Additional Details

The I4130 typically features a drain-source voltage (VDS) rating of -30V and a continuous drain current (ID) rating that depends on the package and thermal conditions, but is typically around -5A. The on-resistance (RDS(on)) is very low, generally in the range of 20 mΩ to 50 mΩ at VGS = -10V. The gate threshold voltage (VGS(th)) is typically between -1V and -3V. It's available in surface-mount packages like the TSOP-6 or similar small outlines. This MOSFET is designed to minimize conduction losses and switching losses, making it a suitable choice for high-efficiency power management applications. It also features ESD protection. Because it's avalanche rated, it can withstand certain transient voltage spikes without damage, adding to its robustness. The I4130 is a reliable and efficient P-channel MOSFET well-suited for load switching and power management in portable devices and other power-sensitive applications.
