No power line protection here; this is a signal- or low-power-rail suppressor. ## DO-201 axial — the scorch-mark tells you Housed in a DO-201AA (DO-27) axial-lead through-hole package, supplier device package DO-201. The axial body and 0.96 mm lead diameter are standard for this power class — the leads carry the surge current into the die without fusing open on a single 1500W pulse. On a repair bench, a shorted TVS in this package shows a characteristic blister on the body — the scorch mark tells you which part actually died. Replacement is a straightforward desolder-and-reseat job; the axial leads tolerate a few rework cycles before the solder joint at the PCB hole fatigues. ## Active lifecycle, wide temperature range Because it's active and in a standard DO-201 package, sourcing is straightforward through independent distribution.","metaTitle":"1.5KE9.1CA A0G Taiwan Semiconductor TVS, 1500W, 13.4V Clamp","metaDescription":"1.5KE9.1CA A0G bidirectional Zener TVS, 1500W peak pulse, 13.4V clamping, DO-201 axial.
