The TTK2837 is 500V, 20A, Silicon N Channel MOS Type Field Effect Transistor.

This 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.


1. Low drain-source on-resistance: RDS(ON) = 0.22 Ω (typ.)

2. High forward transfer admittance: |Yfs| = 8.5 S (typ.)

3. Low leakage current: IDSS = 10 µA (VDS = 500 V)

4. Enhancement mode: Vth = 1.5 to 3.0 V (VDS = 10 V, ID = 1 mA)

Absolute Maximum Ratings (Ta = 25°C)

1. Drain to source voltage: VDSS = 500 V

2. Gate to source voltage: VGSS = ± 30 V

3. Drain current: ID = 20 A

4. Drain Power Dissipation: Pd = 280 W (Tc = 25°C)

5. Channel temperature: Tch = 150 °C

6. Storage temperature: Tstg = -55 to +150 °C



1. Switching: N-channel MOSFETs are used as electronic switches in many applications due to their ability to handle relatively high currents and voltages.

2. Amplification: MOSFETs can also be used for amplification purposes in certain configurations.

3. Switching Regulator
