The 15.6 V clamp limits the voltage seen by the protected IC during a surge — a 12 V-rated capacitor or regulator sees a transient clamped 3.6 V above its rail, well within typical 20% margin. Peak pulse current of 100 A at the 10/1000 µs waveform means the diode can absorb a direct lightning-induced surge on a cable entry or an inductive load dump without failing short. The 1500 W peak pulse power is the energy-handling ceiling for a single pulse; repetitive events require derating per the manufacturer's pulse derating curve.","metaTitle":"1.5KE11A A0G TVS Diode, 1500W, 9.4V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE11A A0G Zener TVS diode, 1500W peak pulse, 9.4V standoff, 15.6V clamp, DO-201AA axial.
