The BAS21GWJ is a device manufactured by Nexperia and is part of their Diode – General Purpose, Power, Switching BL family of bipolar discretes. It is a single, surface mount, general purpose and high power diode which can be used to provide switching and protection circuits from excessive overloads. The BAS21GWJ offers the protection of a fast-blocking diode in a mini SOT-23 case, making it ideal for small applications. It has a low voltage drop of just 0.7 V, making it suitable for battery powered devices, and it offers low leakage current of just 4µA. The BAS21GWJ also features low capacitance and reverse recovery time, as well as consistent avalanche energy performance, making it suitable for use in a variety of voltage and power applications.
