The 1.5KE150-B: The clamping voltage at peak pulse current (7.3A) is 217.35V max, which sets the voltage stress the downstream components must survive. The DO-201AA axial-lead package (also known as DO-27) is through-hole mounted, so it fits legacy board layouts and high-reliability designs where a soldered joint beats a surface-mount pad for vibration resistance.
