  "abstract": "Tidal disruption event (TDE) progenitors are commonly modelled as single stars on parabolic orbits around a supermassive black hole (SMBH), yet observations reveal a richer diversity of dynamical pathways. We show that tidal separation of stellar binaries by a $10^6\\, \\mathrm{ M}_\\odot$ SMBH provides a natural mechanism for producing eccentric TDEs. Using restricted three-body and smoothed particle hydrodynamics (SPH) simulations, we model a solar-like star (SLS)–white dwarf (WD) binary on a parabolic orbit. The binary orbital phase governs the outcome: one component is captured on to a tightly bound orbit while the other is ejected as a hypervelocity object, naturally producing TDEs with eccentricities $e \\ne 1$. We classify these into elliptical TDEs and hyperbolic TDEs, occurring with equal probability. For ${\\sim} 88 {{\\ \\rm per\\ cent}}$ of orientations the disruption is clean, with no mass accreted by the WD. The remaining ${\\sim} 12 {{\\ \\rm per\\ cent}}$, in two narrow phase windows, leaves the WD with a captured debris envelope (WDDE). About a third of that, ${\\sim} 4 {{\\ \\rm per\\ cent}}$ of orientations, involves a direct WD–SLS collision near pericenter, with fallback peaking up to 5 times earlier and 20 times higher than for a single star; for the innermost ${\\sim} 1.5 {{\\ \\rm per\\ cent}}$ the total WDDE mass exceeds $1.4\\, \\mathrm{ M}_\\odot$, though the degenerate core does not, since the captured material forms a non-degenerate envelope, suggesting outcomes ranging from nova-like events to peculiar red giant-like objects. Depending on the phase, the mechanism may also produce repeating partial TDEs and quasi-periodic eruptions. Binary–SMBH encounters provide a robust channel for generating diverse TDEs with distinct observational signatures.",
