The signatures of heavy fermionic isotriplets () are probed through their direct production and subsequent decay at high energy electron–positron colliders. Unlike the case of LHC, the production process has strong dependence on the mixing of with electron (), making the leptonic collider unique to fingerprint the presence of such mixing. We establish that pair production considered at TeV can be employed to study both the cases of and of with fb luminosity, while the single production can probe the latter case with a few inverse femto barn luminosity at TeV. Exploring the mass reach, both the single and pair productions are capable of probing of mass close to the kinematic limits through selected channels. Investigating simultaneous limits on the parameter space, we identify suitable final states and their reach on and at 300 (100) fb luminosity in the case of pair (single) production.
