The bidirectional configuration means a single device protects both polarities — useful on AC lines or floating DC buses where polarity reversal is possible. ## DO-201 axial package and mounting Housed in a DO-201AA / DO-27 axial-lead package (supplier device package DO-201), the 1.5KE400CA is a through-hole part. The axial leads suit point-to-point wiring, terminal blocks, or PCB through-holes with standard 0.040-inch diameter holes. The junction operates from -55°C to 175°C, covering industrial and some automotive under-hood environments.","metaTitle":"1.5KE400CA Littelfuse TVS Diode, 1500W, 548V Clamp, DO-201","metaDescription":"Littelfuse 1.5KE400CA bidirectional TVS diode, 1500W peak pulse, 342V standoff, 548V clamp.
