The DO-201AA (DO-27) axial-lead through-hole package suits point-to-point wiring on terminal blocks or perforated boards in power supplies and industrial controls. ## Clamping and temperature envelope The 98V clamping voltage at 15.3A peak pulse current defines the maximum voltage a protected circuit sees during a surge event. For a 48V nominal bus, this clamp margin is roughly 2× the operating voltage, typical for a TVS in this power class. The operating junction temperature range spans -55°C to +175°C, covering military-temperature applications. ## Sourcing an obsolete TransZorb® Vishay lists the 1.5KE68C-/73 as Obsolete. No official successor order code is recorded in the lifecycle data. For a BOM line that requires this exact clamping voltage and package, the procurement path is surplus or broker inventory. A buyer should verify date code and RoHS compliance (the part ships in Tape & Box) when sourcing outside the authorized channel.","metaTitle":"1.5KE68C-E3/73 Vishay TVS, 1.5kW, 55.1V Standoff","metaDescription":"Obsolete Vishay 1.5KE68C-E3/73 TransZorb® bidirectional TVS, 1.5kW peak pulse, 55.1V standoff, DO-201AA axial.
