Infineon SPP07N60C3 600V CoolMOS™ Power Transistor: Datasheet, Application Circuit, and Pinout

The Infineon SPP07N60C3 is a 600V N-channel power transistor belonging to the renowned CoolMOS™ C3 series, a technology that sets a benchmark in high-voltage power conversion. Designed for exceptional efficiency and reliability in switched-mode power supplies (SMPS), this MOSFET is engineered to minimize switching losses and enhance thermal performance, making it a preferred choice for demanding industrial, telecom, and consumer applications.

Key Features and Datasheet Highlights

The datasheet for the SPP07N60C3 reveals several standout specifications. It boasts a drain-source voltage (VDS) of 600V, ensuring robust operation in high-voltage environments. With a continuous drain current (ID) of 7.2A at 25°C and a remarkably low on-state resistance (RDS(on)) of 0.38Ω, it significantly reduces conduction losses. The superior switching performance is a hallmark of the CoolMOS™ C3 technology, achieved through low gate charge (QG) and output capacitance (COSS). This leads to higher efficiency, especially in hard-switching topologies like flyback and power factor correction (PFC) circuits. Furthermore, the device features a fast intrinsic body diode and high dv/dt capability, enhancing its ruggedness and reliability.

Typical Application Circuit

A common application for the SPP07N60C3 is in a high-frequency quasi-resonant (QR) flyback converter, a popular topology for AC/DC adapters and auxiliary power supplies. In this circuit:

The MOSFET acts as the main switching element, controlled by a dedicated PWM controller IC.

The gate is driven through a low-impedance driver circuit to ensure fast turn-on and turn-off, minimizing switching losses.

A snubber network (often an RCD clamp) across the drain and source is used to suppress voltage spikes and protect the transistor.

The primary side winding of the transformer, connected to the drain, stores and transfers energy to the secondary output.

This design leverages the low RDS(on) and excellent switching characteristics of the SPP07N60C3 to achieve high power density and efficiency, often exceeding regulatory standards for energy consumption.

Pinout Configuration

The SPP07N60C3 is offered in the industry-standard TO-220 full-pack (insulated) package. Its pinout is straightforward:

1. Gate (G): This pin receives the control signal from the driver IC. A series gate resistor is typically used to prevent oscillations.

2. Drain (D): Connected to the high-voltage rail and the primary winding of the transformer, this pin handles the main load current.

3. Source (S): This is the common return path for both the drain current and the gate driver current. It is connected to ground in most circuits.

The full-pack insulation allows for easy mounting to a heatsink without the need for an isolating mica washer, simplifying the assembly process and improving thermal management.
