When a TVS fails short from an overstress event, the scorch mark on the board tells you this part absorbed the hit. The DO-201AA axial package is a through-hole footprint that survives rework well — you can pull the dead part and solder in a replacement without lifting pads. ## Obsolete — sourcing the 1.5KE24CHE3/73 today For a board that needs this exact TVS, the supply path runs through independent surplus and broker channels. No pin-compatible drop-in replacement is documented by Vishay, so a board spin would be required to move to a different TVS family. ## AEC-Q101 and the automotive temperature envelope For a 24 V truck or heavy-equipment rail, the 19.4 V standoff leaves margin above the nominal bus voltage. The 34.7 V clamp keeps the transient below the 40 V abs-max of many common automotive-grade buck converters and linear regulators.","metaTitle":"1.5KE24CHE3/73 Vishay TVS, 1.5kW, DO-201AA, Obsolete","metaDescription":"Vishay 1.5KE24CHE3/73 TransZorb TVS, 1500W peak pulse, 19.4V standoff, AEC-Q101, obsolete.
