Bidirectional, axial-lead, 175°C rated
The 1.5KE120C-E3/73: This single-channel bidirectional device fits through-hole mounting in a DO-201AA (DO-27) axial package, rated for continuous junction temperature from -55°C up to 175°C. The 1.5kW peak pulse rating suits it for general-purpose transient suppression on 120V DC or 120V AC peak rails where a bidirectional clamp is preferred.
Obsolete — sourcing through independent channels
Vishay has marked the 1.5KE120C-/73 as obsolete. No official successor part number is recorded. For new designs a functionally equivalent bidirectional TVS with a 97.2V standoff and 1.5kW rating should be selected from current Vishay or competitor portfolios.
