That 600W number is the energy the die can absorb in a single pulse — enough for most industrial surge events on a 48 V or 85 V rail, but not a direct lightning hit. The scorch mark on a dead board tells you whether the TVS held or the downstream IC took the hit. ## Bidirectional — one device for both polarities A single bidirectional channel means the same part clamps positive and negative transients symmetrically. No need to orient the diode on the board — it works either way, which simplifies assembly and reduces polarity errors on the line. ## Breakdown and clamping window Reverse standoff is 85 V — the rail voltage the part sits across without conducting. Breakdown starts at 94.4 V minimum, and clamping maxes out at 151 V at the peak current. That 57 V window between standoff and clamp is the margin your downstream silicon has to survive. If the protected IC's abs-max is below 151 V, this part won't save it. ## Active production — no end-of-life worry Listed as Active by Microchip Technology. No NRND flag, no last-time-buy clock ticking. You can design this in today and expect to buy it next year without a board spin. ## DO-214AA (SMB) — the common footprint Surface-mount in the DO-214AA (SMB) package. Same footprint as the generic SMBJ series — if your BOM already has an SMBJ part, this drops in without a layout change.","metaTitle":"SMBJ85CE3/TR13 TVS Diode – 600W Bidirectional Zener","metaDescription":"SMBJ85CE3/TR13 600W bidirectional Zener TVS, 85V standoff, 94.4V min breakdown, 151V clamping.
