When a transient exceeds the 50V minimum breakdown voltage, the device clamps at 72.7V maximum while shunting 8.3A of peak pulse current. ## Bidirectional — no polarity concern on the board A single bidirectional channel means the SMBJ45CA-13-F clamps equally on positive and negative transients. This simplifies layout on AC-coupled signal lines or on power rails where reverse-polarity events are possible — no need to orient the cathode mark relative to the supply. The DO-214AA (SMB) package is a standard surface-mount footprint for 600W-class TVS diodes. ## Active production — no last-time-buy pressure The -13-F suffix indicates Tape & Reel packaging, the standard carrier for automated pick-and-place assembly. Cut Tape (CT) is also listed for prototype or low-volume builds. ## General-purpose application scope The SMBJ45CA-13-F is classified for General Purpose applications — no single end-market restriction. It fits power-supply input protection, DC bus clamping, telecom line cards, and industrial control I/O where a 45V rail needs transient suppression to IEC 61000-4-5 levels within the 600W peak-pulse envelope. This covers the full industrial temperature range and extends into military-grade cold — the device does not derate at low temperature, so the clamping voltage holds across the band.","metaTitle":"SMBJ45CA-13-F Diodes Inc TVS, 600W, 45V Bidirectional, SMB","metaDescription":"SMBJ45CA-13-F Zener TVS diode, 600W peak pulse, 45V reverse standoff, bidirectional, DO-214AA SMB.
