What the 1500W peak pulse rating means for your board
The 1.5KE160CA-T: The clamping voltage hits 219V at the peak current of 6.8A, so the protected rail sees no more than 219V across the transient. Reverse standoff is 136V typ — the diode stays off below that, drawing negligible leakage. Breakdown starts at 152V min, meaning the TVS begins conducting before the rail exceeds the standoff by about 12%.
Through-hole axial DO-201AA / DO-27 body — the leads are 0.042-inch diameter tin-plated copper. The part sits upright or lays flat; the hole spacing on the PCB should match the lead centre distance of 0.375 inch (9.5 mm) typical for the DO-201 outline. Solder joint inspection is straightforward — the lead exits the body and the fillet wets the barrel. No MSL rating applies to through-hole parts — no bake required before reflow.
