The SMAJ15CA is a 16.4A, 1uA, 400W, 24.4V, 16.7V, 15V, 18.5V bi-directional SMA TVS (transient voltage suppressor) manufactured by Liown. It is a RoHS certified part and is designed to protect against electrostatic discharge (ESD), electrical overstress (EOS) and lightning-induced voltage transients. The unit is capable of handling transient energy up to 400 watts and can be used in both AC and DC applications. The SMAJ15CA features a high surge current capability of up to 16,400 Amperes (8,200A per line), a typical peak pulse power of 86.4 kW (for a 10 µs waveform), and an absolute maximum peak pulse power of 129.6 kW (for a 10 µs wave forms). Additionally, the device has an integrated snubber circuit for enhanced performance.
