That 89 V window between standoff and clamp gives the designer margin to select a downstream DC-DC converter or linear regulator rated for the clamp ceiling. The single bidirectional channel means one device clamps both polarities — no need for two diodes in anti-series. The 175°C TJ ceiling is the absolute limit; derate the peak pulse power above 25°C per the datasheet curve. ## Obsolete — sourcing through independent channels Diodes Incorporated lists the 1.5KE170CA-T as obsolete. No pin-compatible direct replacement from Diodes is documented; a parametric search for a 1500 W bidirectional TVS in DO-201 with a 145 V standoff will identify functionally equivalent alternatives from other brands, but a board respin is not required if the package and footprint match.","metaTitle":"Diodes Inc 1.5KE170CA-T TVS Diode, 1500W, 234V Clamp","metaDescription":"1.5KE170CA-T bidirectional TVS diode, 1500W peak pulse power, 234V clamping.
