Did you know?
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. Figures 6 to 14 show a selection of alarm circuits of this type. All of these are designed around the inexpensive type C106 SCR ... Webholding current varies inversely with the temperature. Thus, as the temperature decreases, the holding current increases and the phenomenon described in example 2 occurs. Again, …
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 ...

The device performs in much the same manner as a p–n …
WebA silicon-controlled switch (SCS) behaves nearly the same way as an SCR; but there are a few differences: Unlike an SCR, an SCS switches off when a positive voltage/input current is applied to another anode gate lead. …
WebNov 19, 2024 · Holding current in thyristor or SCR can be defined as, the smallest amount of current under which anode current has to drop to enter OFF status. This means, if the holding current value is 5 mA, subsequently thyristor’s anodes current have to turn into less than 5 mA to discontinue performing.
