1.Widely used. 2.High performance-price ratio. 3.The operation is simple and easy to understand. 4.Several types are available to meet different customer needs. 5.Small appearance. It only needs to be connected in series to the positive pole of the circuit, and does not need to be connected to the negative pole. There is no input voltage limit. ( that the reverse voltage is lower than 40V) 300A high current MOS tube, one tube can pass 40A current, two tubes can pass 60A current 1.1 milliohm on-resistance, low loss, low heat generation 2US quickly responds to reverse polarity conditions, input and output are equivalent to diodes. Detect that the output voltage is the input and immediately turn off the output, the detection value is in the millivolt level, and the corresponding speed is very fast -40-125 degrees working environment temperature Circuit board size: 50x34mm Copper foil thickness: 1.5oz Use:Replace ordinary high-current diodes, batteries, solar panels, anti-reflow and anti-reflow. Connecting in series at the input end of the power supply is an Perfect choice for anti-reverse connection. Style: D (Double core with terminal) size:50x34mm Material:PCB colour: Package Contents: 1 * diode module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
