For a 24 V rail, the 27.7 V clamp sits well below typical semiconductor breakdown thresholds, providing a clean crowbar action. ## Through-hole DO-201 package — board-fit and temperature range Housed in a DO-201AA (DO-27) axial leaded package, the device mounts through-hole with a 0.9 mm lead diameter — compatible with standard 1.0 mm PCB holes. The DO-201 footprint is common across the 1.5KE family, so a single board layout serves multiple voltage variants. No power line protection is built in — this is a unidirectional transient suppressor for signal or low-voltage DC rails. ## Active production — sourcing and compliance The part is supplied in Tape & Box (TB) packaging, suitable for hand-insertion or selective soldering.","metaTitle":"Comchip 1.5KE20A-HF TVS Diode, 1500W, 17.1V Standoff","metaDescription":"Comchip Technology 1.5KE20A-HF Zener TVS diode, 1500W peak pulse power, 17.1V reverse standoff, 27.7V clamping.
