MQ3743 PNP Transistor

The MQ3743 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the MQ3743 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The MQ3743 transistor symbol shows an arrow from the emitter into the base. This means that the current flows from emitter to collector terminal.

Circuit diagram symbol of the MQ3743 transistor as follows.
