Compared to other MOSFET transistors in its class, the STL28N60M2 can deliver up to 50% lower switching losses and 35% lower conduction losses, which translates into significant energy savings in high-power applications such as motor drives, power supplies, and industrial automation.

High reliability and robustness

Another advantage of STL28N60M2 is its high reliability and robustness. This MOSFET transistor is designed to withstand voltage spikes, thermal shocks, and other stresses that can cause failure or degradation in the long term. It also features a built-in fast diode that enables fast and smooth switching, reducing EMI and improving system performance.

Versatile flexibility

The STL28N60M2 is a versatile transistor that can work with a variety of gate voltage levels (-10V to 20V), gate charge values (45nC), and heatsink configurations, making it suitable for different circuit designs and operating conditions. It also has a low gate input capacitance (Ciss), which minimizes the drive requirements of the gate driver and improves switching speed and accuracy.

Applications of STL28N60M2

Motor control

With its high power rating and low Rds(on), the STL28N60M2 is an ideal MOSFET transistor for motor control applications such as servo drives, BLDC motor drivers, and stepper motor controllers. By minimizing the switching losses and thermal stress in the MOSFET, it can improve the efficiency and responsiveness of the motor, reduce noise and vibration, and extend the lifespan of the system.

Power supplies

In power supply circuits like DC-DC converters, the STL28N60M2 can help reduce the energy losses and increase the power density by handling the high voltage and current levels more efficiently and reliably than traditional bipolar transistors. It can also support various topologies such as half-bridge, full-bridge, and forward converters, and operate at high switching frequencies (up to 100kHz) without sacrificing performance or complexity.

Industrial automation

In industrial applications like programmable logic controllers (PLCs), robotics, and welding machines, STL28N60M2 provides an excellent balance between power, speed, and ruggedness, allowing them to operate in harsh environments with minimal maintenance and downtime. It can handle voltage spikes, inductive loads, and short circuits, and provide reliable and fast switching in both high- and low-side configurations.

Tips on using STL28N60M2 effectively

To harness the full potential of STL28N60M2, here are some practical tips to keep in mind:

Use a proper gate driver IC that can deliver enough voltage and current to drive the MOSFET efficiently and protect it from overvoltage and overcurrent events.

Keep the ambient temperature and junction temperature within the recommended range (usually -55°C to 175°C) to avoid thermal runaway and degradation.

Do not exceed the maximum voltage, current, and power ratings of the MOSFET, as this can cause permanent damage or failure.

Consider the EMI and ripple effects in your circuit design and add proper filtering and decoupling components to minimize them.

Use a heatsink with sufficient thermal resistance and thermal capacitance to dissipate the heat generated by the MOSFET and avoid overheating.

By following these guidelines, you can maximize the performance, efficiency, and reliability of STL28N60M2 in your applications and achieve the best results possible.
