TIP3055 NPN transistor thru put
Posted: Fri Nov 21, 2008 8:14 am
A new IRF510 MOSFET met all the tests:
battery voltage 12.01
volts across the 10 ohm in parallel heaters 10.72
volts across the source and drain 1.19
I also took out the V+ hook up to the gate and pulsed the MOSFET from a 2N2222 and observed 1.9 amps being drawn thru the heaters.
The Mosfet can dissapate 20 Watts. Why would I not use the darlington with a 65 watt dissapation??
Thanks,
Roger
