Clamping starts at 47.8V breakdown minimum and holds the surge to 69.4V max at the 8.6A peak pulse current. The 600W peak pulse rating is for the standard 10/1000µs waveform; for shorter transients the diode absorbs proportionally more energy. ## 600W peak pulse, DO-214AA SMB package The DO-214AA (SMB) package is a surface-mount footprint that fits standard reflow profiles — no through-hole hand-soldering on the line. ## Active production, Tape & Reel delivery","metaTitle":"SMBJ43AE3/TR13 TVS Diode – 43V Standoff, 600W, DO-214AA","metaDescription":"SMBJ43AE3/TR13 Zener TVS, 43V reverse standoff, 69.4V clamping, 600W peak pulse, DO-214AA SMB.
