Surge protection for telecom lines
The 1.5SMB22A: The DO-214AA (SMB) package is a common surface-mount footprint for TVS diodes in this power class, compatible with standard reflow profiles. The -65°C to +150°C junction temperature range covers telecom outdoor cabinets and industrial enclosures where ambient heat and surge self-heating both factor into the thermal budget.
Active lifecycle and BOM fit
The Tape & Reel packaging (per the standard SMB carrier) suits automated pick-and-place assembly; store the reels dry per the moisture sensitivity level typical for this package class.
