MMBT2222AW_R1_00001

Single Bipolar Transistors Overview

The MMBT2222AW_R1_00001 is an NPN general-purpose switching transistor manufactured by Panjit International Inc. It utilizes an epitaxial silicon planar design housed in a SOT-323 plastic case. Key electrical ratings include a collector-emitter voltage (VCEO) of 40 V, a collector-base voltage (VCBO) of 75 V, and a continuous collector current (IC) of 600 mA. The device supports a maximum power dissipation of 150 mW with a thermal resistance from junction to ambient of 830 °C/W. DC current gain (hFE) ranges from 35 to 300 depending on the operating current conditions.

Single Bipolar Transistors Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific ordering suffix matches the required packaging format, such as tape and reel quantities. Ensure compliance with environmental directives like RoHS and halogen-free requirements during procurement. Request lot numbers for traceability purposes when placing orders.

Single Bipolar Transistors Selection Notes

Select this component for low-voltage switching tasks requiring compact surface-mount integration. Evaluate the 150 mW power dissipation limit against thermal constraints in the target application. Consider the hFE range variations across different collector currents when designing bias networks. Verify that the SOT-323 package dimensions fit the available PCB space.

Single Bipolar Transistors Part Context

This part belongs to the MMBT2222 series of NPN transistors produced by Panjit. It serves as a compact alternative to larger packages while maintaining similar electrical characteristics for general-purpose use. The SOT-323 form factor allows for high-density mounting on printed circuit boards compared to traditional through-hole options.

Single Bipolar Transistors Replacement Considerations

Cross-reference with other manufacturers offering NPN transistors in the SOT-323 package with comparable VCEO and IC ratings. Verify pinout compatibility and thermal resistance values before substitution.
