Product details

Transient suppression for 214V signal rails

The 1.5KE250CA-B is a 1500W bidirectional TVS diode from Diodes Incorporated, designed to clamp transients on DC rails and signal lines with a nominal operating voltage up to 214V. The single bidirectional channel means it protects both polarities in one package — useful for AC-coupled or floating signal pairs where a unidirectional part would require two devices back-to-back.

Obsolete — sourcing through independent channels

Diodes Incorporated has marked the 1.5KE250CA-B as Obsolete.

Housed in a DO-201AA / DO-27 axial-lead package, the 1.5KE250CA-B is a through-hole device that solders into a 0.040-inch (1.0 mm) hole on the PCB.
