Frequently Asked Questions (FAQ)
What are the main features of the diotec-semiconductor N-Channel MOSFET (Part Number MMFTN138)?
The MMFTN138 is a 50V N-Channel MOSFET with a maximum continuous drain current of 220mA, designed for surface mounting in SOT-23-3 packages, offering low Rds On and high power dissipation suitable for various electronic applications.
What is the typical use case for this N-Channel MOSFET in electronic circuits?
This MOSFET is ideal for switching and amplification in low-voltage, low-current applications such as LED drivers, small power switches, and motor control circuits, thanks to its compact SOT-23-3 form factor and reliable performance.
Is the MMFTN138 compatible with standard voltages and driving circuits?
Yes, it operates with a maximum gate-source voltage of ±20V and requires a gate drive voltage of about 4.5V to 10V for optimal Rds On, making it compatible with typical logic-level control signals.
What are the advantages of using this MOSFET in my design compared to other types?
This MOSFET offers a good balance of low Rds On, high operating temperature of up to 150°C, and small package size, which helps improve efficiency and saves space in compact electronic devices.
Does the MMFTN138 come with any warranty or after-sales support, and what is the current stock availability?
The MMFTN138 is in stock with approximately 19,929 units available, and while specific warranty details depend on the supplier, most new original components typically include manufacturer support and standard warranties.
Quality Assurance (QC)
DiGi ensures the quality and authenticity of every electronic component through professional inspections and batch sampling, guaranteeing reliable sourcing, stable performance, and compliance with technical specifications, helping customers reduce supply chain risks and confidently use components in production.
