Clamping is specified at 113 V maximum at the 13.5 A peak pulse current — this is the voltage the protected IC sees during the surge, so the downstream device must have an absolute-max rating above 113 V for the protection to hold. ## Package and board integration Housed in the DO-214AA (SMB) package, the 1.5SMB82A is a surface-mount device with a standard JEDEC footprint — the same pad layout used for SMBJ-series parts, so no board respin if swapping between equivalent TVS diodes from different lines. Supplied on Tape & Reel, consistent with automated pick-and-place assembly for high-volume telecom line cards.","metaTitle":"1.5SMB82A Littelfuse Zener TVS, 1500W, DO-214AA","metaDescription":"Littelfuse 1.5SMB82A Zener TVS diode, 1500W peak pulse power, 70.1V standoff, DO-214AA SMB.
