Taiwan Semiconductor Corporation SF2007PT

Overview

SF2007PT from Taiwan Semiconductor is a dual-die, positive-center-tap superfast rectifier in TO-247AD (TO-3P) package, rated for 20A average forward current, 500V repetitive peak reverse voltage (V_RRM), and 35ns reverse recovery time (t_rr). It delivers low forward voltage drop (1.700 V at 10 A, 25°C) and high thermal efficiency with 2.5°C/W junction-to-case thermal resistance, enabling use in high-frequency DC-DC converters and snubber circuits.

For engineers reviewing the SF2007PT datasheet, SF2007PT pinout, SF2007PT application, or SF2007PT equivalent, key selection criteria include its 500V V_RRM, dual-diode center-tap configuration, 180A non-repetitive surge rating, AEC-Q101 qualification availability (SF2007PTH), and compatibility with high-efficiency switching topologies requiring fast recovery and low conduction loss.

Technical Context

The SF2007PT integrates two identical silicon rectifier dies in a single TO-247AD package with shared cathode and isolated anodes-enabling center-tapped transformer secondary rectification without external parallel diodes. Its glass-passivated junctions ensure robustness against humidity and contamination, while the 35ns t_rr supports operation up to several hundred kHz in SMPS designs.

Thermal performance is defined by R_θJC = 2.5°C/W and T_J(max) = 150°C, allowing sustained 20A conduction at case temperatures ≤95°C. Reverse leakage remains ≤10 µA at 25°C and ≤400 µA at 125°C under rated 500V reverse bias, supporting stable operation in high-temperature industrial environments.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for SF2007PT?

The SF2007PT has a V_RRM rating of 500 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version I2103). This value applies per diode in the dual-die structure and defines the highest continuous reverse-bias voltage the device can block without breakdown under normal operating conditions.

Is SF2007PT qualified to AEC-Q101 standards?

The base SF2007PT is not AEC-Q101 qualified; however, the variant SF2007PTH-identical in electrical and thermal specifications-is explicitly listed as AEC-Q101 qualified in the Ordering Information section. The "H" suffix denotes qualification, and both parts share the same TO-247AD package and marking code format.

What is the forward voltage (V_F) of SF2007PT at 20A and 25°C?

Per the Electrical Specifications table, the SF2007PT exhibits a maximum forward voltage of 1.900 V at I_F = 20 A and T_J = 25°C. This value reflects worst-case conduction loss under full-rated current and is critical for calculating power dissipation and thermal design margins.

Does SF2007PT have a center-tap configuration, and how is it implemented?

Yes, the SF2007PT uses a positive-center-tap configuration: two identical rectifier dies share a common cathode (K) terminal while maintaining separate anodes (A1 and A2). This monolithic arrangement eliminates mismatch between discrete diodes and supports true center-tapped transformer rectification without external wiring.

What is the junction-to-case thermal resistance (R_θJC) of SF2007PT, and why does it matter?

The SF2007PT has a typical R_θJC of 2.5°C/W, measured from junction to the metal tab (cathode terminal). This low value enables accurate thermal modeling when the device is mounted to a heatsink, directly impacting safe operating area (SOA) calculations and ensuring reliable 20A operation within industrial temperature ranges.
