The SMF8.0A with 13.6V 8.89V 8V SOD-123 TVS ROHS is a unidirectional Transient Voltage Suppressor (TVS) produced by Formosa. This component protects against transients caused by electrical noise, lightning strikes, and other disturbances, and it offers operating characteristics in the form of peak power dissipation, clamping voltage, and maximum transient energy. This part has a SOD-123 package, and is RoHS compliant. The breakdoen voltages are 8V, 8.89V and 13.6V, meaning that it can protect against transients up to 13.6V.
