What is the function of the transistor 2N3055 in the circuit?
The 2N3055 transistor is used as a series pass transistor within linear power supplies and also used in high power and medium-current circuits like DC to AC inverters, low-frequency power converters, audio power amplifiers.
What is the maximum collector current for transistor 2N3055?
The 2N3055 is a power bipolar transistor designed to handle high power loads in the range of 100 V, and 15 amps.
What is hFE in multimeter?
hFE is an abbreviation, and it stands for “Hybrid parameter forward current gain, common emitter”, and is a measure of the DC gain of a junction transistor. So on a multimeter, it indicates a mode where the meter can measure (probably crudely), the HFE of a transistor.
How do you calculate hFE of a transistor?
The common-emitter DC gain (base-to-collector current gain, hFE) is calculated by hFE = IC/IB with VCE at a constant voltage. hFE is also called βF, the forward DC current gain. It is often simply written as β, and is usually in the range of 10 to 500 (most often near 100). hFE is affected by temperature and current.
What is hFE for transistor?
Why do transistors fail?
Failures can be caused by excess temperature, excess current or voltage, ionizing radiation, mechanical shock, stress or impact, and many other causes. In semiconductor devices, problems in the device package may cause failures due to contamination, mechanical stress of the device, or open or short circuits.
How long do transistors last?
Transistors do slowly age as dopants slowly migrate hither and thither, but modern silicon devices are pretty good in this respect, even after 25 years.
Can you fry a transistor?
(Some) Ways to fry a (BJ) transistor: Exceed the base-emitter maximum current rating. Exceed the base-emitter maximum reverse-voltage rating. Exceed the collector-emitter or collector-base maximum voltage rating.
What is the difference between hFE and hFE?
hfe and HFE are two different, but related, characteristics of a bipolar transistor. hFE is the short circuit (vCE=0) forward current ratio (also known as h21) at a specified DC bias (which must be stated for each value of hFE). hfe is the small signal AC gain at a specified bias, and is frequency dependent.
What is the voltage rating of a 2N3055 transistor?
While the voltage rating across the collector and base is 100V DC. Further, the maximum current in the collector pin of the transistor runs at 15A DC. While the maximum voltage across the collector and emitter is 60V DC. The 2n3055 TO-3 case style transistor’s also has a low collector-emitter saturation voltage.
How can we use 2N3055 as a switching device?
The way of controlling power motor via simple push button realizes the use 2N3055 as a switching device and in the same way we can use 2N3055 in other transistor circuits. All measurements are in inches and measurements in brackets are scaled in millimeters

What is the f t of a 2N3055 microcontroller?
Modern 2N3055 datasheets often, but not always, specify f T of 2.5 MHz (minimum) because some improvements have been made over time (especially the move to the epitaxial manufacturing process).
