I realize that is a poor excuse, but time is the greatest motivation of all. Complementary silicon power transistors aredesigned for generalpurpose switching and amplifier applications. The only reason I have not done so already is that I am far less familiar with MOSFET specifications than I am BJT's. Now if you come back and say that not only are BJT's inefficient for switching with regards to power dissipation AND they generally are as equally ineffective for switching high currents at high frequencies, then I will stop now and move onto MOSFET's. Base Voltage Collector Current Continuous Base Current Power Dissipation. It is more of an analysis of a coil's output in field strength for varying power input (this stage) as well as pulse frequency and duration (next stage). Continental Device India Limited An ISO/TS16949 and ISO 9001 Certified. This isn't a commercial product I am developing. So if the goal was to get 10 Amps to the coil, and a significant amount of power was dissipated in order to do so (25% give or take), it would be inefficient by today's standards. Please advise regarding any of my assumptions.Ĭost is always a factor, but I assure you that the motivation for this stage of the project is getting a handle on applying the datasheet to proper calculations. I treated the 2V saturation voltage as a voltage drop off the IC output. For now, let'sīase current for saturation with 15A at collector: 15/5 = 3AĬollector current for driving the load: 10.625Aīase current for saturation: 10.625/5 = 2.125Aīase current for saturation with 5A at collector: 5/250 = 20mAĪssuming collector current for driving the 2N3055: 2.125Aīase current for saturation: 2.125/250 = 8.5mAĪssuming collector current for driving the 2N3055: 3Aīase current for saturation: 3/250 = 12mAįor 8.5mA base: R1 = (5v - 2V) /.

My goal is to use the drivers as switches that will ultimately be pulsed so I want the base currents to be correct to assure saturation. Base Emitter Voltage (unsaturated) VCE 4 V dc, IC 4 A dc VBE V dc 1.4 Collector - Emitter Cutoff Current TA +150 oC VCE 100 Vdc VBE -1.

Something I am not sure of is how to properly apply the datasheet information for Collector-Emitter Saturation Voltage for the TIP120. Value Thermal Resistance, Junction to Case 4 R JC 1.5☌/W Parameter Test Conditions Symbol Units Min. I am still learning how to calculate all of this so if possible I would like some help looking over my calculations. When a DC bias voltage is applied across the Emitter-Base (V EB) junction of. The circuit works but I’m not sure that is perfectly ok. A second pair of emitter-coupled transistors receives another current. In the picture you can see that I’m using a 2n2222 that controls a TIP3055 (or a 2N3055). I need to control the speed of a dc motor (0.5 A no load, to 10 A full load).

The driver components I am considering are TIP120 Darlington Transistor driving a 2N3055 Power Transistor. Control DC motor with transistor 2N3055, pwm from Arduino. The output of the IC is 5V with a maximum current of 25mA. I am considering the suitability of some components for driving a high current load from an IC chip.
