The P1403EVG is -30V, -11A, P-Channel Logic Level Enhancement Mode Field Effect Transistor.
A P-channel Enhancement-Mode MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of field-effect transistor with P-channel conductivity. This means it uses positively charged carriers (holes) to conduct electrical current.
Enhancement-Mode MOSFETs are typically voltage-controlled devices, and they are called “enhancement-mode” because they require a positive voltage applied to the gate terminal to enhance or enable the flow of current between the source and drain terminals.
Absolute Maximum Ratings (Ta = 25°C)
1. Drain to source voltage: VDSS = – 30V
2. Gate to source voltage: VGSS = ± 25V
3. Drain current: ID = – 11 A
4. Drain Power Dissipation: Pd = 2.5 W
5. Channel temperature: Tch = 150 °C
6. Storage temperature: Tstg = -55 to +150 °C
In a P-Channel MOSFET, a thin layer of oxide is grown on the surface of the p-type substrate, and a metal gate is deposited on top of the oxide.
The gate is separated from the substrate by the oxide layer and is electrically insulated from the substrate.
The gate is used to control the flow of current between the source and the drain terminals of the MOSFET.
