Protection window and operating range
The 1.5KE220CA-E3/54: The single bidirectional channel protects symmetrical signal pairs or AC lines with one device, eliminating the need for two series-connected unidirectional diodes.
Package and board integration
Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE220CA-/54 mounts into a 1.1 mm diameter hole on a standard PCB or terminal strip — the lead bend radius must stay above 2 mm to avoid cracking the glass passivation. Available in Tape & Reel (TR) and Cut Tape (CT) packaging options, which exact ordering code suits the pick-and-place or hand-insertion process on the line.
