600W bidirectional TVS for 154V rail protection
The P6KE180CA-B: A single bidirectional channel means one device protects both polarities on a signal or power rail — useful for AC-coupled lines or differential pairs where the clamping is symmetrical.
Clamping voltage and pulse current — what 2.4A Ipp means
At the 246V clamp, the device conducts 2.4A peak pulse current (10/1000µs). That 2.4A figure is the current the TVS shunts during the transient — it is not a continuous rating but the peak the junction handles before the energy dissipates. The 154V standoff is the maximum DC or peak-AC voltage the TVS blocks without conducting in normal operation. Above 171V the breakdown region starts; the device clamps hard at 246V to protect downstream silicon rated for that voltage ceiling.
Through-hole DO-15 axial package — board-fit note
Housed in a DO-204AC (DO-15) axial leaded package, supplied in bulk. The through-hole form factor suits point-to-point wiring, terminal blocks, or PCB layouts where the part is hand-inserted after wave solder. No power line protection feature — this is a signal or low-power rail clamp.
