Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'A1G' against official Taiwan Semiconductor documentation to confirm the manufacturing code and packing configuration. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity and adherence to the specified RoHS and lead-free terminal requirements.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with a 45V collector-emitter voltage and 800mA current capacity is required. The '40' designation indicates a specific DC current gain grouping; verify that this gain range aligns with the circuit design requirements compared to other groups such as -16 or -25 available in the same series.

Single Bipolar Transistors Part Context

This part belongs to the BC337/BC338 family of NPN transistors manufactured by Taiwan Semiconductor. The series is subdivided into three distinct current gain groups (-16, -25, and -40) to accommodate varying performance needs. The BC338 variant specifically offers higher current handling capabilities compared to the BC337 counterpart while sharing similar voltage ratings and package styles.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include the BC338-16 and BC338-25 variants from the same manufacturer, provided their respective current gain specifications meet the application requirements.
