Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm the package type. The provided datasheet indicates that the 'S1' suffix corresponds to the SOT-23 package configuration. Ensure the selected variant matches the required pinout and thermal specifications for the target design.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring small form factor NPN transistors with moderate current handling capabilities. Consider the complementary 2SA733 PNP transistor for push-pull or differential amplifier configurations. Evaluate thermal management requirements based on the 200 mW power dissipation limit in the SOT-23 package.
