The DO-214AA (SMB) package is a standard surface-mount footprint shared across the 1.5SMB family, so the pad layout stays the same if you need to swap to a different voltage variant in the same series. The operating temperature range spans -65°C to 150°C junction, which covers outdoor telecom cabinets that see summer heat soak and winter cold starts without derating the surge capability. The base product number is 1.5SMB, and the 82CA suffix denotes the 82V bidirectional variant. When sourcing, confirm the reel quantity (tape and reel packaging) matches your pick-and-place setup — the DO-214AA carrier tape pitch is standard for SMB diodes.","metaTitle":"Littelfuse 1.5SMB82CA TVS Diode, 1500W, 70.1V Standoff","metaDescription":"Littelfuse 1.5SMB82CA bidirectional TVS diode, 1500W peak pulse power, 70.1V reverse standoff, 113V clamping.
