![]() ![]() The LED will remain on until the gate pulse is activated. When the gate pulse is given by turning on the switch, current flows from Drain to Source, and the LED begins to glow. The Gate and Drain terminals are connected with a 5v DC supply, and the LED is connected to the Source. In this setup, we're merely using a BS170 N-channel MOSFET to turn on and off an LED. This MOSFET has a 3V threshold voltage and is housed in a small TO-92 package, so if you're looking for a small MOSFET to switch a load, this IC might be ideal for you. The 2N7000 MOSFET can switch loads with a voltage drop of fewer than 60 volts (VDS) and a current draw of less than 200 milliamperes (ID). MOSFETs, which are comparable to transistors, are high-current, high-voltage power electronic switches. The 2N7000 is a small-signal N-channel MOSFET. The BS170 is used in most applications that require up to 500mA DC current. Low power Analog converters or inverters BS170 vs 2N7000 Where to use?ĭMOS technology is used in low-voltage, low-current applications such as servo motor control, power MOSFET gate drivers, and other switching applications.Commonly used for small signal switching.Direct Logic-Level Interface: TTL /CMOS.Drivers: Relays, Solenoids, Lamps, Hammers, Displays, Memories, Transistors, etc. ![]() The gate-source voltage (VGS) is around 20 volts.The VGS-th (gate threshold voltage) is 3V.It's ideal for low-voltage, low-current applications.Small signal switch with voltage control.Low ON-state resistance RDS thanks to a high-density cell design (ON).It can deliver up to 2A of pulsed current and is suitable for most applications requiring up to 400mA DC. This high-density approach was designed to reduce on-state resistance while delivering reliable, fast switching performance. The 2N7000 is a high-cell density N-channel enhancement mode Field-Effect Transistor made utilizing Fairchild's DMOS technology. The BS170 is well suited for low voltage and low current applications such as tiny servo motor control, power MOSFET gate drivers, and other switching applications. It can also be used as an amplifier, and it can be used in audio amplifier circuits as well as other signal amplification applications. It can also work at low voltages, making it a good MOSFET for battery-powered applications. It has quick switching capabilities and can switch loads in about 7 nanoseconds, making it suitable for use in high-speed circuits. When used as a switch, it can drive a load of 500mA. It has the ability to switch as well as amplify. This ultra-high-density technology is intended to lower state resistance while providing stable, reliable, and fast switching. This device was made with Fairchild's unique high-density DMOS cell technology. In a TO-92 packaging, the BS170 is a well-known N-channel MOSFET. But what is the difference between the two of them? This article will answer your questions and show you their similarities and differences, as well as their interchangeability. Other variations 2N7002, VQ1000J, and VQ1000P are sometimes listed together on the same datasheet. The 2N7000 and BS170 are two N-channel enhancement-mode MOSFETs with differing lead configurations and current ratings that are utilized for low-power switching applications.
