FDC638P Description

Short technical summary and product information.

The FDC638P is a P-Channel enhancement-mode MOSFET manufactured by On Semiconductor using the advanced POWERTRENCH process. This process is specifically tailored to minimize on-state resistance while maintaining low gate charge for superior switching performance. The device is rated for a maximum drain-source voltage of -20V and a continuous drain current of -4.5A at 25°C ambient temperature.

 

Key electrical characteristics include a maximum on-resistance of 48mΩ at VGS = -4.5V and ID = -4.5A, with a typical value of 39mΩ. At lower gate drive of -2.5V, the typical on-resistance is 65mΩ. The gate threshold voltage ranges from 0.4V to 1.5V with a typical value of 0.8V, making it suitable for low-voltage drive applications. The device features a low typical gate charge of 10nC, enabling efficient high-frequency switching.

 

The FDC638P is well suited for battery-powered applications including load switching, power management, battery charging circuits, and DC/DC conversion. The SuperSOT-6 package offers a small footprint that is 72% smaller than a standard SO-8 package, with a low profile of only 1mm thickness, making it ideal for space-constrained designs.

 

The device is Pb-Free, Halide Free, and RoHS compliant. It operates over a junction temperature range of -55°C to +150°C and has a maximum power dissipation of 1.6W at 25°C ambient. Thermal resistance is 78°C/W junction-to-ambient and 30°C/W junction-to-case.
