【 Weak current College 】 Schottky Diode test 】

2-terminal type Schottky Diode can use multimeter measuring R× 1 stall. Normally, the positive resistance value (black table amount received positive) 2.5 ~ 3.5 Ω, into the resistance value is infinite. If there are positive and negative resistance value is infinity or are close to 0, the diode breakdown is open or damaged.

Three-side-Schottky Diode should detect the public side, identify common on tube, or a total of Yang on the tube, then measure two diodes, reactive resistance values.
