1500 W peak pulse, 698 V clamp — TVS for 434 V rails
The 1.5KE510A-E3/73: The 434 V standoff means this diode sits across a DC bus or signal line up to that voltage without conducting leakage current. When a transient exceeds 485 V, the Zener avalanche clamps the spike to 698 V, protecting downstream silicon rated for the 700 V class.
DO-201AA axial — through-hole board integration
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE510A-/73 mounts through-hole. The axial body suits point-to-point wiring or PCB insertion where the lead bend radius and hole diameter follow the package drawing.
Active production — sourcing posture
The 1.5KE510A-/73 carries an active lifecycle status from Vishay. Sourced through independent distribution channels.
