AEC-Q101 qualification places it in the automotive-grade tier — the part is screened for the -55°C to +150°C junction temperature range and the reliability stress tests required for under-hood and chassis-mounted electronics. ## Package and board-fit for the DO-214AA footprint No special handling beyond standard MSL precautions for a molded plastic package. ## Active lifecycle and how to source it For current pricing and lead time, submit an RFQ through this listing.","metaTitle":"Bourns 1.5SMBJ20CA-H TVS Diode, 1500W, 20V, DO-214AA","metaDescription":"Bourns 1.5SMBJ20CA-H bidirectional Zener TVS, 1500W peak pulse, 20V standoff, AEC-Q101 qualified.
