1500 W bidirectional clamp for 12 V automotive rails
The 1.5KE12CAHE3_A/D: It clamps transients from a 10.2 V reverse standoff voltage to a maximum of 16.7 V at 89.8 A peak pulse current.
Voltage clamping and pulse current — what the ratings mean for your rail
Breakdown starts at 11.4 V minimum, and the clamp holds at 16.7 V maximum under the full 89.8 A pulse. For a 12 V system, a 16.7 V clamp means the TVS absorbs the surge before the downstream regulator's abs-max rating is reached — provided the trace inductance and source impedance are within the application note limits.
Active production — sourcing for automotive BOMs
The DO-201AA axial through-hole package (also known as DO-27) is a standard footprint for TVS diodes in power distribution and ECU input protection.
