Bourns SMA6J18A Surge Protector Diode

The Bourns SMA6J series transient voltage suppressor diode offers reliable, high-energy surge protection in a compact SMAb package designed for surface mount applications. With a working peak reverse voltage from 5 V to 43 V, these diodes provide fast response times less than 1.0 picosecond from 0 V to breakdown voltage, ensuring swift protection of power lines, data interfaces, and sensitive electronics. Ideal for telecom, industrial, computer, and consumer electronic applications, they support overvoltage transient suppression with a power dissipation capacity of 600 watts, and are RoHS compliant, making them a robust choice for surge and ESD protection needs.
