TN5D01A no. a1446-9/11 example of over-voltage protection circuit. generally, in constant-voltage power supply circuit, output voltage will become higher than the speci ed value (over-voltage state) in case of any failures or pc board solderability defects. to minimize the damage caused by this over-voltage, we recommend setting an over-voltage protection circuit. in designing, the following con rmations are necessary in actual circuit. 1) how the over-voltage protection circuit operates and its effects. 2) is there any malfunction due to ambient temperature change of each device or exogenous noises? over-voltage protection circuit example example of over-voltage protection circuit. the thyristor will operate when it accept an over-voltage (v out ) signal, then the fuse is melted and the input power is cut off, then the operation of ic1 is stopped. continued on next page. v in gnd gnd v out fuse f1 constant-voltage power supply c zd r thyristor + + v in gnd gnd v out 1 thyristor fuse f1 ic1 5 234 c zd r
