The 190 V minimum breakdown voltage provides a 19 V margin above the 171 V standoff, ensuring the TVS triggers before the protected rail exceeds its rating. ## Through-hole axial package for board-level protection Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE200A-/73 mounts through-hole — the leads handle the thermal pulse energy better than surface-mount equivalents for the same 1500 W rating. The single unidirectional channel clips positive transients above the breakdown threshold; for bidirectional protection on AC rails, two devices back-to-back or a bidirectional variant is needed.","metaTitle":"Vishay 1.5KE200A-E3/73 TransZorb TVS, 1500W, 274V Clamp","metaDescription":"Vishay 1.5KE200A-E3/73 TransZorb Zener TVS diode, 1500W peak pulse, 274V clamping at 5.5A.
