RUILON

RUILON is the catalog short name for Shenzhen Ruilon Electronics, a maker of transient-voltage suppression devices whose SMBJ and SMAJ manuals document the industry-standard TVS designations under its own electrical tables. The profiles here cover four bidirectional codes: the SMBJ5.0CA, SMBJ6.5CA and SMBJ15CA in the DO-214AA (SMB) case, and the SMAJ5.0CA in the smaller DO-214AC (SMA) case. Two reading habits matter with these tables. The breakdown ceilings are Ruilon’s own — the SMBJ5.0CA row closes higher than several other makers print for the same designation, and the SMBJ15CA window is wider again — so qualify a protection design against the table of the maker actually supplied. And the series footnote doubles the leakage limit for bidirectional parts at low standoff voltages; the part pages present both the table figure and the doubled ceiling, so the power budget is not read wrong.

Sourcing notes for RUILON parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
