For a 1500 W part, the actual energy handling depends on the pulse duration — shorter transients allow higher peak current, but the 10/1000 µs waveform is the industry-standard benchmark for comparing TVS diodes. ## Through-hole DO-201 package and temperature range Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE510CA is a through-hole part suited for point-to-point wiring or PCB mounting with lead forming. The bidirectional configuration (single channel) means it clamps both polarities with one device — useful on AC signal lines or DC rails where reverse polarity is a risk.","metaTitle":"Littelfuse 1.5KE510CA TVS Diode, 1500W, Bidirectional","metaDescription":"Littelfuse 1.5KE510CA bidirectional TVS diode, 1500W peak pulse power, 434V standoff, 698V clamp.
