That 23 V window between standoff and breakdown is the guard band for normal line ripple. Bidirectional — one channel handles both positive and negative going surges, so polarity doesn't matter when you solder it in. Useful on AC signal lines or DC rails where reverse transients are a risk. ## Package and rework — DO-201 axial is a through-hole friendly footprint DO-201AA (also known as DO-27) axial leaded package — the two wire leads come out opposite ends, so it sits flat on the board and the leads pass through plated holes. No hot-air rework needed; a standard soldering iron and desoldering wick or a solder sucker lifts it cleanly. The bulk packaging means you get loose parts, not tape-and-reel — fine for hand assembly or low-volume production.","metaTitle":"1.5KE250CA B0G TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE250CA B0G bidirectional TVS diode, 1500W peak pulse power, 214V standoff, DO-201 axial.
