2N3904 Description

Short technical summary and product information.

The 2N3904 is an NPN Bipolar Junction Transistor (BJT) registered by Motorola in the mid-1960s, now manufactured by ME. It is designed for general-purpose switching and amplification applications, handling up to 100 mA of current and operating at frequencies up to 100 MHz.

This transistor is characterized by its low-power amplification capabilities and is suitable for low voltage and current applications, not for power amplification. Key electrical specifications include a maximum collector current of 200 mAdc and a maximum base-emitter voltage of 6 Vdc. The DC current gain (hFE) ranges from a minimum of 40 at 0.1 mA to a maximum of 300 at 10 mAdc.

The 2N3904 is commonly available in the TO-92 package, but also in SOT23 and SOT223 surface-mount packages. Its suitability for general-purpose use makes it a versatile component in various electronic designs requiring reliable amplification and switching.
