Breakdown starts at 396 V min, so the device begins to clamp just above the 356 V working level. Bidirectional (single channel) — both polarities are clamped symmetrically. ## TransZorb® series identity This is part of Vishay's TransZorb® series, a well-known TVS diode family designed for general-purpose circuit protection.","metaTitle":"1.5KE440C-E3/54 Vishay TVS, 1500W Bidirectional, DO-201AA","metaDescription":"Obsolete 1.5KE440C-E3/54 Vishay TransZorb® bidirectional TVS diode, 1500W peak pulse, 356V standoff, DO-201AA.
