Product details

Overview

SF2006PT from Taiwan Semiconductor is a 20A, 400V repetitive peak reverse voltage (V_RRM) superfast dual rectifier in TO-247AD package, featuring 1.300 V forward voltage at 10 A and 25°C, 35 ns reverse recovery time, and AEC-Q101 qualification option. It serves as a center-tap dual-die rectifier in high-efficiency DC-DC converters and snubber circuits.

For engineers reviewing the SF2006PT datasheet, SF2006PT pinout, SF2006PT application, or SF2006PT equivalent, key selection criteria include its 400V V_RRM, dual-die center-tap configuration, 2.5°C/W junction-to-case thermal resistance, and compatibility with high-frequency switching topologies requiring low trr and low conduction loss.

Technical Context

The SF2006PT integrates two independent silicon die in a single TO-247AD package with positive center-tap configuration - enabling full-wave rectification without external center-tapped transformers. Its glass-passivated junctions support stable operation up to 150°C junction temperature and meet JESD201 Class 2 whisker resistance.

Designed for high-frequency switching applications, the device delivers 35 ns reverse recovery time under IF = 0.5 A / IR = 1.0 A / Irr = 0.25 A test conditions and exhibits 175 pF junction capacitance per diode at 1 MHz and 4.0 V reverse bias - critical for minimizing switching losses in SMPS and inverters.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for SF2006PT?

The SF2006PT has a V_RRM rating of 400 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version I2103). This value is specific to SF2006PT and distinguishes it from other members of the SF2001PT–SF2008PT family, which span 50 V to 600 V. Operating above this voltage risks irreversible junction breakdown.

Does SF2006PT have a center-tap configuration, and how is it implemented?

Yes, the SF2006PT uses a positive center-tap configuration with two independent diode dies sharing a common cathode terminal (Lead 2). This is physically realized in the TO-247AD package with Anode 1 (Lead 1), Cathode (Lead 2), and Anode 2 (Lead 3). The center-tap eliminates need for external transformer taps and enables full-wave rectification with minimal external components.

What is the forward voltage (V_F) of SF2006PT at 20 A and 25°C?

The SF2006PT exhibits a maximum forward voltage of 1.500 V at 20 A and 25°C, per the Electrical Specifications table. This value is measured per diode under pulsed conditions (PW = 0.3 ms) and reflects conduction loss under full-rated current - critical for thermal design and efficiency calculation in high-power applications.

Is SF2006PT qualified to AEC-Q101, and what does that mean for design use?

The base SF2006PT is not AEC-Q101 qualified; however, the variant SF2006PTH is explicitly listed as AEC-Q101 qualified in the Ordering Information section. AEC-Q101 qualification validates robustness for automotive under-hood applications, including temperature cycling, mechanical shock, and humidity testing - making SF2006PTH suitable for engine control units and lighting modules.

What is the junction-to-case thermal resistance (R_θJC) of SF2006PT, and how does it impact heatsink selection?

The SF2006PT has a typical R_θJC of 2.5°C/W, as specified in the Thermal Performance section. This low value means that for a 20 A load with 1.5 V forward drop (30 W dissipation), the junction-to-case temperature rise is only 75°C - allowing effective thermal management with modest heatsinks and eliminating need for forced airflow in many industrial applications.
