What does the arrow mean on a transistor?

The arrow indicates the direction of flow of holes i.e. the direction of conventional current, opposite to the flow of electrons in a transistor.

Where does the arrow point in a transistor?

In npn transistor, current flows out of Emitter and thus arrow head points outward of the emitter and vice-versa in pnp transistor.

What is the schematic symbol for transistor?

Table of transistor symbols

What type of transistor that has an arrow pointing inward on its symbol?

Basically, in this type of transistor construction the two diodes are reversed with respect to the NPN type giving a Positive-Negative-Positive type of configuration, with the arrow which also defines the Emitter terminal this time pointing inwards in the transistor symbol.

What is arrow in MOSFET?

In MOSFETs the arrow is between the gate and the source but it’s not between the drain and source. Current can flow in either direction between drain and source.

Which electrode has an arrow?

5. The NPN transistor always has an arrow pointing out. It is clear that the current directions and voltage polarities in PNPs and NPNs are always opposite to each other. NPN transistors require a power supply with positive polarity with respect to common terminals, but PNP transistors require a negative power supply.

Which electrode is represented with an arrow in a schematic?

The basic schematic symbol for a diode looks like an arrow head that points in the direction of conventional current flow from its Anode (A) terminal to its Cathode (K) terminal. The schematic symbol of a diode also shows that if forward-biased, current will flow through the direction of the arrow.
