With a peak pulse current rating of 64.7 A, this part handles a direct lightning-induced transient or load-dump event on a 14 V automotive bus. Packaged in DO-214AA (SMB), a standard surface-mount footprint with a 0.050-inch (1.27 mm) pitch — the same pad layout as many SMB Schottky and Zener diodes, so a single PCB footprint can serve multiple BOM positions for different voltage variants.","metaTitle":"Bourns 1.5SMBJ14CA-H TVS Diode, 1500W, AEC-Q101, DO-214AA","metaDescription":"Bourns 1.5SMBJ14CA-H bidirectional TVS diode, 1500W peak pulse, 14V standoff, AEC-Q101 automotive grade.
