The clamping voltage of 11.3 V at 139 A peak pulse current sets the maximum voltage the load experiences during a surge — this is the figure to compare against the downstream component's absolute maximum ratings. With no power-line protection feature, this TVS is intended for signal lines, low-power supply rails, or I/O ports — not for mains or high-energy AC inputs. The single unidirectional channel protects one polarity; for bidirectional or AC-coupled lines, two devices in series-opposed configuration are needed. ## DO-201AA axial through-hole package The DO-201AA (also known as DO-27) axial leaded package allows through-hole mounting with the body standing off the board. The large copper lead frame and body geometry dissipate the heat from repetitive pulse events better than a surface-mount equivalent — important for applications where the TVS absorbs multiple transients over the product life. Supplied in bulk packaging, this variant is suited for hand-assembly or low-volume production runs where tape-and-reel is not required. The through-hole form factor also simplifies rework and field replacement compared to a soldered SMD part. ## Active production — no obsolescence risk The AEC-Q101 certification means each device has passed the reliability stress tests (temperature cycling, HAST, autoclave, solder heat resistance) required for automotive tier-1 approval.","metaTitle":"1.5KE7.5AHB0G Taiwan Semi Zener TVS, 1500W, DO-201","metaDescription":"1.5KE7.5AHB0G Zener TVS diode, 1500W peak pulse, 6.4V standoff, AEC-Q101 automotive, DO-201AA axial.
