The 40CTQ045PBF is a 40A, 45V FET Schottky diode from Vishay. It is a surface mount ultra-low forward voltage, low leakage device with a balun voltage output. It is constructed with a special epitaxial silicon for low forward voltage performance. This device is especially suitable for automotive applications due to its low-power dissipation, low reverse leakage, and low forward voltage performance. Its maximum forward current rating is 40 amps, and its maximum reverse voltage rating is 45 volts. This Pb-free product is RoHS compliant.
