Automotive-grade transient suppression for harsh environments
The 1.5KE12CAH: The 94 A peak pulse current means it can sink substantial surge energy from inductive load dumps or ESD strikes without failing short. The breakdown voltage min is 11.4 V, so the protection window starts just above the 10.2 V standoff — tight enough to protect 12 V nominal rails without nuisance triggering on normal ripple.
Through-hole DO-201 package — board-fit and rework considerations
Supplied in a DO-201AA (DO-27) axial-lead package with through-hole mounting. The DO-201 body is larger than the smaller DO-41 or SMA packages, so the hole diameter and pad spacing on the PCB must match the lead diameter and body length — check the mechanical drawing before layout. Shipped in Tape & Reel — the axial leads are taped per EIA-296, so it feeds through standard radial insertion machines. No MSL concern for a through-hole part, but the leads should be solderable within 12 months of manufacture if stored in a dry environment.
No power-line protection — signal and data bus application
The spec explicitly notes Power Line Protection: No. This TVS is designed for signal, data, or low-power DC buses — not for AC mains or high-current power inputs. Use it on CAN, LIN, sensor outputs, or 12 V control rails where the transient energy stays within the 1500 W rating.
