DIY adjustable voltage regulator:
This is the DIY adjustable voltage regulator for 30 volts and 2 amperes. can control the voltage and amperes. Here, use 2 adjustable volumes to control the voltage and amperes. Here, use a 2N3055 transistor. It’s an NPN transistor. We can also use another transistor.
Type Designator is 2N3055. The polarity is NPN. The maximum Collector Power Dissipation is 117 Watts. The maximum Collector-Base Voltage is 100 Volts. the maximum Collector-Emitter Voltage |Vce|: 70 Volts. The maximum Emitter-Base Voltage is 7 Volts. The maximum Collector Current is 15 A.
How to check out the original transistor:
It’s how to check out the original transistor. We have a significant problem identifying the original transistors. Now, there are many fake transistors on the market. For this, we have to face a lot of issues to repair or make electronic circuits. We use the fake one and get problems. We can’t check. It’s not our problem. The problem is the importer. They don’t import the original one.
