ONGThe 1.5KE150CA with 207V 142.5V 128V DO-201 TVS ROHS is an electronic component, manufactured by DOWOONG, that serves as a transient voltage suppressor (TVS) or voltage clamp device. It is designed to protect sensitive electronic components from voltage spikes caused by over-voltage and electrostatic discharge (ESD). The DO-201 encapsulation helps the device stand up to harsh environments, while the RoHS certification guarantees hazardous materials have been excluded from the construction process. The 207V, 142.5V, and 128V indicate the breakdown voltage, peak pulse power dissipation, and peak pulse current rating of the 1.5KE150CA, respectively.
