Taiwan Semiconductor Corporation SF1607PT

Overview

SF1607PT from Taiwan Semiconductor is a dual-die, positive-center-tap super fast rectifier in TO-247AD (TO-3P) package, rated for 16 A average forward current, 500 V repetitive peak reverse voltage (V_RRM), and 35 ns reverse recovery time (t_rr). It delivers low forward voltage (1.70 V at 8 A, 25°C), low thermal resistance (2°C/W), and supports high-efficiency DC-DC converters and snubber circuits.

For engineers reviewing the SF1607PT datasheet, SF1607PT pinout, SF1607PT application, or SF1607PT equivalent, key selection considerations include its 500 V V_RRM, dual-center-tap configuration, TO-247AD mechanical compatibility, AEC-Q101 qualification eligibility (via SF1607PTH variant), and verified 150 A non-repetitive surge rating.

Technical Context

The SF1607PT integrates two identical silicon die in a single TO-247AD package with shared cathode and isolated anodes - forming a positive-center-tap dual rectifier topology ideal for full-wave center-tapped transformer designs. Its glass-passivated junctions and optimized doping enable superfast recovery (t_rr = 35 ns) while maintaining low leakage (I_R ≤ 10 µA at 25°C).

This device operates across –55°C to +150°C junction temperature range, with thermal resistance R_θJC = 2°C/W enabling high-power dissipation without forced cooling in industrial switching supplies. Its 1.70 V forward voltage at 8 A reflects optimized conduction efficiency for 500 V-class fast recovery applications.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and power discrete manufacturer headquartered in Hsinchu, Taiwan, serving global industrial, computing, and automotive markets since 1979.

The SF1601PT–SF1608PT series was designed specifically for high-efficiency, high-reliability rectification in switching power supplies - emphasizing low V_F, fast t_rr, robust thermal performance, and AEC-Q101-ready variants for automotive-grade deployment.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for SF1607PT?

The SF1607PT has a V_RRM rating of 500 V, confirmed in the Absolute Maximum Ratings table on page 2 of the official TSC datasheet (Version G2103). This value is specific to SF1607PT and distinguishes it from adjacent variants like SF1606PT (400 V) and SF1608PT (600 V). The 500 V rating supports designs operating from 380–400 VDC bus voltages with appropriate derating.

Is SF1607PT pin-compatible with SF1607PTH?

Yes, SF1607PT and SF1607PTH share identical TO-247AD (TO-3P) package dimensions, pinout, and thermal/mechanical specifications. The only difference is qualification: SF1607PTH is AEC-Q101 tested and marked with "H" suffix, while SF1607PT is the standard industrial version. Both use the same Anode 1 / Anode 2 / Cathode terminal assignment.

What is the forward voltage (V_F) of SF1607PT under typical operating conditions?

The SF1607PT exhibits a typical forward voltage of 1.70 V at 8 A and 25°C junction temperature, as specified in the Electrical Specifications table (page 2, Version G2103). This value increases with temperature and current - e.g., ~1.85 V at 16 A and 125°C - and is measured using 0.3 ms pulse width to avoid self-heating effects.

Does SF1607PT have a center-tap configuration, and how is it implemented?

Yes, SF1607PT implements a positive-center-tap configuration via dual isolated anodes (A1, A2) and a shared cathode (K). This internal structure eliminates the need for external diode pairing in full-wave rectifier topologies. The marking diagram and mechanical outline confirm the three-terminal TO-247AD layout matches this dual-die, common-cathode construction.

What is the thermal resistance (R_θJC) of SF1607PT, and how does it impact heatsink design?

The SF1607PT has a typical junction-to-case thermal resistance (R_θJC) of 2°C/W, per the Thermal Performance table (page 2, Version G2103). This low value allows efficient heat transfer from die to heatsink - for example, at 16 A and 1.70 V V_F, power dissipation is ~27 W, resulting in only ~54°C junction rise above case temperature, simplifying passive thermal management.
