PNDS / Marking codes / BDE

Identify an unknown SMD part: marking code “BDE”

Packages rarely print the full part number. The marking below is shared by several part numbers — use the package, pin count and the manufacturer family together to narrow it down, then confirm against the datasheet.

How we narrow this down

  1. Package first — SOT-23 vs SOD-123 vs SC-59 eliminates most candidates immediately.
  2. Pin count and body size — a 3-pin SOT-23 LDO cannot be a 6-pin dual transistor.
  3. Marking style — laser-marked parts are usually newer production; ink marking often indicates older or second-source vendors.
  4. Circuits around it — a part sitting on a rail with an inductor is a regulator, not a diode.
  5. Datasheet check — every credible candidate lists its marking scheme in the “marking information” section.

Still not sure what the part is?

Send the code, package and a photo through the BOM hub — our engineers cross-check it against datasheets and sourcing records.

How these mappings are compiled: public SMD marking directories plus our own stock records. Each row keeps its original reference internally, so any mapping can be traced on request. * Manufacturer derived from the part-number family (some directory entries carry no manufacturer) — treat it as a lead, not a datasheet fact. Markings are indicative only — confirm with the physical batch marking and the original datasheet before ordering.
