For a 94 V bus, that clamp margin keeps downstream semiconductors inside their Vds or Vce ratings. ## Package and field swap Through-hole DO-201AA (DO-27 axial) package — the same footprint as the common 1.5KE series. Polarity is marked by the cathode band; orientation is obvious enough to get right with a multimeter check before soldering. No ESD bench needed for the swap, but the axial leads mean you want a steady hand and a clean iron tip to avoid cold joints on the board. ## Temperature range and general duty Listed for general-purpose applications; no power-line protection rating, so it is best suited for signal or DC rail transient suppression, not mains AC clamping.","metaTitle":"1.5KE110-B Littelfuse TVS Diode, 94V Standoff, DO-201","metaDescription":"Littelfuse 1.5KE110-B TVS diode, 94V reverse standoff, 1500W peak pulse, DO-201 axial.
