SMAJ17CA is a bidirectional transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. The device features a compact DO-214AC (SMA) surface mount package with a standoff voltage of 17 V and a maximum reverse voltage rating of 18 V, providing reliable protection against transient overvoltage events. With a breakdown voltage of 18.9 V and a working peak reverse voltage of 10 V, the SMAJ17CA delivers fast response times of less than 5.0 ns for bidirectional operation. The device is RoHS compliant and lead-free, making it suitable for modern electronic applications requiring high-reliability surge protection in compact form factors.
