The reverse standoff (working voltage) is 47.8 V — the rail can sit at that level continuously without leakage becoming a problem. Supplied in a DO-201AA (DO-27) axial-lead package, through-hole mount. The DO-201 footprint is a standard axial diode hole pattern — two 1.0 mm diameter holes on 0.375-inch lead spacing. The tape-and-box packaging (TB) suits hand-insertion or selective-wave solder; no moisture sensitivity level concern for a hermetic glass-passivated die in an axial body. ## Active production — no lifecycle worry Comchip Technology lists the 1.5KE56A-G as Active.","metaTitle":"1.5KE56A-G Comchip TVS Diode, 1500W, 77V Clamp, DO-201","metaDescription":"1.5KE56A-G Zener TVS diode from Comchip Technology, 1500W peak pulse power, 77V clamping, DO-201AA axial package.
