Clamping and breakdown margins
The 1.5KE350CA-G: Breakdown occurs at a minimum of 332.5 V, giving a 33 V window between the standoff rail and the onset of conduction. The 3.11 A peak pulse current at the clamping voltage tells you the device handles a 1.5 kW surge into a 155-ohm source impedance — useful for estimating margin in a given surge environment. The bidirectional configuration means a single DO-201 part protects both polarities on the same line, saving a board position compared to back-to-back unidirectional diodes.
Through-hole axial package for rework
Housed in a DO-201AA (DO-27) axial leaded package, this part is a through-hole component. The axial body is straightforward to hand-solder or wave-solder, and if a replacement is needed, it lifts cleanly with a desoldering tool — no hot-air risk to adjacent components. The -55°C to 150°C junction temperature range covers industrial and telecom environments where the ambient sees wide swings and the device self-heats during a surge event.
