Description

K2962 is 100V, 1A, N-channel MOSFET(Metal Oxide Semiconductor 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.

Features

1. 4-V gate drive

2. Low drain−source ON resistance : RDS (ON) = 0.5 Ω (typ.)

3. High forward transfer admittance : |Yfs| = 1.2 S (typ.)

4. Low leakage current : IDSS = 100 μA (max) (VDS = 100 V)

5. Enhancement mode : Vth = 0.8~2.0 V (VDS = 10 V, ID = 1 mA) […]

Absolute Maximum Ratings (Ta = 25°C)

1. Drain to source voltage: VDSS = 100 V

2. Gate to source voltage: VGSS = ± 20 V

3. Drain current: ID = 1 A

4. Drain Power Dissipation: Pd = 0.9 W

5. Channel temperature: Tch = 150 °C

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

Applications:

1. Chopper Regulator

2. DC−DC Converter and Motor Drive
