The 1.5KE440CA-TP is a 1500W bidirectional TVS diode from Micro Commercial Co, designed to clamp transients on AC or DC lines where the normal operating voltage sits at 376V or below. This 376V standoff / 602V clamp window is sized for 400V-class power buses, three-phase rectified DC rails, or industrial equipment where the nominal line voltage is 277VAC or 380VDC and the transient protection must absorb a 1500W 8/20µs or 10/1000µs surge without letting the spike exceed 602V.
Package and board integration for the DO-201AE axial
Housed in a DO-201AE axial-lead package, the 1.5KE440CA-TP is a through-hole device intended for point-of-entry surge protection on a PCB or terminal block. The axial body handles the thermal pulse of a 1500W transient without cracking the epoxy case, and the lead spacing matches standard 0.4-inch or 10mm pitch on a terminal strip or PCB hole pattern. The base product number 1.5KE440 identifies the family; the CA suffix marks this as the bidirectional version, and the -TP suffix is Micro Commercial Co's packaging code for tape-and-reel delivery.
Active production and sourcing posture
No pin-compatible second source or official successor is listed; the 1.5KE440CA-TP is the standard order code for this voltage and package combination from Micro Commercial Co.
