The MDD1903 uses advanced MagnaChip’s MOSFET Technology, which provides high performance in on-state resistance, fast switching performance and excellent quality. MDD1903 is suitable device for DC/DC Converters and general purpose applications.

A 100V, 11A, Single N-channel trench MOSFET is a specific type of power MOSFET designed for switching and amplifying electrical signals in electronic circuits. Here are the key details about this type of MOSFET:

1. Voltage Rating: The MOSFET has a maximum voltage rating of 100 volts (V), which means it can withstand voltages up to 100V without breaking down or sustaining damage.

2. Current Rating: The MOSFET is rated to handle a maximum continuous drain current (ID) of 11 amperes (A). This specifies the maximum current that the MOSFET can safely carry under specified operating conditions.


1. VDS = 100V

2. ID = 11A @VGS = 10V

(1) < 120mΩ @VGS = 10V
(2) < 135mΩ @VGS = 6.0V

N-channel trench MOSFETs are commonly used in a wide range of applications, including power supplies, motor control, voltage regulation, and power switching circuits. They offer low on-resistance (RDS(on)) and fast switching characteristics, making them suitable for high-frequency and high-power applications.

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 = 11 A

4. Power Dissipation: Pd = 39 W

5. Channel temperature: Tch = 150 °C

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