International Rectifier IRLB3034PbF, TO-220AB outline and lead assignments

Pin	Signal	Direction	Function
1	G Input	Input	Gate. Drive with the rated voltage relative to its own source.
2	D Current terminal	Current terminal	Drain. It connects to the switched load and is the intrinsic diode cathode.
3	S Current terminal	Current terminal	Source. It sets the gate-voltage reference and is the intrinsic diode anode.
TAB	D Bidirectional	Bidirectional	Metal tab connected to D internally. Include its net when laying out the footprint.

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 voltage40 V	40 V	Absolute maximum with the gate off. Allow margin for supply and switching transients. International Rectifier IRLB3034PbF, Absolute Maximum Ratings
Gate-to-source voltage±20 V	±20 V	Absolute maximum. Gate drive in this example is 5 V. International Rectifier IRLB3034PbF, Absolute Maximum Ratings
Maximum on-resistance2 mΩ	2 mΩ	At VGS = 4.5 V and TJ = 25 °C under the data sheet’s pulsed test. At 10 V gate drive the limit is 1.7 mΩ. International Rectifier IRLB3034PbF, Electrical Characteristics
