Product Description

The modules use the D4184 N-channel MOSFET which has a typical low Rds (on) resistance of 8.5mΩ.

These modules support approximately 10A of direct current with a charging voltage of 12V. If driven with PWM, the maximum peak current can be higher up to 20A or more.

The design of these modules includes an optoisolator on the input so that the input is biased from the output load voltage and is independent of the logic levels used for the control signal.

A 3.3 V input will conduct as much current as a 5 V input, for example. Note that the module does not have a fly-back diode on the board.

If you are using the module with inductive loads, an external feedback diode must be used to avoid possible damage.
