TVS diode for 111 V rail protection — 1500 W peak pulse, 179 V clamp
The 1.5KE130CA-T: The 124 V minimum breakdown voltage ensures it stays off during normal operation, only conducting when a surge exceeds that threshold. This is a through-hole part in the DO-201AA / DO-27 axial package (supplier device package DO-201), suited for point-of-entry surge protection on power supplies, industrial controls, and general-purpose DC buses. The 1500 W rating covers moderate-energy transients — lightning-induced surges on outdoor cabling or inductive load dumps in a 24 V or 48 V system.
Obsolete — sourcing through independent channels
Diodes Incorporated lists the 1.5KE130CA-T as obsolete. For existing BOM lines, availability is through independent surplus and broker channels — each lot is date-code and marking verified before shipment.
Temperature range and package integration
The axial DO-201 package demands a through-hole PCB footprint with adequate pad area for solder fillet formation and heat sinking during the 10/1000 µs pulse. The tape-and-reel packaging (TR suffix) is intended for automated insertion — the axial leads are taped per EIA-296 standards. For manual or low-volume assembly, loose tubes or cut-tape are also available on request.
