Hey guys,
I have a PBSS4140T transistor in a circuit to control a oven heater.
Only with the same programming as with my previous BC337 transistors, the transistor is not opening.
Here is my schematic:

Do you see something i do not see.
The system is connected to the analog pins of an arduino GIGA R1
