3. Application fields and module examples

**1. Battery protection system (BMS) **
- **Example**: In the battery management system (BMS), SW601Q-VB can be used as a switching element in the battery protection circuit to protect the battery from overvoltage, overcurrent, etc. MOSFET can be used to disconnect the battery from the load when the battery voltage exceeds the set threshold to prevent the battery from over-discharging or over-charging. Due to its high withstand voltage capability (650V), this MOSFET is suitable for use in the protection circuit of high-voltage battery packs to ensure that the battery operates within a safe range and avoids damage.

**2. High-voltage switching power supply (Switching Power Supply, SPS) **
- **Example**: SW601Q-VB is also suitable for high-voltage switching power supplies, especially in medium and low power applications that need to withstand high voltage. This MOSFET can be used as a switching element to achieve efficient power conversion by controlling the switching frequency of the power supply. Although its on-resistance is relatively high (8400mΩ), it can still provide sufficient performance for 1A current applications and is suitable for some low-power or backup power systems.

**3. Power tools and home appliances**
- **Example**: In the power circuits of some power tools and home appliances, SW601Q-VB can be used for power switching, overload protection, and motor control functions. Especially in situations where high-voltage protection is required but the power requirement is relatively low, this MOSFET can be used as a power switch control element to protect power tools from excessive voltage and achieve stable current control.

**4. Consumer electronics (such as chargers, adapters)**
- **Example**: SW601Q-VB is also suitable for high-voltage switching circuits in consumer electronics such as mobile phone chargers and adapters. In these applications, MOSFET as a switching element can work normally at higher voltages and has good current control capabilities. By using this MOSFET, chargers and adapters can work safely under high voltage conditions to avoid damage to the equipment due to overvoltage.

**5. Automation control system**
- **Example**: SW601Q-VB can be used in industrial automation control systems for functions such as power switching and load control, especially in applications that require high withstand voltage but relatively small current. For example, it can be used as an alternative to relays to control the start and shut down of machines or equipment. In the automation control circuits of industrial equipment, this MOSFET can provide high-reliability current switching functions to ensure safe and stable operation of the equipment.
