Darlington NPN 100V 5A 3-Pin (3+Tab) TO-220AB transistor in TO-220 package.
To see if your transistor is bad, use a digital multimeter set to the diode check mode.
(-) = negative/black test lead
(+) = positive/red test lead.
Pin 1 = the pin with a dot above it.
For TIP122s, these are typical voltage drop values when measured with a typical multimeter in diode test mode.
When replacing TIP122 transistors, verify that the diode on the coil in question is not shorted, or the replacement will fail.FromToValue1 (-)2 (+)open1 (-)3 (+)1.84Pin 2 (-)Pin 3 (+)0.55 VPin 1 (+)Pin 2 (-)0.63 VPin 1 (+)Pin 3 (-)0.75VPin 2 (+)Pin 1 (-)openPin 2 (+)Pin 3 (-)open
