3KP30A Description

Short technical summary and product information.

The Littelfuse 3KP30A is a 3000W transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 30V and a maximum clamping voltage of 48.4V, making it suitable for 24V or 30V bus protection. The device can handle peak pulse currents up to 62A (10/1000μs waveform) and peak forward surge currents up to 300A (8.3ms single half sine wave, unidirectional only).

 

This TVS diode is built with a glass passivated chip junction in a P600 axial package, providing robust protection for I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronic applications. It features a fast response time of typically less than 1.0 ps from 0V to breakdown voltage, and excellent clamping capability. The device is rated for operating junction temperatures from -55°C to 175°C, with a steady state power dissipation of 7.0W at TL=75°C.

 

The 3KP series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. The P600 axial package is suitable for through-hole mounting, providing robust mechanical and thermal performance. The device is RoHS compliant, halogen-free, and lead-free (Pb-free E3), with a flammability rating of V-0 per UL.
