The 1.5KE540CA-B: The 2A peak pulse current rating defines the surge it can absorb without damage.
Housed in a DO-201AA / DO-27 axial leaded package (through-hole), the 1.5KE540CA-B mounts into a standard 0.100-inch pitch hole pattern. The bidirectional construction means a single device protects both polarities on a 460V DC or AC line — no need for series stacking.
