The SBDF4045TCTB is a dual common cathode, 40A Schottky Barrier Diode (SBD) with 0.47V@20A breakdown voltage, 80uA@45V electrostatic discharge current, and a TO-220F package. It is manufactured by Changjing Electronics Technology and meets RoHS standards. This diode has a low forward voltage drop and a fast switching speed that make it ideal for high-frequency applications and for protecting sensitive products from high-current, high-voltage transients.
