The SMAJ220CA with 1.1A 1uA 356V 400W 246V 220V 272V Bi-Directional SMA TVS ROHS is a surface mount, unidirectional, or bidirectional, transient voltage suppression (TVS) diode manufactured by Liown. It is capable of dissipating power up to 400 watts and is made from two monolithically integrated silicon avalanche diodes, which are specifically designed to protect circuits from voltage transients caused by lightning, AC power-crossing, inductive load switching, and other events. The SMAJ220CA has very low clamping voltage, high surge capability, and fast response time and is compliant with RoHS (Restriction of Hazardous Substances) regulations. It is available in various case sizes and is suitable for automated pick and place, reflow soldering, and wave soldering applications.
