This 126 V clamping ceiling is the design limit — the downstream IC sees that voltage, not the full surge amplitude, so the protected rail must tolerate 126 V briefly during an event. ## Package and reel sourcing Supplied on Tape & Reel in the standard SMC footprint — the DO-214AB land pattern is consistent across most TVS families in this case size, but any footprint substitution should verify the clamping voltage and peak current match the Bourns spec, not just the package.","metaTitle":"5.0SMDJ78CA-QH TVS Diode, 78V Standoff, 5kW Peak","metaDescription":"Bourns 5.0SMDJ78CA-QH unidirectional Zener TVS, AEC-Q101, 78V standoff, 126V clamping, 5kW peak pulse, DO-214AB SMC.
