Frequently asked questions
What is the price of BSS138 N-Channel MOSFET 50V 220mA SOT-23 SMD in Egypt?
BSS138 N-Channel MOSFET 50V 220mA SOT-23 SMD currently costs 2.5 EGP in Egypt.
Where can I buy BSS138 N-Channel MOSFET 50V 220mA SOT-23 SMD in Egypt?
BSS138 N-Channel MOSFET 50V 220mA SOT-23 SMD is available from Makers Electronics. Compare the offers above to find the best price.
How do I wire it for logic level shifting?
Connect the gate to the low-voltage supply (e.g. 3.3 V), the source to the low-voltage signal line, and the drain to the high-voltage side through a pull-up resistor (e.g. 5 V). The same circuit works in both directions.
Can it drive a relay or motor directly?
Its 220 mA continuous current rating limits it to small loads. For relays, motors or LEDs drawing more current, use a suitable driver transistor or MOSFET.
