AO4842 Dual N-Channel Enhancement Mode Field Effect Transistor

The AO4842/L uses advanced trench technology to provide excellent RDS ON and low gate charge. The two MOSFETs make a compact and efficient switch and synchronous rectifier combination for use in buck converters. AO4842 and AO4842L are electrically identical. -RoHS Compliant -AO4842L is Halogen Free
