The single bidirectional channel protects a single signal or power rail against both positive and negative transients, eliminating the need for two unidirectional devices in anti-series. ## Obsolete — sourcing through independent channels Vishay lists the 1.5KE13C-/73 as Obsolete. The 1500 W peak pulse rating and bidirectional configuration are the fit criteria to confirm against the original design.","metaTitle":"Vishay 1.5KE13C-E3/73 TransZorb TVS, 1500W, 10.5V Standoff","metaDescription":"Obsolete Vishay 1.5KE13C-E3/73 bidirectional Zener TVS diode, 1500W peak pulse, 10.5V reverse standoff, DO-201AA.
