20KPA24A Description

Short technical summary and product information.

The Littelfuse 20KPA24A is a 20000W axial leaded TVS diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It is part of the 20KPA series, which offers excellent clamping capability and a fast response time of typically less than 1ps from 0 Volts to breakdown voltage.

 

Key electrical specifications include a reverse standoff voltage of 24V, a clamping voltage of 41.2V, and a breakdown voltage range with a minimum of 26.7V. The device can handle a peak pulse current of 490.3A and a peak pulse power dissipation of 20kW. It also features a peak forward surge current rating of 400A.

 

The 20KPA24A is housed in a through-hole P600 axial package and is rated for an operating temperature range of -55°C to 175°C. It features a glass passivated chip junction and is available with matte tin lead-free plating. The device is RoHS compliant and halogen free.
