Overview
The SMDB3 is a trigger Diode made by STMicroelectronics in a SOT-23 package with 3 pins. -40℃~+125℃@(Tj) 1A 28V~36V 2us 32V 50uA SOT-23 Trigger Diodes ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:SMDB3, from EasyEDA) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C114036).
