Unidirectional (single-channel) construction clamps only one polarity — the forward drop handles the reverse surge. The 7.13V minimum breakdown voltage guarantees the avalanche threshold is reached before the protected circuit's own breakdown. ## Package and board-fit for through-hole designs DO-201AA (DO-27) axial package — the 1.5KE body diameter and lead spacing match standard through-hole layouts for telecom line cards and automotive ECU protection stages. Tape-and-reel packaging supports automated insertion; the axial leads are tinned for solderability in wave or selective soldering profiles.","metaTitle":"Vishay 1.5KE7.5AHE3_B/C TransZorb TVS, 1500W, AEC-Q101","metaDescription":"Vishay 1.5KE7.5AHE3_B/C automotive-grade Zener TVS diode, 1500W peak pulse, 6.4V standoff, 11.3V clamp, DO-201AA.
