The tape-and-box packaging (TB suffix) delivers the diodes in ammo-pack format for axial insertion machines; each reel holds 1400 pieces per the standard 1.5KE series packaging quantity. ## AEC-Q101 qualification and compliance The 'HE3' suffix denotes AEC-Q101 automotive qualification — the part has passed the full suite of stress tests (temperature cycling, HTRB, autoclave, solder heat resistance) required for Tier-1 automotive PPAP submissions.","metaTitle":"Vishay 1.5KE12AHE3_A/D TVS Diode, 1500W, 10.2V, DO-201AA","metaDescription":"Vishay 1.5KE12AHE3_A/D automotive AEC-Q101 TransZorb TVS, 1500W peak pulse, 10.2V reverse standoff, DO-201AA axial.
