The 5KP18A is a Zener-type transient voltage suppression (TVS) diode from Littelfuse Inc. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. With a reverse standoff voltage of 18V and a maximum clamping voltage of 29.2V at a peak pulse current of 174.7A, it provides robust protection for 18V rated circuits. The device offers a peak pulse power dissipation of 5kW (5000W) for a 10/1000µs waveform. Key features include fast response time (<1.0 ps), low dynamic resistance, and ESD protection up to 30kV (air and contact) per IEC 61000-4-2. The TVS diode is housed in a P600 axial leaded package (through-hole mounting) and operates over a junction temperature range of -55°C to 175°C. It is RoHS compliant, halogen-free, and has a Pb-free E3 terminal finish. Typical applications include general-purpose protection of I/O interfaces, VCC buses, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
