    I have a Toshiba K20A60U and I can't get the gate to turn on the way I test was diode test mode and (-) to Source and (+) to Gate.

    You could look up the data, like I did.

    The transistor is a high voltage, medium current fet. It has a maximum votage, source to gate, of +/- 30V. Below 30V there will be no current passing in a diode test.

    At some point above 30V, current will pass as you ruin the gate insulation and kill the device.
