DY294_V3.pdf6. Testing methods for other components: a. The testing method for operating voltage drop of controlled silicon is the same as that for saturation voltage drop of common transistor in Vce (sat) step. The transistor with low voltage drop has low internal impedance and high output power. The testing method for operating current of controlled silicon is the same as that for transistor hFE step. The level of trigger current should be noted when testing controlled silicon. Insert A pole into C jack, G pole into B jack and K pole into E jack. b. Identify the output power level of transistor , controlled silicon and field effect transistor.Use Vce (sat) steps to test the transistor of the same model. The low saturation voltage drop indicates low internal impedance and high output power. c.To identify unidirectional controlled silicon and bidirectional controlled silicon, first use Vce (sat) or hEF steps of tester NPN to test. d.Identify damp of transistor. The V ( br ) step of the tester can
