PEAK REVERSE VOLTAGE
It is the maximum reverse voltage (cathode positive w.r.t anode) that can be applied to an SCR without conducting in the reverse direction.
Peak reverse voltage(PRV) is an important consideration while connecting an SCR in an a.c circuit. During the negative half of a.c supply, reverse voltage is applied across SCR. If PRV is exceeded, there may be avalanche breakdown and the SCR will be damaged if the external circuit does not limit the current.
