Scr holding and latching current
Webb15 okt. 2024 · The main difference between latching and holding current of SCR is that latching current is related with turn on process while holding current is related with turn off process of SCR. Latching current of forward biased SCR is the minimum current … Webb9 jan. 2024 · The anode current under this condition is very small (a few mA) and is called holding current. Thus, if an SCR has a holding current of 5mA, it means that if anode …
