What is pulsed collector current?

What is pulsed collector current?

The pulsed collector current describes the peak collector current pulse above the rated collector current specification that can flow while remaining below the maximum junction temperature. The maximum allowable pulsed current in turn depends on the pulse width, duty cycle and thermal conditions of the device.

What does continuous collector current mean?

2.4.2. Continuous collector current rating (IC) Nominal continuous collector current (IC) can flow through the device while the case temperature (TC) is held at the specified level, with the junction temperature rising to its maximum ratings due to the dissipated power of the device.

Why IGBT has tail current?

When the IGBT begins to turn off, minority carriers are swept out to external circuitry. When the collector-emitter voltage (VCE) of the IGBT has risen to a certain level (i.e., after the depletion region has expanded), minority carriers contribute to internal recombination current. This current is called tail current.

What is the value of a collector current?

If the transistor in the circuit produces a collector current the value of.03 amps, this represents the fact that the particular transistor in the circuit is acting as a conductor, with a forward bias voltage.

What makes up the collector current in a transistor?

The collector current, along with the base current, is a product of the energy produced through the emitter circuit, which is divided at the base current’s generation through the transistor. Only a fraction of the exiting current is base current, and the remaining portion is considered the collector current.

What is the forward current of an optocoupler?

It consists of collector-emitter voltage (VCE) and collector current (IC) as a function of the base current (IB). With optocouplers, the emitter forward current (IF) is approximately equivalent to the transistor’s base current (IB) and is plotted as forward current (I F) in various steps.
