Typical Applications

STW30N60M2 is suitable for 6 applications: Switch-Mode Power Supplies (SMPS), Power Factor Correction (PFC), Solar Inverters, Motor Drives, Uninterruptible Power Supplies (UPS), Welding Equipment.

⚑

Switch-Mode Power Supplies (SMPS)

The STW30N60M2 is ideal for SMPS topologies such as flyback and forward converters. Its 600V breakdown voltage allows operation from rectified 380V AC mains, while the low on-resistance (0.098 ohm) minimizes conduction losses. The fast switching speed, enabled by a low gate charge of 60 nC, reduces transition losses, improving overall efficiency. In a typical flyback converter, the MOSFET switches at frequencies up to 100 kHz, and the device's avalanche ruggedness ensures reliability during voltage spikes. The TO-247 package facilitates heatsinking, allowing continuous operation at high power levels. Designers should ensure proper gate drive voltage (10-15V) and use a snubber circuit to limit voltage ringing.

⚑

Power Factor Correction (PFC)

In boost PFC circuits, the STW30N60M2 operates as the main switch, shaping the input current to be sinusoidal and in phase with the voltage. Its high voltage rating (600V) handles the boosted output voltage (typically 400V DC), and the low gate charge enables high-frequency operation (up to 200 kHz) to reduce inductor size. The device's low on-resistance minimizes conduction losses, which is critical for meeting efficiency standards like 80 PLUS. The fast body diode with low reverse recovery charge reduces switching losses during the diode's reverse recovery. For optimal performance, use a dedicated PFC controller such as the L6562A and ensure the MOSFET is mounted on a heatsink to dissipate heat from continuous operation.

πŸ”§

Solar Inverters

The STW30N60M2 is well-suited for solar inverter applications, particularly in DC-DC boost converters and inverter stages. Its 600V rating is adequate for the high DC bus voltages in photovoltaic systems (typically up to 500V). The low on-resistance reduces conduction losses, improving the overall efficiency of the inverter, which is crucial for maximizing energy harvest. The device's ruggedness against avalanche events ensures reliability in harsh outdoor environments. In a typical string inverter, the MOSFETs are used in a full-bridge topology to convert DC to AC. The fast switching speed allows for high-frequency PWM, reducing the size of output filters. Proper thermal management is essential, as the device may dissipate significant power during operation.

🏭

Motor Drives

In motor drive applications, the STW30N60M2 is used in the inverter stage to drive AC or DC motors. Its high voltage rating (600V) is suitable for industrial motor drives operating from 380V AC mains. The low on-resistance minimizes conduction losses, while the fast switching speed reduces switching losses, enabling efficient operation at PWM frequencies up to 20 kHz. The device's ruggedness against voltage transients is essential for handling inductive loads. In a typical variable frequency drive (VFD), six MOSFETs are used in a three-phase bridge. The TO-247 package allows for easy mounting on a heatsink, which is necessary to dissipate heat from continuous operation. Gate drive circuits should provide sufficient current to charge the gate quickly.

⚑

Uninterruptible Power Supplies (UPS)

The STW30N60M2 is used in UPS systems for battery charging and inverter stages. Its 600V rating allows it to handle the high DC bus voltage in online UPS systems. The low on-resistance reduces losses, improving efficiency and extending battery life. The device's fast switching capability enables high-frequency operation, reducing the size of magnetic components. In a typical UPS, the MOSFET is used in a boost converter to charge the battery and in an inverter to convert DC to AC. The device's avalanche ruggedness ensures reliability during load transients. Proper heatsinking is required to manage heat dissipation, especially during battery charging at high currents.

πŸ”§

Welding Equipment

In welding machines, the STW30N60M2 is used in the inverter stage to convert DC to high-frequency AC for the welding arc. Its high voltage rating (600V) and current capability (30A) make it suitable for the demanding conditions of welding. The low on-resistance reduces conduction losses, while the fast switching speed enables high-frequency operation, reducing the size and weight of the transformer. The device's ruggedness against voltage spikes is critical in welding applications where inductive loads are common. In a typical inverter welder, the MOSFETs are used in a full-bridge topology. The TO-247 package allows for efficient heatsinking, which is essential for continuous operation. Gate drive circuits must provide robust drive to handle high di/dt.

Key Differentiators

  • Low on-resistance of 0.098 ohm typical (vs FCH30N60)
  • Low gate charge of 60 nC (vs FCH30N60)
  • Enhanced avalanche ruggedness in -EP variant (vs STW30N60M2)

Design Notes

The STW30N60M2 has a maximum power dissipation of 250W at 25Β°C case temperature. To achieve this, a heatsink with a thermal resistance of less than 0.5Β°C/W is required. For example, at 100W dissipation, the junction temperature rise is 50Β°C (0.5Β°C/W * 100W), so with a 25Β°C ambient, the junction temperature would be 75Β°C, well within the 150Β°C limit. Always use thermal interface material (TIM) between the device and heatsink to minimize contact resistance.

For the TO-247 package, ensure the drain tab is properly soldered to a large copper area for heat spreading. The gate trace should be kept short and have a low inductance to avoid ringing. Place a gate resistor (typically 10 ohm) close to the gate pin to dampen oscillations. The source connection should be made with a low-inductance path to the gate driver return to minimize common-source inductance.

Do not exceed the maximum gate-source voltage of Β±25V, as this can damage the oxide layer. Ensure the gate drive voltage is between 10V and 15V to fully enhance the channel. When switching inductive loads, use a snubber circuit or a clamping diode to prevent voltage spikes that could exceed the 600V rating. Also, be aware of the body diode's reverse recovery characteristics; in bridge topologies, dead time should be adjusted to prevent shoot-through.
