Tape & Reel (TR) packaging supports automated insertion, while the axial leads allow manual or wave-solder assembly in prototype and low-volume builds.","metaTitle":"1.5KE91AHE3_B/C Vishay TVS, 1500W, 77.8V Standoff","metaDescription":"Vishay 1.5KE91AHE3_B/C TransZorb TVS, 1500W peak pulse, 77.8V standoff, AEC-Q101 automotive grade.
