MMBT3904T-7-F Description

Short technical summary and product information.

The MMBT3904T-7-F from Diodes Incorporated is an NPN bipolar junction transistor designed for small signal applications. It features a collector-emitter voltage (VCEO) rating of 40V and can handle a continuous collector current (IC) of up to 200mA.

 

This transistor is constructed using epitaxial planar die technology and comes in an ultra-small SOT-523 surface mount package. Its electrical characteristics include a DC current gain (hFE) of 100 at 10mA and 1V, and a saturation voltage (Vce Sat) of 300mV maximum at 5mA and 50mA. The device operates at frequencies up to 300MHz.

 

Designed for high reliability, the MMBT3904T-7-F is qualified to AEC-Q101 standards. It is also noted as being totally lead-free, fully RoHS compliant, and halogen and antimony free, making it a 'Green' device. The operating temperature range is -55°C to +150°C.

 

The SOT-523 package is suitable for surface mounting, and the terminals are finished with matte tin plating, ensuring solderability per MIL-STD-202, Method 208. The weight of the component is approximately 0.002 grams.
