Clamping performance and BOM fit
The 1.5KE180A_R2_00001: Its 154 V reverse standoff voltage means it stays transparent on a nominal 150 VDC rail, only clamping when a transient pushes the line above that threshold. Maximum clamping is 246 V at the 6.1 A peak pulse current — the voltage the diode forces the transient down to. For a 150 V rail, that clamp margin (154 V standoff to 246 V clamp) gives downstream components a defined voltage ceiling during a surge event. The breakdown voltage range starts at 171 V minimum, so the diode begins conducting before the rail reaches an overvoltage condition. Operating temperature spans -65°C to 175°C junction, covering most industrial and telecom ambient profiles without derating concerns.
Package and board integration
Housed in a DO-201AE axial-lead package, the 1.5KE180A_R2_00001 is a through-hole device. The axial body sits inline with the leads, so it mounts standing upright or laid flat against the board — the lead bend radius matters for stress relief in high-vibration environments. No power line protection feature is built in — this is a standalone transient suppressor, not a filtered or integrated protector.
