SMLJ30CA is a transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. This bidirectional device features a 30 V standoff voltage with a 5% tolerance and is housed in a compact surface mount DO-214AB (SMC) package for space-constrained applications. The device delivers 3000 watts of peak power dissipation and exhibits fast response times of less than 5.0 nanoseconds from 0 V to minimum breakdown voltage. With working peak reverse voltage of 30 V and breakdown voltage up to approximately 45.3 V, the SMLJ30CA provides reliable transient protection for sensitive electronic circuits in modern portable devices and consumer electronics.
