The BAT54C.215 is a dual common cathode Schottky diode. This diode is typically used to prevent the reverse flow of current from one circuit to another, protect from transients, clamp voltages to a predetermined level, and to reduce power consumption. It has a package size of SOT-23, a forward voltage drop of approximately 0.315 V, and a continuous forward current rating of 200 mA. The maximum forward surge current is 150 mA with an IC max rating of 25 mA. Its operating temperature range is from -55°C to 150°C. It is a part of Nexperia's Basic BAW54 Series of Schottky diodes.
