SMBJ5.0CA

SMBJ5.0CA is a bidirectional transient-voltage suppressor diode documented by Shenzhen Ruilon (RUILON) in DO-214AA (SMB), verified against the maker’s own manual row for this code. Verified figures: a 5.0 V reverse standoff, breakdown between 6.40 V and 7.25 V at 10 mA, maximum clamping of 9.2 V at a 65.3 A peak pulse current, and 600 W peak pulse power. Two figures on this row are Ruilon’s own and must not be swapped for another maker’s table: the 7.25 V breakdown ceiling, where several makers print 7.00 V, and the leakage line — the table limit is 800 µA maximum, and the series footnote doubles the limit for bidirectional parts at a standoff of 10 V or below, so the ceiling that applies here is 1600 µA. Selection advice: on a 5 V rail the clamp has to clear the highest normal voltage with margin while still clamping below the downstream absolute maximum; work from this row’s 7.25 V ceiling and 9.2 V clamp, not from a generic SMBJ5.0CA table. Note on attribution: the candidate pool labelled this line R+O (HongJiaCheng); the SMBJ figures in the evidence set are Ruilon’s, so this page is filed under Ruilon pending confirmation of the R+O brand attribution at review. Parameters verified against the RUILON SMBJ series datasheet.
