The P4SMA13CA transil diode is a 400W, 13V, 22A, bidirectional, ±5%, SMA diode manufactured by Yangjie. It provides an increased level of reliability due to its unidirectional characteristics which helps in preventing electrical overshoot. It is a surface mount device (SMD) which can easily be assembled onto a printed circuit board (PCB). The device is also suitable for both commercial and industrial applications. It features low inductance, fast switching and low leakage current. It also features a low thermal resistance and a high power dissipation capability. This diode is ideal for multiple applications such as transient overload protection, surge protection and reverse polarity protection.
