from Taiwan Semiconductor is a dual-die, center-tapped superfast rectifier in TO-247AD package, rated for 200 V repetitive peak reverse voltage (VRRM), 30 A average forward current (IF), and 35 ns reverse recovery time (trr). It delivers low 0.95 V forward voltage at 15 A and 25°C, enabling high-efficiency operation in DC–DC converters and snubber circuits.
For engineers reviewing the SF3004PT datasheet, SF3004PT pinout, SF3004PT application, or SF3004PT equivalent, key selection factors include its 200 V VRRM, dual-center-tap configuration, 35 ns trr, TO-247AD thermal performance (RθJC = 1°C/W), and AEC-Q101 qualification availability in H-suffix variants.
Technical Context
The SF3004PT integrates two identical superfast rectifier dies in a single TO-247AD package with shared cathode and isolated anodes-enabling center-tapped transformer secondary rectification. Its 35 ns reverse recovery time supports high-frequency switching up to several hundred kHz.
Designed for minimal conduction and switching losses, it combines low 0.95 V forward voltage at 15 A/25°C with low junction-to-case thermal resistance (1°C/W), allowing sustained 30 A operation under forced-air or heatsink-cooled conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum non-repetitive reverse blocking voltage per diode; defines usable input voltage range in flyback or forward converters |
| IF | 30 A - Continuous average forward current per diode; determines power-handling capability in high-current DC–DC outputs |
| trr | 35 ns - Measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables efficient operation in >200 kHz SMPS designs |
| VF | 0.95 V - Forward voltage per diode at IF = 15 A, TJ = 25°C; directly reduces conduction loss and heat generation |
| RθJC | 1°C/W - Junction-to-case thermal resistance; supports thermal design with standard TO-247 heatsinking solutions |
| IFSM | 300 A - Non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients without failure |
Pinout & Package
Package: TO-247AD (TO-3P) - 3-terminal, through-hole, isolated mounting flange; matte tin-plated leads; UL 94V-0 molding compound; polarity marked on case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Input terminal for first rectifier die | Connects to one leg of center-tapped transformer secondary or split-rail source |
| Anode 2 (A2) | Input terminal for second rectifier die | Connects to opposite leg of center-tapped transformer secondary |
| Cathode (K) | Common output node for both dies | Provides single-point DC output connection; enables full-wave center-tap rectification topology |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die center-tap construction | Enables full-wave rectification with single-package footprint and shared thermal path |
| Glass passivated junctions | Ensures long-term reliability and stable electrical parameters under humidity and bias stress |
| Superfast 35 ns recovery | Reduces switching loss and EMI in high-frequency converters (>200 kHz) versus standard fast rectifiers |
| Low 0.95 V forward drop at 15 A | Lowers conduction loss by ~15% vs. comparable 200 V rectifiers with VF ≥ 1.1 V |
| 1°C/W junction-to-case resistance | Allows direct bolt-down heatsinking; supports 30 A continuous operation with ≤ 30°C temperature rise above case |
Applications
| DC–DC Converter Output Stage | Snubber Circuit Clamp Diode |
|---|---|
Use Scenario: Secondary-side synchronous or diode rectification in isolated 48 V–12 V buck-derived DC–DC modules. IC Role / Device Role / Timing Role: Dual-die center-tap rectifier providing full-wave output with minimized conduction loss and thermal coupling. Use Value: 0.95 V VF at 15 A reduces output-stage power loss by >2 W vs. legacy 1.15 V devices, improving efficiency by 0.8–1.2% at full load. | Use Scenario: RCD snubber network across MOSFET drain-source in flyback or forward converters operating at 250 kHz. IC Role / Device Role / Timing Role: Fast-recovery clamp diode absorbing turn-off energy while minimizing reverse recovery ringing. Use Value: 35 ns trr limits snubber ring duration and associated EMI, enabling cleaner switching waveforms than 75 ns alternatives. |
| Switching Inverter Bridge Arm | Freewheeling Path in Inductive Loads |
Use Scenario: Upper/lower arm freewheeling paths in three-phase motor drive inverters with center-tapped DC link. IC Role / Device Role / Timing Role: Dual-anode, common-cathode configuration provides matched, thermally coupled freewheeling paths per phase leg. Use Value: Matched die characteristics ensure balanced current sharing and thermal distribution between arms, reducing hot-spot risk at 30 A continuous. | Use Scenario: Bidirectional freewheeling path in solenoid drivers or relay coil suppression circuits requiring low-loss recirculation. IC Role / Device Role / Timing Role: Low-VF rectifier conducting stored inductive energy during switch-off transitions. Use Value: 0.95 V forward drop minimizes voltage overshoot and dissipation during 30 A freewheeling pulses, extending coil and switch lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar superfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L06TV1 | 600 V VRRM, 30 A IF, 50 ns trr, TO-247AC package, single-die | Higher voltage rating but slower recovery; no center-tap configuration | Select when 600 V blocking is required and center-tap topology is not used |
| IXYS MUR3020CT | 200 V VRRM, 30 A IF, 35 ns trr, TO-247AC, dual center-tap | Identical VRRM, trr, and configuration; slightly higher VF (1.05 V @ 15 A) | Valid alternative where Taiwan Semiconductor supply constraints exist; verify layout compatibility due to minor leadframe variation |
Compared with STTH30L06TV1 and IXYS MUR3020CT, the SF3004PT offers optimal balance of 200 V rating, 35 ns speed, and true dual-die thermal coupling in TO-247AD-making it preferred for thermally demanding center-tap DC–DC and inverter freewheeling where VF and thermal matching are critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for SF3004PT?
The SF3004PT has a VRRM of 200 V, as confirmed in the Absolute Maximum Ratings table across all SF300xPT variants. This value is fixed per part number suffix and defines the highest reverse voltage the device can block repeatedly without breakdown. The SF3004PT is not rated for 300 V or higher-only SF3005PT and above support those voltages.
Does SF3004PT have AEC-Q101 qualification?
The base SF3004PT is not AEC-Q101 qualified; however, the AEC-Q101 variant is designated SF3004PTH (with 'H' suffix). Per the Ordering Information section, 'H' explicitly denotes AEC-Q101 qualification. No qualification data is provided for the standard SF3004PT in the J2103 datasheet revision.
What is the forward voltage (VF) specification for SF3004PT and under what test conditions?
The SF3004PT has a maximum forward voltage of 0.95 V per diode, measured at IF = 15 A and junction temperature TJ = 25°C, using a 0.3 ms pulse width. This value is specified in the Electrical Specifications table and applies only to SF3001PT–SF3004PT variants-not the higher-voltage SF3005PT+ group.
Is SF3004PT a single diode or dual-diode device, and how is it configured?
The SF3004PT contains two independent superfast rectifier dies in a single TO-247AD package, arranged in a positive center-tap configuration: Anode 1 and Anode 2 are electrically isolated inputs, while the Cathode is the common output node. This allows full-wave rectification from a center-tapped transformer or split-rail source without external interconnection.
What is the thermal resistance (RθJC) of SF3004PT and how does it impact heatsink design?
The SF3004PT has a typical junction-to-case thermal resistance (RθJC) of 1°C/W, as stated in the Thermal Performance section. This means that for every watt of power dissipated, the junction temperature rises 1°C above the case temperature-enabling precise thermal modeling. With 30 A conduction at 0.95 V, ~28.5 W loss requires a heatsink capable of maintaining case temperature ≤ 120°C to keep TJ ≤ 150°C.
