STF18N60M2 概要
A power MOSFET is a type of field-effect transistor optimized for switching and amplification of power. It operates by controlling the flow of current between the drain and source terminals through an electric field applied at the gate. Power MOSFETs are fundamental building blocks in power electronics, serving as switches in DC-DC converters, AC-DC power supplies, motor drives, and lighting systems. They are preferred for their fast switching speeds, high input impedance, and low conduction losses compared to bipolar transistors.
Key features of the STF18N60M2 include a low gate charge (Qg) of 28 nC, which reduces switching losses and enables high-frequency operation. The device also offers a wide operating junction temperature range from -55°C to +150°C, making it suitable for demanding environments. Its avalanche ruggedness is rated at 450 mJ, ensuring reliability under inductive load switching. The TO-220FP package has a thermal resistance of 3.5°C/W (junction-to-case), allowing efficient heat dissipation.
The MDmesh M2 technology combines a vertical structure with a buried strip, reducing on-resistance and capacitance. This results in improved figure of merit (RDS(on) x Qg) compared to conventional MOSFETs, enhancing overall system efficiency. The device is fully RoHS compliant and halogen-free, meeting modern environmental standards.
Typical applications include switch-mode power supplies (SMPS), power factor correction (PFC) circuits, LED lighting drivers, and solar inverters. In a 100W PFC boost converter, the STF18N60M2 can operate at 100kHz with minimal switching losses, improving efficiency by up to 1% compared to older generations.
When designing with this device, ensure proper gate drive voltage (typically 10V) to achieve full enhancement. The gate-source voltage must not exceed ±25V to prevent oxide breakdown. For thermal management, use a heatsink or adequate PCB copper area to keep the junction temperature below 150°C under maximum load.

設計ノート
The STF18N60M2 has a junction-to-case thermal resistance of 3.5°C/W. For a power dissipation of 30W, the junction temperature rise is 105°C above case temperature. Use a heatsink with a thermal resistance of 1.5°C/W or better to keep the junction below 150°C at 25°C ambient. Ensure proper thermal interface material is used.
Place the gate drive circuit close to the MOSFET to minimize parasitic inductance. Use a gate resistor (typically 10 ohm) to dampen ringing. For the drain and source connections, use wide copper traces to reduce resistance and inductance. Add a snubber circuit across the drain-source to suppress voltage spikes during switching.
Do not exceed the maximum gate-source voltage of ±25V, as this can damage the oxide layer. Ensure the gate drive voltage is at least 10V to fully enhance the channel. When switching inductive loads, the avalanche energy rating (450 mJ) must not be exceeded; use a clamping circuit if necessary. Also, verify that the junction temperature does not exceed 150°C under worst-case conditions.
