That 53.3V ceiling is what the protected downstream circuitry sees during a surge — a figure to check against the absolute-maximum ratings of the ICs on that rail. This is a signal-line protector, not a mains-power device — the spec explicitly notes no power line protection. ## DO-214AC SMA package — rework and board-fit Housed in the standard DO-214AC (SMA) surface-mount package, the SMAJ33CA-13-F uses the familiar JEDEC footprint with the cathode band as the polarity mark — though for a bidirectional device, orientation does not matter for the clamping function. The SMA body is small enough to fit under a hot-air nozzle without heating adjacent parts, and the solder pads are wide enough that a standard iron tip can touch up a joint if needed.","metaTitle":"SMAJ33CA-13-F Diodes Inc TVS, 400W, 33V Bidirectional, SMA","metaDescription":"SMAJ33CA-13-F Diodes Inc Zener TVS diode, 400W peak pulse, 33V reverse standoff, bidirectional, DO-214AC SMA.
