When the surge hits, the diode clamps at 32.4V maximum while shunting 15.4A of peak pulse current in the standard 10/1000 µs waveform. The 500W peak pulse power rating is the energy-handling ceiling — stay under it and the part survives repeated events. ## Package and temperature range — what the DO-214AC means for your board The DO-214AC (SMA) package is a common surface-mount footprint with a 0.050-inch (1.27 mm) lead pitch.","metaTitle":"SMAJ20AE3/TR13 TVS Diode – 20V Standoff, 500W, DO-214AC","metaDescription":"SMAJ20AE3/TR13 Zener TVS, 20V reverse standoff, 32.4V clamp at 15.4A, 500W peak pulse.
