**Application fields and examples:** 1. **Power management module:** Due to its high withstand voltage and moderate drain current, BSS84(Z)-VB is suitable for power management modules such as voltage regulators and switching power supplies. 2. **Signal amplifier:** In scenarios where P-Channel MOSFET is required for signal amplification, this transistor can be used in signal amplifier modules. 3. **Current control module:** Due to its low threshold voltage and controllable drain current, it can be used to design current control modules such as current sources or current control switches. 4. **Battery protection:** It can be applied to battery protection modules when it is necessary to protect the battery from overcurrent and overvoltage. Please note that the above examples are for reference only and the actual application may vary depending on the specific design requirements. In design, please always refer to the data sheet and specification notes to ensure correct use and performance.
