The FDV303N is an N-Channel enhancement mode field effect transistor produced using onsemi's proprietary, high cell density, DMOS technology. This device is designed for applications requiring low on-state resistance at low gate drive voltages, making it suitable for battery-powered circuits.
Key electrical specifications include a maximum drain-source voltage of 25V, continuous drain current of 680mA at 25°C ambient, and a pulsed drain current rating of 2A. The on-resistance is 450mOhm maximum at 4.5V gate drive and 600mOhm maximum at 2.7V gate drive. The device features a gate threshold voltage of 1.5V maximum and includes a gate-source Zener diode for ESD protection rated at 6kV HBM.
The FDV303N is offered in the compact industry standard SOT-23 surface mount package (SOT-23-3). It is supplied in tape and reel packaging with a standard quantity of 3000 pieces per reel. The device is Pb-Free, Halogen Free/BFR Free, and RoHS compliant.
