Single Bipolar Transistors Procurement Notes

Verify the specific suffix E6327 against official Infineon documentation to confirm packaging and tape-and-reel specifications. Confirm component availability status as some BC817 variants are marked obsolete. Ensure RoHS compliance details match current regulatory requirements for your region before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring an NPN transistor with 45V breakdown and 500mA continuous current in a surface-mount package. Consider the complementary BC807 series for PNP requirements. Evaluate thermal management needs given the 500mW power dissipation limit in the SOT-23 form factor.

Single Bipolar Transistors Part Context

This part belongs to the BC817 family of NPN silicon transistors intended for audio frequency use. It is functionally similar to other industry-standard small-signal NPN transistors but offers specific gain and saturation characteristics defined by Infineon. The E6327 suffix typically denotes specific packaging or ordering information rather than a change in electrical function.
