The SMAJ100A 2.5A 1uA 162V 400W 111V 100V 123V unidirectional SMA TVS ROHS [Surface Mount Automotive Transient Voltage Suppressor] is one of many protective components manufactured by Liown. This device helps protect sensitive electronic components and circuit breakers from overvoltage or overcurrent, and is ideal for use in areas which are subject to external high voltage and heavy current flows, such as telecommunications, automotive, computing, and military/aerospace applications. It is RoHS [Restriction of Hazardous Substances] compliant and conforms to ISO 9001 and UL 94V-O standards. This SMAJ series TVS is unidirectional, and is rated for a maximum clamp voltage of 162V with a holding current of 2.5A and a peak surge current of 400W. It is rated for peak pulse power dissipation of 111V, 100V, 123V, and can dissipate up to 1uA.
