P4KE6.8A – 6.8V 400W Uni-Directional TVS Diode | DO-41 | Low-Voltage DC Surge Protector SEP

The P4KE6.8A is a 400W uni-directional transient voltage suppressor engineered for protecting low-voltage DC rails and sensitive electronics from ESD, lightning pulses, and inductive switching spikes. It provides a 5.8V standoff voltage with breakdown at 6.45–7.14V, ensuring accurate and fast clamping during surge events. With a clamping voltage of 10.5V and a peak pulse capability of 39A, it delivers robust surge immunity while maintaining low standby leakage. The DO-41 axial package supports reliable through-hole assembly for industrial, consumer, and communication interfaces.
