The DO-201AA axial through-hole package is straightforward to hand-rework — the leads are long enough to dress into a PCB or terminal block, and the body orientation is unambiguous. No special hot-air profile needed; a standard soldering iron with a chisel tip handles the joint. ## Clamping window and pulse rating Breakdown occurs at 14.3 V minimum, clamping at 21.2 V maximum when the 10/1000 µs waveform hits 74 A peak pulse current. The 12.8 V standoff means the diode stays transparent below that rail voltage — no leakage-induced quiescent draw on the battery. This is the same qualification tier used for under-hood and chassis-domain electronics.","metaTitle":"TSC 1.5KE15AH Automotive TVS, 1500W, DO-201AA","metaDescription":"Taiwan Semiconductor 1.5KE15AH Zener TVS diode, 1500W peak pulse, AEC-Q101 qualified, 12.8V standoff, DO-201AA axial.
