The CPC3909 is a 400V, N-channel depletion-mode FET with a typical on-resistance of 4.5 Ω at 25°C, available in SOT-89 and SOT-223 packages. It operates with a gate-to-source off voltage between -1.4 V and -3.1 V and handles a maximum drain current of 300 mA. The device has a maximum power dissipation of 1.1 W in the SOT-89 package and 2.5 W in the SOT-223 package, with junction-to-ambient thermal impedance of 90 °C/W and 55 °C/W respectively. It meets moisture sensitivity level MSL 1 and is ESD sensitive according to JESD-625. The part is rated for an operational temperature range of -40°C to +110°C and storage temperature from -40°C to +125°C.
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.
