AEC-Q101 is the automotive discrete semiconductor qualification standard. The Automotive grade flag means this TVS is intended for under-hood or chassis-domain electronic modules where the ambient temperature and vibration profile exceed industrial limits. The 34 A peak pulse current at the clamping voltage gives the system designer a direct number for fuse coordination and PCB trace width budgeting. Power line protection is not supported — this is a unidirectional device for signal or DC rail clamping, not AC mains. ## Through-hole DO-201AA axial package — board integration The DO-201AA (DO-27) axial-lead package is a through-hole form factor that mounts into plated through-holes on a PCB or terminal block. The axial leads handle the thermal cycling of the junction during repeated surge events better than a surface-mount package of equivalent power rating, because the lead frame conducts heat into the board copper and the air around the body.","metaTitle":"1.5KE33AHB0G TVS Diode, 28.2V Standoff, 1500W, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE33AHB0G Zener TVS, 28.2V reverse standoff, 45.7V clamp, 34A peak pulse, AEC-Q101 automotive grade.
