Additional Details

The DMP2130L typically has a drain-source voltage (VDS) rating of -20V and a continuous drain current (ID) rating of around -2.9A. The gate-source voltage (VGS) is typically rated at ±12V. It is available in various surface mount packages such as SOT-23. Key electrical characteristics include its low on-resistance, typically in the range of tens of milliohms, which minimizes conduction losses. It is commonly used with microcontrollers, where a low gate threshold voltage is important for direct drive capability. As an end-of-life product, it may be difficult to source new components, but it may be available from distributors specializing in obsolete or surplus components.
