The P6KE51A-T: The DO-15 axial package (DO-204AC) is a standard through-hole footprint — the body diameter is roughly 3.6 mm and the lead spacing suits 0.3-inch (7.62 mm) pitch on a perforated board. The axial leads are tin-plated copper, compatible with wave-solder assembly. This is a unidirectional device (single TVS channel) with no power-line protection feature — it clamps transients in one polarity and is intended for DC rail or signal-line protection where the reverse standoff voltage matches the operating rail.
