I am using a BCX38C to control the Reed Relay. When the pin on the Picaxe 20m2 is low is there any current draw from the picaxe circuit? I tied a 10k resistor to ground to make sure when the pin goes low the transistor should close all the way. I need all the battery life I can save so I dont want any current draw from the reed relay when the pin is low....Hope this makes sense....I tried to upload a image but it keeps failing to upload for some reason....
No transistor is a perfect switch, but for your application the one you have selected is probably as close as you can get. Worst case, the low Picaxe pin MIGHT leak 100 nanoamp from the transistor base in the transistor off condition. The data sheet is a bit squirrely on this, as are most.
If you really, really, really want to make sure the transistor isn't drawing current from the Picaxe pin, use a Mosfet. They are voltage driven at the gate, rather than current driven at the base. In other words, unless they are driven quickly, they draw almost unmeasurable leakage current at the gate (picoamps). In other, other words, the moisture on the surface of your circuit may conduct more current than is required to turn the Mosfet on or off.
Search on "logic level Mosfets".
For perspective, a 1 amp hour battery will drive 100 nA for about 10 million hours, or about 1200 years. Back of the napkin calculations.
