That 64.5V clamp is the voltage the protected circuit must survive; if your downstream components have a 60V absolute maximum, this TVS may not hold them safe on a high-energy surge. The device operates from -55°C to 150°C junction temperature, covering industrial and automotive ambient ranges. ## DO-214AC SMA footprint and board integration Housed in a DO-214AC (SMA) surface-mount package, the SMAJ40CA-13-F mates with a standard SMA footprint. The supplier device package is also designated SMA. Tape & Reel packaging (Cut Tape available) supports automated pick-and-place assembly.","metaTitle":"SMAJ40CA-13-F Diodes Inc TVS, 400W, 40V Bidirectional, SMA","metaDescription":"SMAJ40CA-13-F bidirectional TVS diode, 400W peak pulse power, 40V reverse standoff, 64.5V clamping.
