First, what is " SCR latch-up? These diodes can act as the gate to the parasitic SCR , and if enough current flows the.
Positive and negative SCR cells are paired to work as active switches. The energy of an ESD discharge is both absorbed and shunted by the SCR to the supply line positive pulse or ground negative pulse.
When the energy is dissipated, the SCR quickly returns to its off state because there is no current to sustain the latched holding condition of the SCR. The SCR cell structures of this. If sufficient clipping current flows the SCR will regenerate and switch into a low voltage on-state condition. As the overvoltage subsides the high holding current of the SCR prevents d.
The device senses the , threshold or trip voltage at which the MC will trigger and supply gate drive to the crowbar SCR , 0 1 , limiting resistor, R g , is given in Figure 9.
Using this value of R g , the SCR , Q1, will receive the , , the power supply, across which the SCR is connected, must be shut down to reset the crowbar.
