The 1.5KE body diameter is about 5.3mm, and the leads are 0.96mm diameter tinned copper, fitting standard 1.0mm PCB holes. The axial form factor means it mounts standing up or lying flat, depending on your board clearance. For a rework tech replacing one on a crowded board, the leads are long enough to lift and snip without pulling the pad. ## Lifecycle reality — obsolete, no direct successor Vishay has marked the 1.5KE56HE3/54 as obsolete. For a BOM that already uses this axial part, the only sourcing path is through independent surplus or broker channels. We can quote against your quantity and confirm availability at RFQ time — no stock-holding claim, but we can hunt lots with traceability.","metaTitle":"Vishay 1.5KE56HE3/54 TVS Diode, 1500W, DO-201AA Axial","metaDescription":"Obsolete Vishay 1.5KE56HE3/54 Zener TVS diode, 1500W peak pulse, AEC-Q101 automotive grade, 45.4V standoff, 80.5V clamp.
