This part carries AEC-Q101 automotive qualification, meaning it is screened for reliability under the temperature and vibration profiles typical of engine-bay and chassis-mounted modules. The operating junction temperature range spans -55°C to 175°C, covering cold crank and under-hood heat soak. ## Breakdown and standoff voltages — fit for 171 V nominal rails The reverse standoff voltage is 171 V (typ), so the diode does not conduct at normal operating levels on a 170 V DC bus or a 120 V AC line. The minimum breakdown voltage is 190 V, providing a guard band before the avalanche region. For a nominal 170 V rail, this TVS stays off until a transient pushes the line above 190 V. ## DO-201AA axial package — through-hole board fit Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE200CAHB0G mounts through hole. The axial body suits point-to-point wiring or PCB mounting where the leads can be formed to the board. Bulk packaging means the parts ship loose, not taped and reeled — a factor for pick-and-place if automated insertion is planned.","metaTitle":"1.5KE200CAHB0G TVS diode, 1.5 kW, 274 V clamp, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE200CAHB0G bidirectional TVS, 1.5 kW peak pulse, 274 V clamp, AEC-Q101 automotive.
