Product details
Overview
SF3003PT from Taiwan Semiconductor is a 150 V, 30 A dual-die superfast rectifier in TO-247AD package, configured as a positive-center-tap dual diode for high-efficiency DC/DC conversion. It delivers 35 ns reverse recovery time, 0.95 V forward voltage at 15 A and 25°C, and 1 °C/W junction-to-case thermal resistance for demanding switching applications.
For engineers reviewing the SF3003PT datasheet, SF3003PT pinout, SF3003PT application, or SF3003PT equivalent, key selection factors include its 150 V repetitive peak reverse voltage, center-tap dual-diode topology, low VF at rated current, AEC-Q101 qualification option (SF3003PTH), and thermal performance in high-power SMPS designs.
Technical Context
The SF3003PT integrates two identical silicon die in a single TO-247AD (TO-3P) 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 glass-passivated junctions ensure reliability under thermal cycling and high dv/dt stress.
Designed for high-frequency switching topologies, the device achieves 35 ns trr with 0.25 A reverse recovery current, enabling operation up to several hundred kHz while maintaining low switching losses. The 1 °C/W RθJC supports direct heatsink mounting for sustained 30 A conduction at ≤125°C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar superfast dual-diode rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L06TV1 | 600 V VRRM, 30 A IF, 50 ns trr, TO-247 package, single-diode configuration | Requires external center-tap wiring; higher trr increases switching loss in >300 kHz designs | Select when higher reverse voltage margin is needed and layout allows discrete dual placement |
| IXYS MBR30150CT | 150 V VRRM, 30 A IF, 45 ns trr, TO-247 package, center-tap Schottky | Lower VF (~0.85 V) but limited to 150°C TJ; not suitable for >125°C ambient | Prefer for lower-loss, lower-temp environments where Schottky leakage (<1 mA @ 125°C) is acceptable |
Compared with STTH30L06TV1 and MBR30150CT, the SF3003PT offers optimal balance of 150 V rating, 35 ns recovery, and integrated center-tap topology - reducing PCB area and interconnect inductance while maintaining 150°C operation and AEC-Q101 qualification path.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for SF3003PT?
The SF3003PT has a VRRM of 150 V per diode, as confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version J2103). This rating applies individually to each of the two internal diodes and defines the maximum allowable reverse-biased voltage before breakdown under repetitive conditions.
Is SF3003PT available in an AEC-Q101 qualified version?
Yes, the AEC-Q101 qualified version of SF3003PT is designated SF3003PTH and shares identical electrical and thermal specifications. The "H" suffix indicates qualification to the AEC-Q101 stress test standard for discrete semiconductors, including HTOL, temperature cycling, and ESD testing.
What is the forward voltage (VF) of SF3003PT at rated current?
The SF3003PT exhibits a typical forward voltage of 0.95 V per diode at IF = 15 A and TJ = 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents conduction loss under nominal operating conditions.
How is the pinout configured for the dual-diode structure in SF3003PT?
The SF3003PT uses a positive-center-tap configuration: Anode 1 and Anode 2 are isolated terminals (Leads 1 and 2), while the cathode is the common metal tab. This allows full-wave rectification with a center-tapped AC source or transformer secondary, eliminating the need for four discrete diodes in a bridge.
What thermal resistance does SF3003PT offer between junction and case?
The SF3003PT has a typical junction-to-case thermal resistance (RθJC) of 1 °C/W, as published in the Thermal Performance section of the datasheet. This value assumes proper mounting to a flat, clean heatsink with recommended torque (≤1.13 N·m) and enables accurate thermal modeling for 30 A continuous operation.
