The P6KE6.8CA is an automotive-grade transient voltage suppressor (TVS) made by Jinkaisheng in a DO-15 package. It is designed to protect sensitive electronic components from voltage spikes caused by electrical transients. This particular TVS is designed for protection against reverse polarity voltage spikes up to 10.5V, and can withstand maximum peak pulse power dissipation of 500W. It has a nominal breakdown voltage of 6.45V and a peak clamping voltage of 5.8V. The P6KE6.8CA is RoHS compliant, meaning it meets all current applicable environmental standards.
