Rated for 600W peak pulse power, this part handles surge events typical of industrial control, telecom, and general-purpose power buses — the 70V standoff suits 48V telecom rails or 60V nominal battery systems where transient spikes can exceed 100V. This is a current-design-in part — no rush to stockpile or find a drop-in replacement. ## Sourcing and fit for your BOM line This is a standard TVS diode — no power-line protection feature (no internal crowbar or SCR structure), so it is strictly a voltage-clamping device for signal or low-power DC rails. The unidirectional channel means it protects one polarity; for AC or bidirectional rails, a different SMBJ variant is needed. No stock-holding claim; sourced through independent distribution per your delivery schedule.","metaTitle":"SMBJ70E3/TR13 TVS Diode – 70V Standoff, 600W, DO-214AA","metaDescription":"SMBJ70E3/TR13 Zener TVS diode: 70V reverse standoff, 77.8V min breakdown, 125V clamping, 4.8A peak pulse.
