About this product
BF469 is an NPN high-voltage transistor, historically used in the video output stages of CRT televisions and monitors. It is suited to high-voltage switching and amplifier circuits where the collector must withstand large voltages. Verify the package and voltage rating in the datasheet before designing it into a circuit.

Frequently asked questions
Can BF469 be used in a low-voltage project like an Arduino circuit?
It works, but it is designed for high voltage rather than general switching, so a common low-power NPN such as BC547 or BC549 is usually a simpler choice for low-voltage logic-level projects.
How do I confirm the pinout before wiring it?
Check the package drawing and pin assignment in the manufacturer datasheet, because the listing package may differ from the datasheet package. Do not rely on the physical shape alone when wiring the emitter, base, and collector.
