MMBT3904-7-F Description

Short technical summary and product information.

The MMBT3904-7-F from Diodes Incorporated is an NPN bipolar junction transistor (BJT) suitable for medium power amplification and switching applications. This device operates with a maximum collector-emitter voltage of 40V and can handle a continuous collector current of up to 200mA.

 

It is housed in a compact SOT-23-3 surface mount package, making it ideal for space-constrained designs. The transistor offers a DC current gain (hFE) of at least 100 at 10mA and 1V, with a Vce saturation of 300mV maximum at 5mA and 50mA. Its operating frequency reaches up to 300MHz.

 

The MMBT3904-7-F is designed for surface mounting and features matte tin plated leads, solderable per MIL-STD-202, Method 208. It operates within a wide temperature range of -55°C to +150°C. The device is also noted for its environmental compliance, being Totally Lead-Free & Fully RoHS Compliant and Halogen and Antimony Free.

 

This transistor is a complementary PNP type available as the MMBT3906. An automotive-compliant version is also available under a separate datasheet.
