The Littelfuse P4KE6.8CA is a 400W bi-directional Zener TVS diode designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 5.8V and a maximum clamping voltage of 10.5V at a peak pulse current of 39A (10/1000μs waveform). This diode offers fast response time of less than 1.0 ps from 0V to breakdown voltage, making it suitable for high-speed signal line protection.
This TVS diode is housed in a through-hole DO-204AL (DO-41) package with axial leads and a tin terminal finish. It is rated for operating junction temperatures from -55°C to 175°C and provides ESD protection up to 30kV (air and contact) per IEC 61000-4-2. The device is RoHS3 compliant, halogen free, and lead free (Pb-free E3), with a flammability rating of UL 94 V-0.
Key electrical characteristics include a typical temperature coefficient of 0.1%/°C, steady state power dissipation of 1.5W (infinite heat sink at TL=75°C), and peak forward surge current capability of 60A (8.3ms single half sine wave). Typical thermal resistance is 60°C/W junction-to-lead and 100°C/W junction-to-ambient. The part is suitable for protecting I/O interfaces, VCC bus, and other circuits in telecom, computer, industrial, and consumer electronics.
