Pin	Signal	Direction	Function
1	G Input	Input	Gate. Drive with the rated voltage relative to its own source.
2	S Current terminal	Current terminal	Source. It sets the gate-voltage reference and is the intrinsic diode anode.
3	D Current terminal	Current terminal	Drain. It connects to the switched load and is the intrinsic diode cathode.

With the source on the return and the drain on the load, a positive gate-to-source voltage turns on the channel.

Parameter	Limit	Conditions and source
Drain-to-source voltage20 V	20 V	Absolute maximum with the gate off. Allow margin for supply and switching transients. Infineon IRLML2502PbF, Absolute Maximum Ratings
Gate-to-source voltage±12 V	±12 V	Absolute maximum. Gate drive in this example is 5 V. Infineon IRLML2502PbF, Absolute Maximum Ratings
Maximum on-resistance45 mΩ	45 mΩ	At VGS = 4.5 V and TJ = 25 °C. The manufacturer separately specifies on-resistance at 2.5 V. Infineon IRLML2502PbF, Electrical Characteristics

Three-terminal Micro3. Drain is the single lead opposite the gate and source.
