In this video i will show how to make a dc 12v motor speed controller using old CFL lamp this design is not a perfect for other electronic device
About 13005 transistor
Features
High Voltage NPN Transistor
DC Current Gain (hFE) 8 to 40
Continuous Collector current (IC) is 4A
Collector-Emitter voltage (VCE) is 400 V
Collector-Base voltage (VCB) is 700V
Emitter Base Voltage (VBE) is 9V
Base current is 2A (max)
Available in To-220 Package
Because of the high switching voltage and switching current the MJE13005 has a high base voltage of 9V and requires about 2A closing the switching completely when operating across very high voltage. This brings in the need to have a transistor driver circuit for the MJE13005. These are commonly used in SMPS designs along with a switching transformer to switch AC voltage of 115V or 220V at high frequencies.
Since the IC is available in TO-220 format it is relatively simple to use. The transistor has a collector dissipation power of 75W, hence a heat sink will b mandatory when operating at high voltages.
Applications
high current switching (upto 4A) loads
DC-DC Converters
Inverters
Speed control of Motors
Relay/Solenoid driver
