The 1500 W rating is derated linearly above 25°C; at 175°C the peak pulse capability drops to roughly 25% of the 25°C value, so thermal margin matters in high-ambient designs. ## DO-201 axial package and through-hole mounting Housed in the DO-201AA (DO-27) axial-lead package, the 1.5KE9.1CA B0G is a through-hole part suited for point-to-point wiring, terminal blocks, or PCB mounting with 0.040-inch diameter leads. The axial form factor allows it to be soldered directly into a board or wired as a free-hanging component in a panel harness. Supplied in bulk packaging, it is a practical choice for manual assembly or low-volume production runs where tape-and-reel feed is unnecessary. ## Active production — sourcing posture The part carries no known PCN activity; date codes are fresh production.","metaTitle":"1.5KE9.1CA B0G TVS Diode, 1500W, 7.78V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE9.1CA B0G bidirectional TVS, 1500W peak pulse, 7.78V standoff, 13.4V clamp.
