SMA6J13A is a unidirectional transient voltage suppressor diode designed for surge and ESD protection in compact DO-214AC (SMA) surface mount package. The device features a working peak reverse voltage of 13 V, a reverse breakdown voltage range of 14.4 to 15.9 V, and a maximum reverse peak voltage of 21.5 V. It delivers 600 watts of peak pulse power dissipation and exhibits typical fast response times of less than 1.0 picosecond from 0 V to breakdown voltage. The SMA6J13A is ideal for protecting power buses, I/O interfaces, and sensitive circuits in telecom, computer, industrial, and consumer electronics applications where reliable overvoltage transient protection is essential.
