News:

May 23 2016: the iOS application is being updated and will be available mid June 2016. The current version (0.0.1) available in the AppStore supports the B35T but not the B35T+.

July 13 2016: OWON Engineers are still working on integrating the old version of B35T with the new version in a single iOS app. In the meantime, you can download it from: https://www.pgyer.com/iosMultimeterOffline with password 123456. You will need to give permission to execute in your iOS device by going to the settings menu.

The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of transistor used for amplifying or switching electronic signals.

The MOSFET is by far the most common transistor in both digital and analog circuits, though the bipolar junction transistor was at one time much more common.

The main advantage of a MOSFET over a regular transistor is that it requires very little current to turn on (less than 1mA), while delivering a much higher current to a load (10 to 50 times or more).

PACKAGE:
TO-220

A microcontroller (i.e. Arduino) pin can source or sink only 20mA to 40mA (1 or 2 LEDs). The IRF520 can be used to drive motors and other high current devices.
