The 70.1V clamping ceiling ensures the downstream components see a peak voltage well below typical 60V or 75V MOSFET breakdown thresholds. The 22A peak pulse current rating at the 10/1000µs waveform gives the designer a direct input for the surge energy calculation: 1500W peak at 70.1V clamping. The bidirectional configuration (single channel) protects both polarities with one device, saving board space and reducing part count on AC-coupled or bipolar rails. ## Package and board integration Housed in a DO-201AA (DO-27) axial leaded package with a DO-201 supplier device code, this diode is a through-hole part intended for point-to-point wiring, terminal blocks, or PCB mounting with 0.100-inch pitch holes. The axial body handles the thermal pulse of a 1500W surge without requiring a heatsink — the lead frame and solder joint are the primary heat path into the board copper.","metaTitle":"1.5KE51CA B0G TVS Diode, 1500W, 43.6V Standoff, DO-201","metaDescription":"1.5KE51CA B0G bidirectional Zener TVS diode, 1500W peak pulse power, 43.6V standoff, 70.1V clamping, DO-201 axial.
