Breakdown voltage min is 19V, so the device begins conducting between 19V and the clamp ceiling — this window protects downstream silicon rated for 30V or less. Automotive-grade qualification per AEC-Q101 means the 1.5KE20AH passed the full suite of stress tests: temperature cycling, high-temperature reverse bias (HTRB), and ESD robustness — required for PPAP submission on engine-control, body, or chassis modules. No power line protection (the part is a transient suppressor, not a rail clamp), so it is intended for unidirectional protection on DC buses, not AC mains. ## Active production, DO-201 axial leaded package The DO-201AA (DO-27) axial package is a through-hole form factor that mates with standard 0.036-inch diameter lead holes on a 2.54mm pitch grid.","metaTitle":"1.5KE20AH TVS Diode, 1500W, 17.1V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE20AH automotive TVS, 1500W peak pulse, 27.7V clamp, AEC-Q101, DO-201 axial.
