Where to Use BS170 MOSFET?

Manufactured through DMOS technology, best suited for low voltage, low current applications like servo motor control, power MOSFET gate drivers and other switching application. BS170 used in most application which requires up to 500mA DC current. Also, used in High-speed circuits.

 

How to Use BS170 MOSFET?

In this circuit, we are just turning ON/OFF an LED using BS170 n-channel MOSFET. Here, the Gate and Drain terminal are connected through a 5v DC source and LED is connected to the Source. As the gate pulse applied by turning ON the switch, MOSFET conduct current through Drain to Source and LED start glowing. LED remain ON until the gate pulse applied. As the gate pulse removed LED turns OFF.
