I am driving columns of eight PIN diodes, each in an array for a project. All of the columns are tied to a common ground. I expect the current of the parallel diodes to be approximately 90 mA (11 mA per diode x 8). See schematic below. I am using the Arduino Uno R3 as my digital controller. To my un…

How to drive eight PIN diodes in parallel with 90 mA current using Arduino Uno R3

Are ALL the PIN diodes from the same wafer? How do insure they will all conduct identical currents and at the SAME time?
