Transformer X1 is a 230V primary to 9V-0-9V, 10A secondary used in reverse. 2N3055 - Low voltage NPN power transistor,, STMicroelectronics. Data size calculator Bandwidth converter Download time. Features: DC Current Gain: hFE 20 70 IC 4A CollectorEmitter Saturation Voltage: VCE(sat) 1. Suitable heatsinks may be used for the output stage transistors. The 2N3055 is a silicon NPN transistor in a TO3 type case designed for general purpose switching and amplifier applications. Somewhat higher wattage can be achieved by increasing the drive to 2N3055 transistors (by lowering the value of resistors R7 and R8 while increasing their wattage). This voltage can be used to heat your small electronic devices such as lamp, soldering iron, battery charger etc. When you power the circuit using switch S1, transformer X1 produces 230V AC at its primary terminal. Package: TO-3 Download Newmarket 2N3055 datasheet extracted from 1972/3 product catalogue: Status : NOS (New Old Stock), one for the Newmarket collector, i. ![]() The centre-tapped terminal of the secondary of the transformer is connected to the battery (12V, 7Ah), while the other two terminals of the secondary are connected to the collectors of power transistors T7 and T8, respectively. 2N3055 silicon NPN power transistor by Newmarket transistors ltd. The outputs from the drivers are fed to transistors T5 and T8 (2N3055) connected for push-pull operation.Ī 230V AC primary to 12V-0-12V, 4.5A secondary transformer (X1) is used. 2N3055(NPN), MJ2955(PNP) Preferred Device Complementary Silicon Power Transistors. The complementary outputs from collectors of transistors T1 and T2 are given to PNP darlington driver stages formed by transistor pairs T3-T4 and T6-T7 (utilising transistors BD140 and 2N6107). A easier way to understand it is that the two transistors will start to 'help' the LM317 with current, while the LM317 adjusts the voltage. This starts happening when the IC LM317 is outputting 73mA, as ohms law show us: 0,6/8,2 0,073. For obtaining correct frequency, the values of resistors R3 and R4 may have to be changed after testing. 2N3055 Datasheet : 2N3055(NPN), MJ2955(PNP) Complementary Silicon Power Transistors, 2N3055 PDF VIEW Download ON Semiconductor, 2N3055 1 page Datasheet PDF. The 2N3055 is on a emitter follower configuration and it will supply current to the output of the power supply. Transistors T1 and T2 (BC548) form a 50Hz multivibrator.
