Working Principle of PMBP27EPAX

The PMPB27EPAX is a MOSFET, which is a type of FET that uses metal-oxide-semiconductor (MOS) technology. This works by the application of a voltage across the drain-source terminals, thus resulting in a channel of electrons being formed in the silicon substrate. This channel is referred to as the “inversion layer”. By varying the voltage on the gate terminal, the conductivity of the channel can be controlled (ie, by controlling the amount of charge carriers present in the channel).A MOSFET can operate in three modes:

• Ohmic: This is the normal mode of operation of a MOSFET device. In this mode, the applied gate-source voltage is low and the channel conductivity is controlled by the drain-source voltage. This mode is used for low-power switching applications.
• Linear: The linear mode is characterized by a high gate-source voltage. This forces the MOSFET into a triode mode of operation, resulting in linear transconductance.
• Saturation: In this mode, the channel conductivity is reaching its maximum and the MOSFET operates in a saturated state. This mode is ideal for high-power switching applications.

Typical Applications of PMPB27EPAX

• DC-DC Converters: The PMPB27EPAX is suitable for use in high-speed DC-DC converters, such as those found in computer power supplies, motor drives, and solar power converters.
• DC-AC Inverters: The PMPB27EPAX can be used as a high-power switch in DC-AC inverters, for applications such as uninterruptible power supplies, switched mode power supplies, and power conditioning systems.
• Consumer, Industrial and Automotive Lighting: Due to its low drain-source ON-resistance and fast switching speed, the PMPB27EPAX is suitable for use in a range of lighting applications, including automotive headlamps, industrial and commercial lighting, and consumer lighting.
