At 274.8 A through the clamp, the diode absorbs the surge energy and dissipates it as heat across the Zener junction — the 150 °C maximum junction temperature is the ceiling the design must stay below during the surge event. The -55 °C cold-end rating means the TVS conducts properly at cold start without thermal runaway on initial turn-on. ## Telecom bus protection — why 11V standoff The 11 V standoff rating places this part on the standard telecom dc power bus protection rail — 12 V nominal lines feeding base-station rectifiers, fiber-optic shelf power, and dc distribution panels use exactly this standoff window. The 5.0SMDJ series spans multiple standoff voltages across the family, so the 11V variant is the correct fit for 12V telecom supply rails without overshooting the working voltage. ## DO-214AB SMC package for automated placement Surface-mount DO-214AB (SMC) package is the industry-standard form factor for 5 kW TVS diodes — the wide body gives the junction enough die area to handle the peak pulse energy, and the gull-wing leads take IR reflow profiles without cracking. Order in Tape & Reel for high-volume SMT line placement or Cut Tape for prototype and short-run board assembly.","metaTitle":"Bourns 5.0SMDJ11A TVS Diode, 5kW, 11V Standoff, SMC","metaDescription":"Bourns 5.0SMDJ11A unidirectional TVS Zener, 5kW peak pulse, 11V standoff, 18.2V clamping, -55°C to 150°C, DO-214AB.
