Bidirectional construction (one channel) protects against both positive and negative transients with a single through-hole part — no need to orient the cathode; it clamps equally in both directions. ## DO-201AA axial package and field-swap fit Housed in the DO-201AA (DO-27) axial-lead package, the 1.5KE11CA-/73 is a through-hole part that solders into a board or clips into a panel-mount holder — the axial leads make it a straightforward swap on site with a standard iron, no hot-air station needed.","metaTitle":"1.5KE11CA-E3/73 TransZorb TVS, 1.5kW, 9.4V Standoff","metaDescription":"Vishay 1.5KE11CA-E3/73 bidirectional TVS diode, 1500W peak pulse, 9.4V reverse standoff, DO-201AA axial.
