Identify SMD (SMT) electronic components by their marking codes. Our database currently has 3343 SMD marking codes of bipolar transistors (BJT), field effect transistors (FET, MOSFET, JFET), diodes, Zener diodes, Schottky diodes, varicap diodes, voltage supervisors (reset circuits), temperature sensors, current sensors, transient voltage suppressors (TVS) and others.
Fill in the marking code found on the top surface of the SMD component, then fill in the human verification number, which ensures only real people use the data and click the "Search" button. Searching is case-sensitive. If any Partnames are found, you could further search these on the manufacturer's website. Our database contains marking codes of some popular SMD electronic components in very small packages that typically can not carry the full name of the component. These include bipolar junction transistors (BJTs), field effect transistors (FETs, MOSFETs), junction gate FETs (JFETs), diodes, Schottky diodes, Zener diodes, varicap (variable capacitance, or varactor) diodes, voltage supervisors (reset circuits for microcontrollers), transient voltage suppressors (TVSs), ESD protection diodes and other components.
