SMLJ20CA is a transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. This bidirectional device features a working peak reverse voltage of 20 V with a standoff voltage of 5.0 V, and is housed in a compact surface mount DO-214AB (SMC) package. The device offers fast response times of less than 5.0 ns and can dissipate up to 3000 watts of peak power, making it highly effective for protecting sensitive electronic circuits from transient overvoltage events. SMLJ20CA is RoHS compliant and represents the preferred choice for new designs, offering reliable protection in applications requiring compact form factors and high surge handling capability.
