    1.5 Million x High Gain “Transistor” Sometimes we need a transistor with a different characteristic than the normal one for max voltage and current of the collector, maximum power dissipation and amplification. This can be done by using a combination of complementary transistors connected to work as a single NPN or PNP transistor. In the circuits given here we...
    24V to 36V Battery Charger This 24V to 36V linear battery charger is long overdue. While this is an old circuit technique, it is optimized for charging higher voltage lead-acid battery packs, and could be used on other types of batteries as well. By proper transformer selection, it can be optimized for either 24 or 36V. Note that actual float charge...
    Car Battery Charger with Transistors This car battery charger circuit can be used to charge 12V and 6V batteries. If it is used a transformer that can deliver 4A to 5A at a voltage between 12.6V and 16V then we can get rid of the switch for 6V or 12V batteries. 12V car battery charger circuit schematic car battery maintenance tips The car battery charging current...
    12 Volt Inverter for Soldering Iron Here is a simple 12 V inverter for using a small soldering iron (25W, 35W, etc) in the absence of mains supply. It uses eight transistors and a few resistors and capacitors. Transistors T1 and T2 (each BC547) form an astable multivibrator that produces 50Hz signal. The complementary outputs from the collectors of transistors...
    2N3055 Datasheet 2N3055 is a single diffused NPN silicon transistor in TO 3 case. It is designed for general-purpose switching and amplifier applications. The collector is electrically connected to the case. The 2N3055 transistor is particularly suitable for use in powerfull AF output stages and in stabilized power supply units. 2N3055...
    2N3055 24W Class A Audio Amplifier This a 24 Watt Class A Amplifier circuit made from discrete semiconductors like 2N3055. This audio amplifier can drive up to 24W Class A into 8 Ohm speaker with an audio bandwidth of 100mHz to 100kHz flat. The input power is 305mV for 24W output into 8 Ohm (33dB gain) and the THD is very low. The supply voltage can be between...
