A downstream DC-DC converter with a 250 V abs-max input would be stressed beyond its rating; the designer must ensure the converter's avalanche rating or an upstream filter absorbs the residual. No power-line protection flag means this device is not rated for mains AC transient suppression per IEC 61643-11 — it is a DC-rail TVS, not a varistor or MOV replacement for 230 VAC inputs. ## Package and Assembly — Through-Hole DO-201AA in a Surface-Mount World The DO-201AA (DO-27) axial-lead package with through-hole mounting suits wave-solder or hand-solder assembly. The 0.042-inch lead diameter fits standard 1.0 mm PCB holes; the body length of about 7.6 mm and lead spacing of 8.9 mm require a through-hole footprint with adequate annular ring for thermal relief. Operating junction temperature from -55 °C to 175 °C covers engine-bay ambient and exhaust-adjacent locations where standard 150 °C TVS would derate. The AEC-Q101 qualification adds stress-tested reliability screening (H3TRB, temperature cycling, ESD) required for PPAP submission in automotive Tier-1 programs.","metaTitle":"1.5KE200AHE3_A/C Vishay TVS Diode, 1500W, 274V Clamp","metaDescription":"Active Vishay 1.5KE200AHE3_A/C automotive TVS, 1500W peak pulse, 274V clamp at 5.5A, AEC-Q101, -55 to 175°C.
