The 5.2A peak pulse current gives the designer a hard limit for fuse coordination or downstream component stress. Housed in a DO-214AC (SMA) package, this is a two-terminal surface-mount device with a cathode band on one end — orientation is obvious under magnification. The SMA body is small enough to rework with a standard hot-air station; the junction-to-ambient thermal path depends on the copper pad area under each terminal, so keep the footprint generous if the board sees repetitive surges. This is a current-production part, sourced to order against BOM quantities.","metaTitle":"SMAJ54CE3/TR13 TVS Diode – 54V Standoff, 500W, DO-214AC","metaDescription":"SMAJ54CE3/TR13 Zener TVS, 54V reverse standoff, 60V breakdown, 96.3V clamp at 5.2A. 500W peak pulse power.
