154 V standoff, 246 V clamp — where this TVS fits
The 1.5KE180A B0G: Its 154 V reverse standoff voltage means the protected line sees no leakage at normal operating levels up to that rail; once the transient exceeds 171 V breakdown minimum, the device clamps at 246 V maximum while shunting 6.4 A peak pulse current to ground. The 1500 W rating at the standard telecom waveform gives margin for secondary lightning or inductive kickback events in industrial control and power supply circuits.
Through-hole DO-201 — board integration
Housed in a DO-201AA / DO-27 axial leaded package (supplier device package DO-201), the part mounts through-hole on a PCB or terminal strip. The axial body sits above the board — lead spacing and hole diameter follow the standard DO-201 footprint, which is shared across the 1.5KE family.
Active production — sourcing posture
Taiwan Semiconductor lists the 1.5KE180A B0G as Active.
