The SI4490DY-T1-E3 with MOSFET RECOMMENDED ALT 781-SI4490DY-TR is a MOSFET logic-level N-channel power MOSFET manufactured by the company Vishay. This MOSFET is designed to minimize power losses in applications operating at low currents and voltages. It offers low conduction and switching losses, fast switching, and the ability to easily drive high capacitive loads. Additionally, it features a high saturated drain current of up to 7 A, 50 V drain-source breakdown voltage, a very fast body diode with a low reverse recovery charge (Qrr), and an Avalanche energy rating protection of 6mJ. This MOSFET is ideal for use in applications from digital power, to motor control for domestic appliances, to robotics and high-speed data communications.
