STD30NE06LT4

The STD30NE06LT4 is an insulated-gate bipolar transistor (IGBT) commonly used in switch-mode power supplies and other high-current, high-voltage applications where speed and efficiency are of paramount importance. It is also widely used in motor control, servo-amplifier, IGBT modules and power switching circuits. The device is typically sold in a leaded package and is generally considered to be the industry standard for cost-effective IGBT.

Application Field

The STD30NE06LT4 is designed for use in a variety of medium- to high-power applications requiring tight voltage control and fast switching speed. It is suitable for applications such as motor drives, power supplies, power inverters, battery chargers, and lighting systems. Additionally, the device is suitable for driving large masses such as solenoids and lamps. The STD30NE06LT4 can be used in both switch-mode and linear power supplies, offering a high current-handling capacity and high speeds with very low stand-by power consumption.

Working Principle

The STD30NE06LT4 is essentially a junction field-effect transistor (JFET) with insulated gates. It consists of two types of transistors: an n-channel Metal Oxide Semiconductor (MOS) field-effect transistor (MOSFET) and a p-channel MOSFET. The n-channel MOSFET is the main component and is responsible for switching the device’s output voltage. The p-channel MOSFET is dedicated to providing the necessary gate drive current. When the gate drive of the p-channel MOSFET is activated by a switching circuit, it initiates the current flow through the n-channel MOSFET, which then drives the output voltage depending on the magnitude of the gate drive voltage.

The gate driver current is also responsible for regulating the precise switching times of the device. Thus, as the gate driver current increases, the device’s switching speed increases as well. This makes it possible to achieve lower output voltages with higher accuracy, better efficiency, and faster switching times.

The STD30NE06LT4 is also suited for high-speed switching applications. Its n-channel MOSFET can switch in the sub-nanosecond range due to its low gate-to-drain capacitance. Additionally, its low resistance to gate-to-drain, source-to-drain and source-to-gate capacitance minimizes power dissipation during switching and allows for faster switching times.

In summary, the STD30NE06LT4 is an ideal choice for applications requiring a cost-effective, high-speed and reliable IGBT with tight voltage control and high power-handling capacity. Its n-channel MOSFET and p-channel MOSFET combination ensures that the device can be efficiently and accurately driven, without having to sacrifice efficiency or speed, and its low-power consumption makes it a beneficial solution for high-power applications.
