No official Vishay successor is recorded for this part, so a board-level redesign to a current-generation TVS may be the longer-term fix. ## 1.5 kW bidirectional clamp — the numbers that matter The reverse standoff voltage is 175 V — the rail it protects should stay below that in normal operation. Breakdown starts at 198 V minimum, and the clamping voltage at peak pulse current (4.4 A) is 344 V maximum. The 344 V clamp figure is the voltage the load sees during a surge event. For a 175 V DC bus or a 120 VAC rectified rail, that clamp gives enough margin to keep downstream semiconductors out of avalanche, provided their V(BR) rating clears 344 V. ## DO-201AA axial — board-fit and temperature range That covers the full industrial temperature range and extends into hot environments like power supplies near transformers or motor drives in enclosures with limited airflow.","metaTitle":"1.5KE220C-E3/73 Vishay TransZorb TVS, 1.5kW, 175V","metaDescription":"Vishay 1.5KE220C-E3/73 TransZorb bidirectional TVS, 1500W peak pulse, 175V standoff, 344V clamp.

A functional replacement would require a TVS with the same DO-201AA footprint, 175 V standoff, and 1500 W peak pulse rating — but the exact order code is unique. A board redesign to a current Vishay or Littelfuse part is the recommended path for new builds."},{"question":"What compliance documentation does Vishay provide for 1.5KE220C-/73?","answer":"The part is a Vishay TransZorb TVS in the 1.5KE series. Vishay typically provides RoHS and REACH compliance declarations for this product family.
