An N-channel MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is a type of field effect transistor (FET) that uses an N-type semiconductor material as the conducting channel to control the flow of current.

When a positive voltage is applied to the gate terminal, it attracts electrons to the channel, creating an inversion layer and allowing current to flow between the source and drain terminals.

N-channel MOSFETs are widely used in a variety of electronic applications due to their high input impedance, fast switching speeds, and low power consumption. They are commonly used as switches, amplifiers, and voltage regulators.

Features :

1. High speed switching

2. Low on-resistance

3. No secondary breadown

4. Low driving power

5. Avalanche-proof

Maximum ratings :

1. Drain-source voltage : VDS = 600 V

2. Continuous drain current : ID = ±13 A

3. Pulsed drain current : ID(puls] = ±52 A

4. Gate-source voltage : VGS = ±30 V

5. Repetitive or non-repetitive : IAR *2 = 13 A

6. Maximum Avalanche Energy : EAS *1 = 216.7 mJ
