Zeus MOSFET Matching


Mosfets mounted on an aluminium plate.


L200 current source mosfet matching circuit.

  • Use 12 volts for IC1 (STMicroelectronics L200) Vsupply.

  • Digital voltmeter to three decimal places at 2 to 6 volts recommended.

  • Current set to 500mA (higher current cause device heating).

  • Mount DUTs on common heatsink as per picture.

  • Allow reading to stabilize (about 10 seconds) before noting value.

  • Once close matches have been ascertained retest those matches to get best fits.
