HONGJIACHENG

HONGJIACHENG is the catalog short name for Zhuhai HongJiaCheng, the maker whose SMF SERIES manual and discrete datasheets document the protection and rectifier profiles collected here. The hub covers eight codes in the small SOD-123FL and SOD-523 bodies: five SMF transient-voltage suppressors, the DSK24 and DSK34 Schottky rectifiers, and the H3V3LD5B low-capacitance ESD diode for 3.3 V lines. Three cautions run through the line. The SMF leakage figures carry a footnote that doubles the limit for bidirectional parts at low standoff voltages, and the part pages present the doubled ceiling where it applies. The DSK24 voltage row reads 40 V on the maker’s current revision; an earlier misreading of it in our own verification has been corrected. And the candidate pool that surfaced these codes used a brand attribution the manuals only partly support, so each part page here is filed under the maker whose manual its figures were read from.

Sourcing notes for HONGJIACHENG 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.
