The CPC3902 is a 250V, N-channel, depletion-mode MOSFET in an SOT-223 package, designed for high-power applications such as current regulation, normally-on switching, and solid state relays. It has a maximum on-resistance of 2.5Ω at 25°C and a gate-to-source off voltage range of -1.4V to -3.1V. The device supports a continuous drain current of 400mA and a total package dissipation of 1.8W when mounted on a 1"×1" 2 oz. copper FR4 board. Thermal resistance is 14°C/W from junction to case and 55°C/W from junction to ambient. It operates from -55°C to +110°C with a maximum junction temperature of +125°C. The part meets MSL 1 moisture sensitivity and ESD sensitivity per JESD-625, with a reflow soldering profile of 260°C for 30 seconds. Input capacitance is 230pF at VGS = -3.5V, and reverse transfer capacitance is 9.5pF at 1MHz.
Our N-channel depletion mode field effect transistors (FET) utilize a proprietary third generation vertical DMOS process. The third generation process realizes world-class, high voltage MOSFET performance in an economical silicon gate process. The vertical DMOS process yields a robust device for high power applications with high input impedance. These highly reliable FET devices have been used extensively in our solid state relays for industrial and telecommunications applications.
