SAV-581+

Mini-Circuits · Low Noise Amplifiers (LNA) - RF · SOT-343

SAV-581+ from Mini-Circuits, in a SOT-343. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	DRAIN	passive	Drain terminal used for the RF output; datasheet maximum drain-source voltage is 5 V and maximum drain current is 100 mA.
2	SOURCE	passive	Source terminal, normally connected to ground; datasheet maximum gate-source voltage range is -5 to 0.7 V.
3	GATE	input	Gate terminal used for the RF input; datasheet maximum gate current is 2 mA and maximum gate-drain voltage range is -5 to 0.7 V.
4	SOURCE	passive	Second source terminal, normally connected to ground, internally common with pin 2 per the datasheet pin description.
