No power line protection (it's a standalone TVS, not a filtered suppressor), so it pairs with a fuse or PTC for overcurrent coordination. ## Sourcing posture — Last Buy status Vishay lists this part as Last Buy — meaning the manufacturer has announced end-of-life but still accepts final orders within a defined window. For BOM lines that already carry this MPN, the path is to source remaining inventory through independent distribution. Availability is lot-specific and confirmed at quote time against the required quantity.","metaTitle":"Vishay 1.5KE350A-E3/51 TransZorb TVS, 1500W, 300V Standoff","metaDescription":"Vishay 1.5KE350A-E3/51 Zener TVS diode, 1500W peak pulse, 300V standoff, 482V clamp.
