Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm exact electrical characteristics and packaging details. Ensure the component meets automotive quality standards if required for the target application. Cross-reference datasheet parameters with design specifications before finalizing procurement orders.

Selection Notes

Select this component for designs requiring a compact NPN transistor with moderate current handling. The SOT-23 package suits space-constrained PCB layouts. Consider the available current gain bins to match circuit sensitivity requirements. Verify thermal management needs relative to the 250 mW power dissipation limit.

Part Context

This part belongs to the BC817 series of NPN general-purpose transistors from Nexperia. The series includes variants with different voltage ratings and current gains, all sharing the same small outline plastic package. These devices are widely used in consumer and industrial electronics for signal processing and power control tasks.

Replacement Considerations

Compatible substitutes include the BC817-40-QVL and BC817-16-QVL within the same product family. Ensure pinout compatibility and verify that alternative suffixes meet the specific voltage and current gain requirements of the original design.
