The Littelfuse P4KE39A is a 400W unidirectional transient voltage suppression (TVS) diode from the P4KE series. It is designed to protect sensitive electronic equipment from electrostatic discharge (ESD), electrical fast transients (EFT), and induced lightning surges. The device has a reverse standoff voltage (V_RWM) of 33.3V and a clamping voltage (V_CL) of 53.9V at a peak pulse current (I_PP) of 7.6A under a 10/1000µs waveform.
This TVS diode utilizes a glass passivated junction in a DO-204AL (DO-41) axial leaded package, making it suitable for through-hole mounting. It operates over a junction temperature range of -55°C to 175°C. The device features a fast response time of typically less than 1.0ps and typical leakage current of ≤1 µA for breakdown voltages above 12.6V.
Typical applications include general purpose circuit protection in telecom, computer, industrial ICT equipment, and consumer electronics. The P4KE39A is RoHS compliant and halogen free, with a peak pulse power dissipation of 400W and a peak forward surge current rating of 60A (8.3ms half sine wave for unidirectional only).
