Breakdown occurs at a minimum of 56.7V, clamping at 91.1V max at the peak pulse current of 6.6A. That 91.1V clamp is the voltage the downstream circuitry must survive during a surge event. ## DO-214AA footprint and temp range ## Single-channel unidirectional protection A single unidirectional channel — suitable for DC rail protection where polarity is fixed. No power line protection feature (internal crowbar or foldback), so it relies on the Zener avalanche effect alone.","metaTitle":"SMBJ51E3/TR13 Zener TVS Diode – 600W, 51V, DO-214AA","metaDescription":"SMBJ51E3/TR13 Zener TVS diode, 600W peak pulse, 51V standoff, DO-214AA.
