P4KE8.2A Description

Short technical summary and product information.

The Littelfuse P4KE8.2A is a 400W unidirectional Zener TVS diode designed for protection of sensitive electronic equipment from voltage transients. It offers a maximum clamping voltage of 12.1V and can handle peak pulse currents up to 33.9A under a 10/1000μs waveform. The device features an ultra-fast response time typically less than 1.0ps, making it suitable for EFT, ESD, and induced lightning transient protection. It is IEC 61000-4-2 compliant with ESD ratings of 30kV air and 30kV contact. The P4KE8.2A is housed in a through-hole DO-204AL (DO-41) axial leaded package, with a junction temperature range of -55°C to 175°C. Typical thermal resistance is 60°C/W junction-to-lead and 100°C/W junction-to-ambient. The diode is RoHS compliant, halogen-free, and lead-free (E3). Applications include I/O interfaces, VCC bus, telecom, computer, industrial ICT, and consumer electronics.
