Product details
Overview
SF3002PT from Taiwan Semiconductor is a dual-die, positive-center-tap superfast rectifier in TO-247AD package, rated for 30 A average forward current, 100 V repetitive peak reverse voltage (VRRM), and 35 ns reverse recovery time (trr). It delivers low forward voltage (0.95 V at 15 A, 25°C) and low thermal resistance (1.0 °C/W junction-to-case), enabling high-efficiency operation in DC–DC converters and switching inverters.
For engineers reviewing the SF3002PT datasheet, SF3002PT pinout, SF3002PT application, or SF3002PT equivalent, key selection criteria include its 100 V VRRM, dual-diode center-tap configuration, TO-247AD mechanical compatibility, AEC-Q101 qualification option (SF3002PTH), and verified 35 ns trr performance under standardized test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A).
Technical Context
The SF3002PT integrates two identical silicon die in a single TO-247AD package with shared cathode connection and isolated anodes-enabling center-tapped full-wave rectification without external wiring. Its glass-passivated junctions ensure stable operation across -55°C to +150°C junction temperature range.
Designed for high-frequency switching applications, the device achieves 35 ns reverse recovery time with low stored charge (Qrr implied by trr and IR test conditions) and exhibits 175 pF junction capacitance per diode at 1 MHz and 4.0 V reverse bias-critical for minimizing switching losses and EMI in SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum non-repetitive reverse blocking voltage per diode; defines usable input voltage headroom in bridge or center-tap topologies |
| IF | 30 A - continuous average forward current at case temperature ≤ 100°C; determines thermal derating requirements in heatsink design |
| trr | 35 ns - measured under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables operation up to ~3 MHz switching frequency before recovery loss dominates |
| VF | 0.95 V - forward voltage per diode at IF = 15 A, TJ = 25°C; directly impacts conduction loss and thermal load in high-current paths |
| RθJC | 1.0 °C/W - junction-to-case thermal resistance; allows precise calculation of junction temperature rise above heatsink temperature |
| IFSM | 300 A - non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current handling in power supplies |
| CJ | 175 pF - junction capacitance per diode at 1 MHz, 4.0 V reverse bias; influences high-frequency turn-off behavior and snubber sizing |
Pinout & Package
Package: TO-247AD (TO-3P), 3-terminal molded plastic case with matte tin-plated leads, UL 94V-0 rated compound, and polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Input terminal for first diode | Connected to AC input leg 1 in center-tap rectifier; requires isolation from heatsink if mounted to common plane |
| Anode 2 (A2) | Input terminal for second diode | Connected to AC input leg 2 in center-tap rectifier; electrically independent from A1 but thermally coupled in shared package |
| Cathode (K) | Common output node | Shared cathode output for full-wave rectified DC; serves as reference point for output filtering and regulation circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die center-tap construction | Enables compact full-wave rectification without external interconnects-reducing parasitic inductance and layout area vs. discrete diode pairs |
| 35 ns reverse recovery time | Minimizes reverse recovery loss and associated EMI in high-frequency switching converters operating above 100 kHz |
| 1.0 °C/W junction-to-case thermal resistance | Supports high-power density designs by enabling efficient heat transfer to external heatsinks with minimal thermal interface resistance |
| 0.95 V forward voltage at 15 A | Reduces conduction loss by ~15% compared to standard fast rectifiers with VF ≥ 1.1 V at same current, improving system efficiency |
| Glass-passivated junctions | Ensures long-term reliability and stable electrical parameters under humid, high-bias, or thermal cycling stress conditions |

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, 35 ns trr, TO-247AC package (single diode) | Higher voltage rating but single-diode; requires external center-tap wiring or dual-device layout | Select when >100 V blocking is required or when discrete layout flexibility outweighs integration benefit |
| IXYS MUR3020CT | 200 V VRRM, 30 A IF, 35 ns trr, TO-247 package, dual common-cathode | Same pinout and thermal profile but higher VRRM; not AEC-Q101 qualified in standard grade | Select for industrial 200 V systems where automotive qualification is unnecessary and higher voltage margin is preferred |
Compared with STTH30L06TV1 and IXYS MUR3020CT, the SF3002PT uniquely combines 100 V rating, dual-center-tap integration, and AEC-Q101 qualification option in one TO-247AD package-offering optimal space, thermal, and compliance efficiency for 12–48 V automotive and industrial DC–DC designs.

FAQ
What is the maximum junction temperature rating for the SF3002PT?
The SF3002PT has a maximum junction temperature (TJ) rating of +150°C, with operational capability down to -55°C. This wide range supports use in under-hood automotive environments and industrial enclosures with elevated ambient temperatures. Thermal design must maintain TJ ≤ 150°C using the specified RθJC = 1.0 °C/W and appropriate heatsinking. The SF3002PT datasheet confirms this limit applies across all operating conditions.
Is the SF3002PT pin-compatible with other parts in the SF300xPT family?
Yes, all SF300xPT devices-including SF3001PT through SF3008PT-share identical TO-247AD package dimensions, pinout (A1, A2, K), and mechanical mounting specifications. Voltage ratings differ only in internal die construction; PCB layout and heatsink interface remain unchanged across the family. The SF3002PT can be substituted for any other SF300xPT variant without hardware modification.
Does the SF3002PT have AEC-Q101 qualification?
The SF3002PT itself is not AEC-Q101 qualified; however, the AEC-Q101-qualified version is designated SF3002PTH (with 'H' suffix). Both share identical electrical and thermal specifications, but SF3002PTH undergoes additional stress testing per AEC-Q101 Rev D. For automotive applications requiring qualification, SF3002PTH-not SF3002PT-must be selected and sourced accordingly.
What is the forward voltage specification for the SF3002PT at elevated temperature?
The SF3002PT forward voltage increases with junction temperature: typical VF is 0.95 V at 25°C and rises to approximately 0.82 V at 125°C (per normalized curve data in the SF300xPT datasheet). This negative temperature coefficient improves current sharing in parallel configurations and reduces thermal runaway risk. The SF3002PT maintains stable VF performance across its full -55°C to +150°C operating range.
How does the SF3002PT's reverse recovery time compare to standard fast rectifiers?
The SF3002PT's 35 ns reverse recovery time (trr) is up to 4× faster than standard fast rectifiers (typically 100–150 ns), measured under identical conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A). This enables higher switching frequencies, lower recovery losses, and reduced EMI generation. The SF3002PT achieves this via optimized carrier lifetime control and low-Qrr design-verified in the official Taiwan Semiconductor characterization report.
