- Transition frequency of 300 MHz and hFE up to 300 enable efficient high-gain amplification and fast digital switching
Applications
The PMBT2222A is widely used in switching circuits, low-power amplifiers, and signal conditioning stages in consumer electronics, IoT nodes, and industrial sensors. Its 600 mA / 40 V ratings and SOT-23 footprint make it practical for driving LEDs, relay coils, and logic-level loads in space-constrained PCB designs. The high transition frequency of 300 MHz also suits RF pre-amplifier and oscillator applications in the low-MHz range.

Frequently Asked Questions
What are the maximum collector current and voltage ratings of the PMBT2222A?
The PMBT2222A is rated for a maximum collector current of 600 mA and a collector-emitter voltage (VCEO) of 40 V, making it suitable for switching and amplification tasks in low-power circuits operating up to 40 V supply rails.
How does the SOT-23 package of the PMBT2222A benefit high-density PCB layouts?
The 3-pin SOT-23 package of the PMBT2222A measures approximately 3 mm x 1.4 mm, providing a very small PCB footprint that allows designers to place multiple switching transistors within tight board areas in wearables, IoT modules, and handheld devices.
When would a designer choose PMBT2222A over a through-hole 2N2222A transistor?
A designer selects the PMBT2222A over through-hole 2N2222A when the design requires surface mount assembly, automated pick-and-place production, and reduced PCB size. Both share 600 mA and 40 V ratings with hFE up to 300, but the SOT-23 PMBT2222A integrates into modern SMT workflows with reflow soldering.
