Its 22.2V minimum breakdown voltage and 35.8V maximum clamping voltage define the protection window: the rail sees no more than 35.8V during a surge event. The 600W peak pulse power rating at 10/1000µs waveform tells you how much surge energy it can absorb — enough for typical industrial or automotive transient protection on a 20V bus. ## Peak pulse current and temperature range Rated for 16.7A peak pulse current under the 10/1000µs waveform, the diode can handle brief high-current spikes without failing. ## Active production in DO-214AA package","metaTitle":"SMBJ20E3/TR13 Zener TVS Diode – 20V, 600W, DO-214AA","metaDescription":"SMBJ20E3/TR13 Zener TVS diode, 20V reverse standoff, 600W peak pulse, DO-214AA SMB package.
