1.5 kW bidirectional TVS for automotive transient protection
The 1.5KE200CAHB0G: It clamps transients to 274 V maximum at a peak pulse current of 5.7 A, protecting downstream electronics from load-dump, inductive kickback, and ESD events. 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.
