Product details

1.5 kW peak pulse, 256 V standoff — TVS for high-voltage DC rails

The 1.5KE300: Its 256 V reverse standoff voltage and 434.7 V clamping point make it a fit for protecting 240 VDC bus lines or high-voltage telecom supplies from transients up to 3.7 A peak pulse current. The DO-201AA axial-lead package (DO-27) mounts through-hole, suited for point-of-entry protection on a PCB or terminal block.
