The reverse standoff voltage is 7.02 V typical, so the diode stays transparent below that line and only starts conducting when the transient pushes above it. Breakdown starts at 7.79 V minimum. ## Package and temperature envelope Housed in the DO-201AA (DO-27) axial-leaded through-hole package, the 1.5KE8.2A/54 is a hand-solderable or wave-solderable part — the axial leads insert into plated through-holes and the body stands off the board.","metaTitle":"Vishay 1.5KE8.2A/54 TransZorb TVS, 1500W, 12.1V Clamp","metaDescription":"Obsolete Vishay 1.5KE8.2A/54 unidirectional Zener TVS diode. 1500W peak pulse power, 12.1V clamping at 124A, DO-201AA axial.
