Frequently asked questions
What is the price of 3DD127D NPN Power Transistor 400V 2.5A 50W TO-126F in Egypt?
3DD127D NPN Power Transistor 400V 2.5A 50W TO-126F currently costs 20 EGP in Egypt.
Where can I buy 3DD127D NPN Power Transistor 400V 2.5A 50W TO-126F in Egypt?
3DD127D NPN Power Transistor 400V 2.5A 50W TO-126F is available from Makers Electronics. Compare the offers above to find the best price.
How do I identify the pins on TO-126F?
The pin order (Emitter-Base-Collector or Base-Collector-Emitter) depends on the manufacturer. Check the datasheet, and if it is unclear, use a multimeter in diode mode to identify the base and junctions before powering the circuit.
Can I use it to switch a motor or a high-power LED?
It can switch loads within its ratings, but a 5V microcontroller pin usually cannot supply enough base current. Use a driver stage, and check the gain and saturation values in the datasheet.
