MMBT3904 Description

Short technical summary and product information.

The MMBT3904 is an NPN bipolar junction transistor (BJT) designed for medium-power amplification and switching applications. It comes in a compact SOT-23 surface-mount package, making it suitable for space-constrained designs.

 

Key electrical characteristics include a maximum collector-emitter voltage of 40V and a maximum collector current of 200mA. The transistor exhibits a DC current gain (hFE) of at least 100 at 10mA and 1V, and a Vce saturation of 300mV maximum at 5mA/50mA. Its frequency response extends to 300MHz.

 

This device operates within a temperature range of -55°C to 150°C. It is packaged in a molded plastic "Green" compound with matte tin-plated leads, solderable per MIL-STD-202, Method 208. The MMBT3904 is noted as being totally lead-free and fully RoHS compliant, as well as halogen and antimony-free.

 

Its complementary PNP type is the MMBT3906. An automotive-compliant version is available under a separate datasheet.
