MMBT2222A Description

Short technical summary and product information.

The MMBT2222A is an NPN switching transistor designed for applications requiring both switching and linear amplification. It is packaged in a compact SOT23 plastic surface-mount package, making it suitable for space-constrained designs.

 

This transistor features a high collector current capability of up to 600 mA and a maximum collector-emitter voltage of 40 V. Key electrical characteristics include a DC current gain (hFE) ranging from 35 to over 300 depending on the operating conditions. Its switching performance is defined by parameters such as turn-on time (35 ns max), turn-off time (250 ns max), rise time (20 ns max), and fall time (60 ns max).

 

The MMBT2222A operates within a wide ambient temperature range of -65 °C to +150 °C and has a junction temperature limit of 150 °C. The thermal resistance from junction to ambient is 500 K/W when mounted on an FR4 printed-circuit board.

 

Its PNP complement is the PMBT2907A. The SOT23 package is ideal for surface mounting, facilitating automated assembly processes.
