The SMAJ110CA is a bi-directional surface mount transient voltage suppressor (TVS) diode, designed to protect sensitive electronic components from voltage transients induced by downstream wiring, cables, lightning, and electrostatic discharge. It is manufactured by Changjing Electronics Technology and conforms to the RoHS environmental standard. It has a 177V working voltage, 122V clamping voltage, and 110V surge current rating. When exposed to an overvoltage event, the diode functions by allowing a controlled amount of current to flow, reducing the voltage and dissipating the excess energy. The SMAJ110CA is embedded with Automotive-grade, positive temperature coefficient (PTC) polymer, allowing the device to self-repair after every transient surge event.
