30KPA30CA Description

Short technical summary and product information.

The 30KPA30CA is a bidirectional TVS diode from Littelfuse's 30KPA Series, designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. It offers a peak pulse power dissipation of 30kW (10/1000μs waveform) and a reverse standoff voltage of 30V. The clamping voltage is 55.2V, and the breakdown voltage ranges from 33.51V to 36.86V at 50mA.

 

This device features a fast response time of less than 1.0ps and low dynamic resistance. It is rated for a peak pulse current of 548.9A and has a steady state power dissipation of 8.0W on an infinite heat sink at 75°C lead temperature. The operating junction temperature range is -55°C to 150°C, and storage temperature is -55°C to 175°C.

 

The 30KPA30CA is housed in a P600 axial package with tin-plated terminals, suitable for through-hole mounting. It is RoHS compliant, halogen free, and Pb-free (E3). The device is UL Recognized to UL 497B as an isolated loop circuit protector and meets flammability rating UL 94 V-0. ESD protection is rated at 30kV air and 30kV contact per IEC 61000-4-2.
