onsemi FDN342P PowerTrench Type P-Channel MOSFET is a high-performance discrete semiconductor optimized for efficient switching applications. Designed with PowerTrench technology, this device features a shielded-gate structure that enhances charge balance, yielding a significantly lower figure of merit compared to earlier generations.
The 2 Amp maximum continuous drain current and 20 Volt maximum drain-source voltage provide reliable operation within low-voltage switching circuits. Its enhancement mode channel supports precise control, ideal for synchronous rectification and other power management functions.
The device is housed in a compact 3-Pin SOT-23 surface mount package, measuring 2.92 mm in length, 1.4 mm in width, and 940 μm in height, enabling high-density PCB layouts without compromising thermal performance.
Characteristic features of the FDN342P include a low maximum drain-source resistance of 80 milliohms, a maximum power dissipation of 500 milliwatts, and a typical gate charge of 6.3 nanocoulombs, allowing for rapid switching and minimal losses. The maximum gate-source voltage tolerates ±12 volts, ensuring protection against voltage surges.
Operating temperature spans from −55 to 150 degrees Celsius, making it suitable for demanding industrial and automotive environments where thermal stability is critical. The device's soft body diode performance effectively eliminates the need for additional snubber circuits, improving system efficiency.
Maximum continuous drain current of 2 Amperes. Rated for a maximum drain-source voltage of 20 Volts. PowerTrench series offers enhanced power density and efficiency. Small gate charge enables fast switching suitable for power supplies.
Compact SOT-23 package supports surface mounting on high-density PCBs. Wide operational temperature range from -55°C to 150°C. Maximum power dissipation at 500 milliwatts. Maximum gate-source voltage of ±12 Volts. Device dimensions: 2.92 mm length, 1.4 mm width, 940 μm height.
This PowerTrench P-Channel MOSFET is ideal for industrial, electronic component manufacturing, power management, and HVAC applications requiring robust, efficient low-voltage switching elements. Its surface mount configuration and compact size also make it favorable for consumer electronics and automotive electronics designs.
