SMBT Description

Short technical summary and product information.

The Infineon SMBT3904E6433 is a single NPN bipolar junction transistor (BJT) designed for switching applications. It features a maximum collector-emitter voltage (VCEO) of 40V and a maximum continuous collector current (Ic) of 0.2A. The transistor has a typical collector-emitter saturation voltage (Vce(sat)) of 0.3V and a minimum gain bandwidth product (fT) of 300 MHz.

This component is housed in a compact SOT-23-3 surface-mount package, making it suitable for space-constrained designs. It operates within a temperature range of -65°C to +150°C. The SMBT3904E6433 is manufactured by Infineon Technologies and is part of the SMBT3904 series.

Key electrical characteristics include a collector-base voltage (VCBO) of 60V and an emitter-base voltage (VEBO) of 6V. The power dissipation (Pd) is rated at 330mW. This transistor is ideal for general-purpose switching and amplification circuits where a small, reliable NPN transistor is required.
