Zener TVS diode, 1500 W peak pulse, DO-201 axial
The 1.5KE51A-T: The DO-201 axial package (also known as DO-27) is a through-hole form factor that suits high-reliability point-to-point wiring or PCB mounting where the lead spacing matches the existing layout — the two axial leads carry the full surge current through the junction.
Temperature range and operating environment
Rated for continuous junction operation from -55 °C to 175 °C, the part covers the full industrial temperature envelope and extends into the high end for power-converter or motor-drive environments where the ambient near the suppression device runs hot. No power line protection rating — the device is intended for general-purpose transient suppression on signal, data, or low-voltage DC rails where the standoff voltage matches the nominal rail.
Sourcing reality — obsolete, available through independent channels
Availability and pricing are quoted per lot against the BOM quantity — no stock-holding claim, no deferred manufacturer channel. The base product number 1.5KE51 covers the family; the -T suffix indicates Tape & Reel packaging. Parts on cut tape or full reels are both available through the spot market depending on the lot.
