1500W unidirectional TVS in DO-214AB SMC
The 1.5SMC51A TR13 PBFREE: The operating temperature range of -65°C to 150°C covers cold-start and under-hood environments without derating.
Active lifecycle — sourcing posture
No pin-compatible second source is listed on the manufacturer's cross-reference, so the BOM line is single-sourced to this order code.
The SMC footprint is larger than the SMA/SMB siblings, which gives a lower junction-to-board thermal resistance — important when the part must absorb repetitive surges without exceeding the 150°C junction limit. Supplied in Tape & Reel (TR), it is compatible with standard pick-and-place processes. The Pb-free finish (PBFREE suffix) means no RoHS exemption is needed for the solder joint.
