The 15KP280CA with 454.5V, 312.8V, 280V, P600 TVS ROHS manufactured by DOWO is a transient voltage suppressor (TVS) device. It is specifically designed to protect circuits from transients and overvoltage events. This device is comprised of four voltage varistors, as indicated by the 454.5V, 312.8V, and 280V P600 parameters, and is RoHS compliant. This device is primed for use in applications where transient voltages need to be suppressed, such as telecommunication systems, motor drives, and power supplies.
