3KP30CA Description

Short technical summary and product information.

The 3KP30CA is a 3000W transient voltage suppression diode from Littelfuse, part of the 3KP series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. This bidirectional device offers a reverse standoff voltage of 30V and a clamping voltage of 48.4V at a peak pulse current of 62A (10/1000μs waveform). It features a fast response time of less than 1ps and provides ESD protection up to 30kV (air and contact) per IEC 61000-4-2. The device is housed in a P600 axial leaded package and supports through-hole mounting. It operates over a junction temperature range of -55°C to 175°C. Typical applications include I/O interfaces, VCC bus protection, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The 3KP30CA is RoHS compliant and halogen free.
