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.","metaTitle":"Vishay 1.5KE12CAHE3_A/D TVS Diode, 1500W, Bidirectional","metaDescription":"Vishay 1.5KE12CAHE3_A/D bidirectional Zener TVS diode, 1500W peak pulse power, 10.2V standoff, AEC-Q101 qualified.
