Re: MOSFET Question

hello all, I'm going to REPLACE the momentary switch with P-chann enhanced MosFet or the NPN Darlington. Which ever is cheaper and can handle the current less then 1 Amp. 5vdc. I will only activate this device 3 times within 90 sec.(Once every 30 sec.) for 2-3 sec max., this will simulates the pushi...

Re: MOSFET Question

Thanks for the quick reply, My intent is to replace a push button switch(momentary) with a transistor or P-chann. From the BS2 5vdc would turn on the switch(2-3 sec.) simulating the push button switch. Both parts I looked at are rated at 5vdc 1.5 amp. When I talked to the makers of the Test unit all...

Re: MOSFET Question

Hello to All, First time on this Forum, Your Question is Almost exactly what I'm doing. I'm getting back into electronics and will take any and all advice. I want to replace a momentary switch(2 -3 sec. push time) with an electronic switch(P-chan. Mosfet - or - Mouser 512-NZT605 NPN). I learned that...
