Because it is bidirectional, a single device protects both polarities on AC lines or bipolar DC rails — no need for two diodes back-to-back. The 45V standoff also covers 36V and 48V nominal rails with margin for steady-state tolerance. ## Package and board-fit — DO-214AA SMB The SMB body is larger than the SMA sibling, which means lower thermal resistance to the board copper for sustained pulse trains. ## Sourcing reality — active line, quoted per reel The base product number SMBJ45 covers the full voltage family, so the production line runs continuously for the whole SMBJ series. Supplied in Tape & Reel (TR) or Cut Tape (CT) — the reel quantity is the standard SMBJ reel count. For volume BOM positions, the per-unit cost lands below the cut-tape price break; quoted to order against the reel MOQ.","metaTitle":"SMBJ45CA-13 Diodes Inc Zener TVS, 45V, 600W, DO-214AA","metaDescription":"SMBJ45CA-13 bidirectional Zener TVS, 45V reverse standoff, 72.7V clamp at 8.3A, 600W peak pulse.
