The single bidirectional channel clamps both positive and negative overvoltage events symmetrically, which suits AC-coupled or floating lines where polarity is not fixed. The 15.6 V clamp voltage at 100 A means a 12 V rail sees the transient held under 16 V even at the full rated surge current — well within the absolute maximum of most downstream 16 V-rated DC-DC converters and linear regulators. Breakdown occurs at a minimum of 10.5 V, so the device remains transparent below that level and does not leak appreciably at the 9.4 V standoff voltage. The 1500 W peak pulse rating (10/1000 µs) is the energy the die absorbs in a single event — for repetitive surges, derate per the manufacturer's pulse derating curve, which typically halves the peak power at 175 °C junction. ## Through-hole axial package for board-level transient protection Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE11CA A0G mounts into a 1.1 mm diameter drilled hole on a standard PCB and is wave-solderable alongside other through-hole components. The DO-201 body handles the 1500 W pulse without cracking the encapsulation — the lead frame and die bond are sized for the surge current path, not just steady-state dissipation.","metaTitle":"1.5KE11CA A0G TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE11CA A0G bidirectional Zener TVS, 1500W peak pulse, 9.4V standoff, 15.6V clamp.
