For a BOM line that depends on this specific TransZorb bidirectional TVS, the procurement decision is immediate: secure lifetime-buy inventory now through independent distribution, or plan a redesign around an active successor. The 6.4A peak pulse current rating defines the surge it can absorb before the junction exceeds the 175°C maximum operating temperature. ## Clamping voltage and pulse-handling in a transient event The DO-201AA (DO-27) axial-lead package handles the thermal dissipation through the leads into the PCB; mounting is through-hole, so the board's copper area and airflow set the effective derating at elevated ambient temperatures.","metaTitle":"Vishay 1.5KE170CA-E3/51 TransZorb TVS, 1500W, 234V Clamp","metaDescription":"Vishay 1.5KE170CA-E3/51 TransZorb bidirectional TVS diode, 1500W peak pulse, 234V clamp, DO-201AA.
