« Last post by loop123 on Today at 06:49:38 am »here is my initial guess of the effects when the resistors will be removed (see previous sketch).
For normal use where the input voltage would be less than the forward bias voltage of the diodes (less than 0.7 Volts). There would be no harmful effects even if the diodes remain in place and the 2 resistors removed. Right?
But for surges or ESD events where the diodes conduct producing voltage potential of 8V (source is Ni-MH rechargeable batteries)-0.7 (diode) = 7.3 volts. The higher input surge voltage of say 50V can charge the power source or rechargeable batteries. Can momentary charging by the surges/ESD cause the batteries to explode?
What ESD protection devices do you know that don't use any resistor in series to the source? I have to avoid any resistors to eliminate any noises since I need ultra low noise sensor.
