Housed in the DO-214AC (SMA) package, the SMAJ40CA-13 is a surface-mount device with a small footprint suitable for high-density PCB layouts. The SMA body is rated for the full 400 W pulse without requiring external heatsinking — the copper pad area under the cathode tab on the PCB sets the effective thermal impedance for repetitive pulse trains. Available in both Tape & Reel and Cut Tape options, the part is compatible with standard pick-and-place assembly. The -13 suffix indicates the reel packaging variant; the base product number is SMAJ40.","metaTitle":"SMAJ40CA-13 Diodes Inc TVS, 400W, 64.5V Clamp, DO-214AC","metaDescription":"SMAJ40CA-13 bidirectional TVS diode, 400W peak pulse power, 64.5V clamping, DO-214AC SMA.
