The 1.5KE62CA R0G: For a 48 V or 53 V DC rail, this clamp margin of roughly 32 V above the standoff voltage gives the downstream silicon enough headroom to survive without avalanche breakdown. A shorter pulse (e.g. 8/20 µs) allows higher peak current; the datasheet derating curve governs the actual capability at elevated ambient temperatures. With a single bidirectional channel, this device clamps both polarities symmetrically — useful on AC signal lines or DC rails where the polarity is not fixed relative to ground.
DO-201 axial package and temperature range
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE62CA R0G is a through-hole device suited for point-to-point wiring or PCB mounting with lead forming. The supplier device package is DO-201; the axial leads are tin-plated copper, compatible with standard wave-solder profiles. No power line protection is claimed — this is a secondary-side transient suppressor, not a primary mains protector.
