MCH3322-TL-E is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists onsemi. Its product description is TRANSISTOR. Review the specifications below when checking this part for your BOM.
The MCH3322-TL-E is a single NPN bipolar junction transistor manufactured by onsemi. It utilizes silicon technology and is designed for surface-mount applications in the SOT-23 package. The device supports a maximum continuous collector current of 600 mA and withstands a collector-emitter voltage of 50 V. Key electrical characteristics include a DC current gain (hFE) range of 100 to 300 at IC=100mA, a collector-emitter saturation voltage of 400 mV max at IC=100mA/IB=5mA, and a transition frequency of 250 MHz. It operates within a temperature range of -55°C to +150°C and features a power dissipation rating of 350 mW.
Verify the specific ordering suffix and tape-and-reel quantity against the official datasheet before procurement. Confirm compliance with RoHS and REACH directives as stated in the manufacturer's documentation. Ensure the component status is active and not obsolete. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity.
Select this component for applications requiring moderate current handling and high-speed switching in small form factors. Compare the 50V breakdown voltage and 600mA current limit against circuit requirements. Evaluate the thermal resistance and power dissipation limits relative to the PCB layout. Consider the SOT-23 package constraints for soldering and heat management during design integration.
This component belongs to the MCH series of bipolar transistors from onsemi. It is distinct from other variants such as the MCH6102 or MCH6122, which differ in current ratings and voltage specifications. The MCH3322 is specifically engineered for general-purpose use rather than high-power audio or RF amplification found in other series members.
Consult the official datasheet for direct pin-compatible substitutes. Verify that any alternative NPN transistor matches the 50V VCEO, 600mA IC, and SOT-23 package dimensions. Ensure equivalent hFE and fT characteristics are maintained for circuit compatibility.
