Taiwan Semiconductor Corporation SF3006PTH

Overview

SF3006PTH from Taiwan Semiconductor is a dual-die, positive-center-tap superfast rectifier in TO-247AD (TO-3P) package, rated for 30 A average forward current, 400 V repetitive peak reverse voltage (V_RRM), and 35 ns reverse recovery time (t_rr). It delivers low forward voltage (1.30 V at 15 A, 25°C) and high thermal efficiency with 1.0 °C/W junction-to-case thermal resistance, enabling use in high-frequency DC/DC converters and snubber circuits.

For engineers reviewing the SF3006PTH datasheet, SF3006PTH pinout, SF3006PTH application, or SF3006PTH equivalent, key selection considerations include its AEC-Q101 qualification, dual-die center-tap configuration, 400 V V_RRM, 30 A I_F, and TO-247AD mechanical compatibility for high-power industrial and automotive power supplies.

Technical Context

The SF3006PTH integrates two identical silicon rectifier dies in a single TO-247AD package with shared cathode and isolated anodes - forming a positive-center-tap dual rectifier topology. Its superfast recovery (t_rr = 35 ns) and low Q_rr support operation in switching frequencies up to several hundred kHz.

Designed for high-efficiency power conversion, it features glass-passivated junctions, matte tin-plated leads compliant with J-STD-002, and meets JESD 301 Class 2 whisker resistance. The device operates across –55°C to +150°C junction temperature range with 300 A non-repetitive surge capability (8.3 ms half-sine).

FAQ

What is the maximum junction temperature rating for SF3006PTH?

The SF3006PTH has a maximum junction temperature (T_J) of +150°C and a minimum of –55°C. This rating is validated per AEC-Q101 stress testing and applies across its full electrical operating range. Derating curves in the official datasheet specify that at case temperatures above 100°C, the average forward current must be reduced linearly to maintain safe thermal operation. The SF3006PTH achieves this with a low 1.0 °C/W R_θJC.

Is SF3006PTH pin-compatible with SF3006PT?

Yes, SF3006PTH is mechanically and electrically identical to SF3006PT except for AEC-Q101 qualification. Both share the same TO-247AD package outline, pin assignment (A1–A2–K), marking code, and absolute maximum ratings. The "H" suffix denotes additional automotive-grade screening and traceability - no PCB or layout changes are needed when upgrading from SF3006PT to SF3006PTH.

What does the "H" suffix mean in SF3006PTH?

The "H" suffix in SF3006PTH indicates full AEC-Q101 qualification, including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. It also signifies enhanced traceability, lot-level documentation, and extended temperature range validation (–55°C to +150°C). The SF3006PTH retains all electrical and thermal specs of the base SF3006PT while adding automotive-grade reliability assurance.

What is the reverse recovery time (t_rr) of SF3006PTH and how is it measured?

The SF3006PTH has a typical reverse recovery time (t_rr) of 35 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A, and T_J = 25°C. This value reflects the time required for minority carriers to clear after forward conduction ceases - critical for minimizing switching loss in high-frequency converters. The SF3006PTH's t_rr is confirmed in the official TSC datasheet Version J2103, Figure 6.

Can SF3006PTH be used in a single-diode configuration?

Yes, SF3006PTH can be used as a single diode by connecting one anode (A1 or A2) and the common cathode (K), leaving the other anode unconnected and insulated. However, doing so forfeits the thermal and current-sharing benefits of the dual-die design. The unused anode must be electrically isolated to avoid parasitic conduction paths. For dedicated single-diode applications, TSC offers the SF3006PT variant in single-die TO-220AC - though it lacks AEC-Q101 qualification.
