The 1.5KE47ARL4G: The 40.2 V reverse standoff voltage means the protected rail can run at 40 V nominal without the diode leaking or conducting in standby — the breakdown starts at 44.7 V minimum. The DO-201AD axial-lead package handles the 1.5 kW surge without the thermal limitations of a smaller body — the lead diameter and glass-passivated junction are sized for repetitive surge events in industrial power supplies, motor drives, and telecom rectifiers.
Temperature range and physical fit
Operating junction temperature spans -65°C to 175°C — wide enough for outdoor telecom cabinets, engine-bay electronics, or high-temp industrial enclosures where the ambient inside the box exceeds 85°C. Through-hole axial mounting in DO-201AD — the leads insert into plated through-holes on the PCB and are wave-soldered. The 0.052-inch lead diameter mates with standard 1.0 mm (0.040-inch) finished hole sizes; the body length is about 9.5 mm, so it fits between adjacent rows on a 0.100-inch pitch grid. The reel quantity is typically 1200 or 1400 pieces depending on the reel diameter; confirm the exact count at quote time.
