Breakdown starts at 17.1 V min, and clamping hardens at 25.2 V max under the full 59.5 A pulse, holding the transient below the downstream component's absolute maximum rating. The 1500 W peak pulse rating (10/1000 µs) is the standard TVS energy benchmark — at shorter pulses the diode absorbs higher peak power; at longer or repetitive surges, derate per the datasheet's pulse-width curve. The single unidirectional channel protects one polarity rail; for bipolar or AC lines, pair two devices back-to-back or select a bidirectional variant. The DO-201 axial body with tin-plated copper leads handles wave-solder or hand-solder assembly without special handling.","metaTitle":"1.5KE18A-E3/73 Vishay TVS, 1.5kW, 15.3V Standoff, DO-201","metaDescription":"Vishay 1.5KE18A-E3/73 TransZorb TVS diode, 1500W peak pulse, 15.3V reverse standoff, DO-201 axial.
