The Littelfuse 5KP250A-B ESD suppressors/TVS diodes are a high-power, axial form, electrostatic discharge protection device rated at 250W for 8/20µs with 1.0kA of surge capability. This compact, surface-mount device is fabricated using a substrate technology known as PolyZen, which allows for greater surge withstand and performance characteristics from low standoff (0402) to tall standoff (1210) components. It also provides ESD clamping above the 15KV air discharge generator limit, making it suitable for use in applications where ESD protection is required, such as USB, USB-C, parallel ports, serial ports, HDMI, and VGA. It comes in an SMT package for soldering onto PCBs. As well as superior ESD performance, the 5KP250A-B also has low leakage current.
