IRF840ALPBF application field and working principle

IRF840ALPBF is an Insulated-Gate Bipolar Transistor (IGBT) manufactured by International Rectifier. This IGBT is ideal for high efficiency, low noise power conversion in various applications, including power supplies, motor control, lighting, renewable energy and telecom systems. It is a high voltage, high current device with wide operating temperature range from -40°C to 175°C.

IRF840ALPBF is a N-channel depletion-mode MOSFET device with high power, high current capabilities and high frequency operation. It offers very low on-state resistance (RDS(on)) and fast switching speeds at operating voltages up to 1,000V. The device has a drain-source breakdown voltage of 850V, a gate-source threshold voltage of 2.5V and a gate-drain “ Miller ” capacitance of 0.8pF. It is housed in a TO-220, isotropic surface-mount (ISOP) package and is made with a copper base-plate to provide excellent thermal conductivity and better heat dissipation.

IRF840ALPBF works by controlling the amount of current flowing through the transistor and hence controlling power consumed. When a gate voltage is applied to the Gate terminal, the current crosses the threshold voltage and the MOSFET switches and allows current to flow through the Drain-Source line. The transconductance is increased by increasing the gate voltage and the amount of current that can be controlled depends on the level of voltage applied to the Gate. When the Gate voltage is less than the threshold voltage, the current stops flowing through the transistor and in this way, power to the load is controlled.

Because of its broad power conversion capabilities, IRF840ALPBF can be used in many applications, including:

• Power supplies
• Motor control
• Power converters
• Lighting
