Darlington transistor

The Darlington transistor and thyristor should be widely available and not cause concern.

The two heatsinks for the Darlington transistor and diode D1 should also be readily available.

Darlington transistor, a way of connecting transistors.

Darlington transistor is transistor circuit that is made from two transistors.

One drawback of the Baker clamp is its increased low voltage-output level (as in a Darlington transistor).

For equal collector currents, this drawback translates to an increase in the dissipated power for the Darlington transistor over a single transistor.

The Darlington transistor TR1 will get slightly warm, particularly at higher load currents, as will R1 and R22, but otherwise there should be contentment.

Darlington transistors are two BJTs connected together to provide a high current gain equal to the product of the current gains of the two transistors.

Since there are two junctions between the base and emitter of the Darlington transistor, the equivalent base/emitter voltage is the sum of both base/emitter voltages:

The basic Darlington transistor circuit is formed by taking the emitter of the input transistor and connecting it such that its emitter drives the base of the second and then connecting both collectors together.

The tiny junction and stray capacitances between the base and collector terminals of a Darlington transistor, for example, may be drastically increased by the Miller effects due to its high gain, lowering the high frequency response of the device.

In electronics, the Darlington transistor (often called a Darlington pair) is a compound structure consisting of two bipolar transistors (either integrated or separated devices) connected in such a way that the current amplified by the first transistor is amplified further by the second one.
