                            the diode stops conduction. 
                         
                    
                    
                                                                                
                    
                    
                                                                                
                            
                                
                            
                            
                                
                            
                            
                                
                            
                            the diode conducts heavily in the forward direction. 
                         
                    
                    
                                                                                
                    
                    
                                                         
                    
                            
                    ব্যাখ্যা: ব্যাখ্যাঃ It is the peak inverse voltage rating (PIV) of a diode. When the voltage applied to a doide is more than PIV, it is likely to result in breakdown at the junction and the diodes gets destroyed.
