Protection window and what the clamping voltage means for your rail
The 1.5KE62CAHE3_A/D: Breakdown starts at 58.9V minimum, and the clamping voltage caps at 85V at the full 17.6A pulse. That 85V ceiling is the key number: your downstream components (DC-DC converters, sensors, ECUs) must survive at least 85V for the pulse duration. The bidirectional configuration (single channel) means one device protects both positive and negative transients — useful on signal lines like CAN bus, LIN, or sensor outputs where polarity isn't fixed.
Through-hole axial package — hand-solderable and breadboard-friendly
Housed in a DO-201AA (DO-27) axial leaded package, this is a through-hole part — easy to hand-solder, breadboard, or retrofit into existing PCB layouts.
