SMMBT3904LT1G Description

Short technical summary and product information.

The SMMBT3904LT1G from ON Semiconductor is a general-purpose NPN silicon transistor. It is designed to handle a maximum collector-emitter voltage of 40V and a continuous collector current of 200mA. The device features a DC current gain (hFE) of 100 minimum at 10mA collector current and 1V VCE. Its saturation voltage (VCE(sat)) is a maximum of 300mV at 5mA base current and 50mA collector current.

 

This transistor operates within a junction and storage temperature range of -55°C to 150°C. It is housed in a compact SOT-23-3 (TO-236) surface-mount package, making it suitable for space-constrained applications. The device is also noted for being Pb-Free, Halogen Free/BFR Free, and RoHS Compliant.

 

Key electrical characteristics include a breakdown voltage of 40V (VCEO), 60V (VCBO), and 6.0V (VEBO). The transistor has a transition frequency (fT) of 300MHz. Thermal considerations include a total device dissipation of 300mW on an alumina substrate or 225mW on an FR-5 board at 25°C ambient temperature.
