What is the component in SOT23-3 with marking F1 and lying 8 or infinity mark, please?

This is a part of Semikron inverter board. Pictures:

Looks like it is a SOT23.

The point mark under the "1F" and the one digit orthogonal lot code is typical from ONSEMI. So it might be BC847BLT1G / BC847BLT3G.



It is probably a BC847B NPN, 45 V, 100 mA NPN general-purpose transistor.

Made by various manufacturers including NXP, most using a 1F main marking, with various lot codes (the 8).
