P4KE6.8CA – 6.8V 400W Bi-Directional TVS Diode | DO-41 | AC & Signal Line Surge Protector SEP

The P4KE6.8CA is a 400W bi-directional transient voltage suppressor designed for AC and bidirectional signal line protection. With a symmetrical breakdown range of 6.45–7.14V, it clamps surges in both polarities, making it ideal for protecting interfaces exposed to alternating voltages, inductive switching, and lightning disturbances. The device supports a 5.8V standoff rating, 10.5V clamping, and 39A pulse capability, ensuring strong suppression while maintaining minimal leakage. Its DO-41 package offers rugged through-hole reliability for industrial, telecom, automation, and consumer equipment.
