Product details

1500W bidirectional TVS for 145V rails

The 1.5KE170CA-E3/73: Its 145V reverse standoff voltage protects 145V DC or 120V AC rails, clamping transients at 234V maximum before the 6.4A peak pulse current rating is reached. The Zener-type clamping mechanism triggers at a minimum breakdown of 162V, ensuring the protection threshold is well above the normal operating voltage but engages before the downstream components see damaging overvoltage.

Package and integration note

Housed in a DO-201AA (DO-27) axial leaded package, this through-hole device suits point-to-point wiring, terminal block assemblies, or PCB mounting with 0.050-inch diameter leads.
