This series features DB3 trigger diodes, available in DO‑35 axial through‑hole and SOT‑23 SMD packages. It delivers stable bidirectional triggering performance with consistent break‑over voltage, low break‑over current and good pulse‑withstand capability, RoHS compliant.
Key Differences Between Models:
DB3 (DO‑35 axial): Through‑hole glass package, for manual & wave soldering, 5000PCS per box
SMDB3 (SOT‑23 SMD): Surface‑mount type for automated SMT assembly, 3000PCS per reel
These diodes feature wide operating temperature and high reliability for long‑term stable operation. They are widely applied in triac trigger circuits, lamp ballasts, light dimmers, motor speed control and other AC phase‑control circuits. Bulk stock available, samples and datasheets can be provided upon request.
