The P6KE33CA with 45.7V, 31.4V and 28.2V DO-15 (DO-204AC) TVS ROHS is a transient voltage suppressor designed and produced by Yageo. It is a type of component which behaves like a two-terminal component and is used to protect electronic equipment from voltage spikes in power lines. It features zener diode elements, providing a fast response time, and is designed and manufactured to meet Rohs (restriction of hazardous substances) requirements. The P6KE33CA is rated to 45.7V, 31.4V, and 28.2V, which are the maximum steady state voltages that the device can handle and withstand. It has a DO-15 (DO-204AC) package, and is suitable for a wide range of applications.
