Single Bipolar Transistors Procurement Notes

Verify the specific RoHS compliance status and lead-free certification details directly with the manufacturer or authorized distributors, as documentation indicates potential variations in regulatory compliance records. Confirm the exact package marking and datasheet revision to ensure compatibility with design requirements before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring low-noise NPN amplification within a TO-92 form factor. Ensure the operating collector current remains within the 50mA limit and that the 18V breakdown voltage accommodates the circuit's peak voltages. Consider the thermal constraints imposed by the 625mW power dissipation rating during continuous operation.

Single Bipolar Transistors Part Context

This part belongs to the PN513x series of small signal transistors from Central Semiconductor. It serves as an NPN counterpart to other variants in the family, offering distinct voltage and current characteristics tailored for low-power analog and digital switching tasks in consumer and industrial electronics.

Single Bipolar Transistors Replacement Considerations

Cross-reference with generic NPN small-signal transistors such as the 2N3904 or BC547 if pinout and electrical parameters align. Verify that substitute components meet the specific low-noise requirements and hFE gain ranges defined in the original specifications.
