The SMCJ18CA is a surface mount unidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse. It is a component that is used to protect sensitive electronics from electromagnetic and electrostatic discharges. It can withstand a pulse power of 500 watts, with a peak pulse current of 40 amperes. The SMCJ18CA is unidirectional, meaning it can only be connected one way, allowing it to only protect devices from incoming signals. Its stand-off voltage is 18 volts, meaning when the voltage reaches 18 volts, the diode will kick in and absorb any additional voltage. The SMCJ18CA is usually used in combination with a variety of integrated circuits and sensitive electronic components to provide protection from power surges and electromagnetic interference.
