P4KE220A Description

Short technical summary and product information.

The P4KE220A is a 400W transient voltage suppression (TVS) diode from Littelfuse's P4KE series, designed to protect sensitive electronic equipment from voltage transients induced by lightning, ESD, and EFT events. It features a reverse standoff voltage (V_RWM) of 185V and a maximum clamping voltage of 328V at the peak pulse current of 1.3A (10/1000μs waveform).

 

The device offers a fast response time of less than 1.0 ps from 0V to the breakdown voltage, ensuring rapid clamping of transient events. It is unidirectional with a single die, and provides a peak forward surge current capability of 60A (8.3ms half sine wave). The steady state power dissipation is 1.5W at a lead temperature of 75°C on an infinite heat sink.

 

The P4KE220A is packaged in a through-hole DO-204AL (DO-41) axial leaded package, suitable for general purpose circuit protection applications. It operates over a junction temperature range of -55°C to 175°C and is RoHS3 compliant, halogen free, and lead-free (Pb-Free E3).
