It clamps transients at 29.2V max when conducting 51.4A peak pulse current, protecting downstream circuitry on 18V nominal rails. The DO-214AB (SMC) package is a standard surface-mount footprint for this power class, and the tape-and-reel delivery suits automated assembly lines. ## Clamping voltage and breakdown margin Minimum breakdown voltage is 20V, giving a 2V guard band above the 18V reverse standoff before the diode starts conducting significantly. The 29.2V max clamping voltage means the protected circuit must survive that peak during a surge event. Operating temperature spans -65°C to 150°C junction, covering military and industrial thermal profiles without derating concerns at the extremes. Sourced to order against your BOM quantity.","metaTitle":"SMCJ18CAE3/TR13 TVS Diode – 1500W, 18V Standoff, DO-214AB","metaDescription":"SMCJ18CAE3/TR13 bidirectional Zener TVS diode, 1500W peak pulse power, 18V reverse standoff, 29.2V clamping.
