Procurement Notes

Verify the specific suffix '16' against official Infineon documentation to confirm the exact hFE binning requirements, as suffixes often denote specific gain ranges or packaging variations. Confirm RoHS compliance status through the manufacturer's environmental declaration. Ensure the PG-SOT323 footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN transistor with moderate current capacity is required for space-constrained designs. The PG-SOT323 package offers a small form factor suitable for high-density mounting. Consider the 100 MHz transition frequency for applications requiring moderate speed, while ensuring the thermal management strategy accommodates the 310 mW power dissipation limit in the chosen enclosure.

Part Context

This part belongs to the BC817 series of NPN transistors produced by Infineon Technologies. The series is widely recognized for its reliability in consumer electronics and industrial control systems. The specific model integrates standard electrical characteristics optimized for cost-effective mass production while maintaining strict quality standards defined by automotive and industrial certifications.

Replacement Considerations

Consult official cross-reference lists for verified substitutes such as BC817-16 variants from other manufacturers. Ensure replacement parts match the PG-SOT323 package dimensions and pinout configuration. Verify that alternative components meet or exceed the 45 V VCEO and 500 mA Ic specifications to maintain circuit integrity.
