1.5KE550CA Bidirectional TVS Diode 550CA 550V 1.5KE550CA

The 1.5KE550CA is a 550V, 1500W bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse for protecting sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. Housed in a standard through-hole DO-201 axial leaded molded plastic package, this discrete component features a bidirectional configuration designed to safeguard high-voltage circuits and I/O interfaces. It operates with a minimum breakdown voltage of 522.5V and handles a peak pulse power dissipation of 1500W under standard 10/1000µs waveform conditions. Engineered with a maximum clamping voltage of 760V, fast response times, and low incremental surge resistance, this robust device delivers reliable performance across an operating junction temperature range from minus 55 to plus 175 degrees Celsius.
