💡 How MOSFETs Work in Mobile Phones | Everything a Technician Needs to Know!

The MOSFET (Metal–Oxide–Semiconductor Field-Effect Transistor) is arguably the most crucial component in controlling power flow on any mobile phone motherboard. If you want to master mobile phone repair and diagnostics, you must understand how these tiny transistors function!

In this essential tutorial, the BTS GSM Team breaks down the theory and practical application of

MOSFETs in mobile devices. We simplify the complex concepts of N-Channel, P-Channel, and how they operate as switches and amplifiers to manage everything from battery charging to circuit protection.

📚 What You Will Learn:
• MOSFET Fundamentals: What it is and why it's essential for mobile electronics.
• The Three Terminals: Understanding the Gate, Source, and Drain.
• Switching vs. Amplification: How MOSFETs perform both roles on the PCB.
• N-Channel vs. P-Channel: Differentiating between the two main types and their uses.
• Practical Application: How MOSFETs are used in charging circuits, power control, and logic switching in modern smartphones.
• Troubleshooting Tips: Identifying common MOSFET failures and diagnosing related issues.
