Description: BS170 N-Channel Switching FET Transistor

BS170 BS-170 BS 170 60V 0.5A N-Channel Enhancement Mode Field Effect Transistor TO-92 Package Switching FET Triode Transistor

BS170 is a well-known N channel MOSFET manufactured in TO-92 package. It can be used for both switching and amplification purposes. When used as switch it can drive load of 500mA. It is able to perform fast switching and capable to switch load in around 7 nanoseconds due to which it can be used in high speed circuits. It can also perform well on low voltage due to which it is an ideal MOSFET to use in portable and battery operated applications.

Other than that it can also be used as an amplifier and you can use it in your audio amplifier circuits and also for any general purpose signal amplification requirements.

These N-Channel enhancement mode field effect transistors are produced using high cell density, DMOS technology. These products have been designed to minimize on-state resistance while provide rugged, reliable, and fast switching performance.
They can be used in most applications requiring up to 500mA DC. These products are particularly suited for low voltage, low current applications such as small servo motor control, power MOSFET gate drivers, and other switching applications.

Where We Can Use it & How to Use:

BS170 can be used for any general purpose switching and amplification purposes, it can be used as a switch to drive loads under 500mA which is enough drain current to drive most of the relays, lamps, LEDs etc. Additionally it can also be used at the output of microcontrollers and platforms like arduino and raspberry pi to drive loads.

On the other hand it can also be used as an audio amplifier, in audio amplifier stages, low level signal amplification etc. Wiring the MOSFETs are almost same as we wire BJT transistors. In MOSFETs the Gate is used to control the transistor where as in BJT it is Base, but the BJTs are current control devices and MOSFETs are voltage control devices. And the gate in MOSFETs requires small amount of voltage to control current through its Drain to Source.

Applications:

• Fast Switching
• Switching or driving loads under 500mA
• Audio Amplification & Pre Amplification
• Output of Microcontrollers
• Output of ICs
• Various type of signal amplification

How to Safely Long Run in a Circuit:

To get long term and stable performance from BS170 MOSFET in your circuits do not drive load of more than 60V and 500mA. The Gate to Source voltage should be under ±20V and do not operate and store the transistor in temperature below -55 Celsius and above +155 Celsius.
