P4KE530A

The P4KE530A is a 400W peak pulse power transient voltage suppression (TVS) diode from Littelfuse Inc. It is designed to protect sensitive electronic equipment from voltage transients such as EFTs, ESD, and induced lightning. The device offers a reverse standoff voltage of 477V and a maximum clamping voltage of 725V under a 10/1000μs waveform. It can handle a peak pulse current of 550mA. The response time is typically less than 1.0ps from 0V to breakdown voltage minimum. The P4KE530A is a unidirectional diode with a single channel. It is not intended for power line protection. Typical applications include protection of I/O interfaces, VCC bus lines, and other vulnerable circuits in telecom, computer, industrial ICT equipment, and consumer electronics. The device supports an operating junction temperature range of -55°C to 175°C. It is supplied in a through-hole DO-204AL (DO-41) axial leaded package. Environmental compliance is claimed as RoHS3 compliant, REACH unaffected, and halogen free, though these are unverified.
