Product Details

Maxim Ideal Diode

The Maxim SOT23-5 single channel 5-pin ultra-tiny micropower ideal diode has a supply voltage rating of 5.5V and a continuous current rating of 1A. It has a quiescent current rating of 18μA. The voltage drop is 43mV at 500mA, with the voltage drop increasing linearly at higher currents. MAX40200 thermally protects itself and any downstream circuitry from over-temperature conditions. When disabled (EN = low) the MAX40200 blocks voltages up to 6V.
