STB18NM80 Typical application Circuitry

STB18NM80

STMicroelectronics produced the N-Channel MOSFET STB18NM80 (Metal Oxide Semiconductor Field-Effect Transistor). Electronic signals are switched or amplified using MOSFETs, which are voltage-controlled transistors.

Key Features of STB18NM80: This STB18NM80 device is designed with advanced power MOS technology, which results in a significantly lower on-resistance and high transconductance. With a voltage rating of 800V and a continuous drain current of 17A, this device is perfect for high-efficiency switching applications. Its gate charge is minimized, enabling fast switching performance.

Application Scenarios: The STB18NM80 is commonly used in power applications such as switched-mode power supplies, power factor correction, motor control, and general purpose switching. Due to its high voltage capacity, it can handle demanding power regulation tasks in high voltage scenarios.

Circuit Design

Imagine we are using the STB18NM80 in a simple switched-mode power supply (SMPS) circuit:

1. Drain Terminal: Connect the drain terminal of the STB18NM80 (Pin 2) to the input voltage source. This input voltage will be converted to the desired output voltage.

2. Source Terminal: The source terminal of the STB18NM80 (Pin 3) is connected to the ground (GND). For the other terminals, it acts as a reference point.

3. Gate Terminal: Connect the gate terminal (Pin 1) to the output of a pulse width modulator (PWM). This signal will control the on-off switching of the MOSFET, thus controlling the conversion of the input voltage.

4. SMPS Operation: The STB18NM80 switches on and off according to the PWM signal, converting the input voltage to the desired output voltage. The duty cycle of the PWM signal determines the amount of time the MOSFET is ON, thus controlling the level of the output voltage.

Design Considerations

When designing circuits with the STB18NM80, several key considerations must be made:

- Thermal Management: Make sure the heat generated by the device is efficiently dissipated to prevent overheating and potential device failure.

- Safe Operating Area: Continue to operate within the safe operating area (SOA) designated by the manufacturer.

- Gate Voltage: To prevent causing harm to the device, the voltage applied to the gate must fall within the predetermined range. The STB18NM80 has a gate-source voltage of ±30V.

In essence, the STB18NM80 is a robust N-Channel MOSFET offering a multitude of applications in power regulation and control. It is paramount to consider the operating conditions and safety guidelines when designing circuits with this device to ensure both efficient performance and longevity.
