The 14.5 V reverse standoff voltage is the maximum DC or peak-AC voltage the TVS can withstand without significant leakage — design the protected line to stay at or below this value. Housed in the DO-201AA (DO-27) axial-lead package, it supports through-hole mounting with a 1.5KE supplier device package code. ## Obsolete — sourcing through independent channels For existing BOM lines or repair stock, the device is available through independent surplus and broker channels.","metaTitle":"Vishay 1.5KE18C-E3/73 TVS, 1.5kW, 26.5V Clamp, DO-201AA","metaDescription":"Obsolete Vishay 1.5KE18C-E3/73 TransZorb® bidirectional TVS, 1500W peak pulse, 26.5V clamping, DO-201AA axial lead.
