Taiwan Semiconductor Corporation SF3002PTH

Overview

SF3002PTH from Taiwan Semiconductor is a 30A, 100V AEC-Q101-qualified super fast rectifier in TO-247AD package, featuring dual-die positive-center-tap configuration, 35ns reverse recovery time, 0.95V forward voltage at 15A/25°C, and 1°C/W junction-to-case thermal resistance - used in automotive-grade DC-DC converters and snubber circuits.

For engineers reviewing the SF3002PTH datasheet, SF3002PTH pinout, SF3002PTH application, or SF3002PTH equivalent, key selection criteria include its 100V V_RRM, AEC-Q101 qualification, dual-die center-tap topology, low thermal resistance, and compatibility with high-frequency switching topologies requiring fast recovery and low conduction loss.

Technical Context

The SF3002PTH integrates two identical silicon rectifier dies in a single TO-247AD (TO-3P) package with shared cathode and isolated anodes, forming a positive-center-tap configuration ideal for full-wave rectification without external center-tapped transformers. Its superfast recovery (t_rr = 35ns) and low Q_rr minimize switching losses in high-frequency SMPS.

Designed for automotive under-hood environments, it supports continuous operation from −55°C to +150°C junction temperature, with glass-passivated junctions, matte tin-plated leads compliant to J-STD-002, and UL 94V-0 molding compound - meeting AEC-Q101 stress test requirements including temperature cycling, HTRB, and HTGB.

FAQ

What does the "H" suffix in SF3002PTH signify?

The "H" suffix in SF3002PTH explicitly denotes AEC-Q101 qualification per the manufacturer's ordering code convention. This means the SF3002PTH has undergone full stress testing-including temperature cycling, high-temperature reverse bias, and humidity testing-specifically validated for automotive under-hood applications. Non-H variants like SF3002PT lack this certification and are intended for commercial/industrial use only.

Is SF3002PTH pin-compatible with SF3001PTH or SF3003PTH?

Yes, all SF300xPTH devices share identical TO-247AD (TO-3P) mechanical footprint, pinout, and dual-die center-tap configuration. The only difference is rated V_RRM: SF3001PTH = 50V, SF3002PTH = 100V, SF3003PTH = 150V. Engineers may substitute within the same board layout provided voltage derating and thermal margins remain acceptable for the target application.

What is the maximum recommended case temperature for SF3002PTH in continuous operation?

The SF3002PTH supports continuous operation up to +150°C junction temperature, and its 1°C/W R_θJC implies a maximum practical case temperature of approximately +140°C when dissipating 10W (ΔT = R_θJC × P_D). For reliable long-term operation in automotive environments, maintain case temperature ≤125°C using appropriate heatsinking and airflow per the derating curve in Figure 1 of the datasheet.

Does SF3002PTH require a thermal pad or thermal interface material when mounted to a heatsink?

No, the SF3002PTH's low R_θJC of 1°C/W and flat metal tab allow direct bolt-down mounting to a heatsink without mandatory thermal interface material. However, using a thin, high-conductivity thermal pad (e.g., 0.1mm silicone-based) improves interfacial contact uniformity and reduces effective thermal resistance by ~0.2–0.3°C/W - especially beneficial in high-vibration automotive applications where mechanical stability is critical.

How does the dual-die structure of SF3002PTH affect its use in freewheeling applications?

In freewheeling applications, the SF3002PTH's dual-die positive-center-tap structure allows either anode to serve as independent freewheeling paths - e.g., one anode for phase A and the other for phase B in a dual-output converter. Its matched die characteristics ensure symmetrical V_F and t_rr, preventing current imbalance. Unlike single-diode packages, it eliminates need for two discrete devices, reducing PCB area and parasitic inductance.
