Reverse standoff of 17 V typ sets the normal working rail; the part sits idle below that and activates only when the transient pushes it into breakdown at 18.9 V minimum. ## Telecom fit and SMC package Targeted at telecom line-card protection — the 5-0SMDJ series sits on power rails and data pairs where surge immunity is required. Surface-mount termination accepts reflow profile; the SMC footprint lands on a 3-pin array matching most layouts. Confirm the anode/cathode orientation against the board silkscreen — the unidirectional polarity is not reversible. ## Thermal margin at full surge Junction temperature rated to 150 °C — under a 5000 W pulse the die heats fast, but the 150 °C ceiling is wide enough for the brief thermal spike provided the pulse width stays within the 10/1000 µs window. Repetitive pulses close together narrow the margin; thermal design of the board copper matters for continuous surge exposure.","metaTitle":"Eaton 5-0SMDJ17A Zener TVS, 17V/27.6V clamping","metaDescription":"5-0SMDJ17A unidirectional Zener TVS, 5000W peak pulse, 17V standoff / 27.6V clamping.
