In an SCR, the latching current is __________ the holding current

WebThe holding current value IH (refer to AN302 for holding current) is linked to the latching current value IL. For the most TRIACs (rated current lower than 40 A), the IL value is higher than the IH value. The IL /IH ratio is related to the TRIACs current rating, as shown Table 2. Table 2. Approximate ratio between I + +--+-QII QI QIII QIV V T I ... WebThe circuit can be made fully self-latching, if desired, by shunting the load with resistor R3, as shown, so that the SCR anode current does not fall below the SCR's minimum holding value as the load self-interrupts.
