MCH3383-TL-H

MCH3383-TL-H Description

The MCH3383-TL-H from onsemi is a P-channel MOSFET designed for low-voltage, high-efficiency switching applications. With a drain-to-source voltage (Vdss) of 12V and a continuous drain current (Id) of 3.5A, this device is optimized for power management in compact, space-constrained designs. It features a low on-resistance (Rds(on)) of 69mΩ at 1.5A and 2.5V gate drive, ensuring minimal power loss and improved thermal performance. The MOSFET is housed in an SC70 package, making it suitable for surface-mount applications where board space is limited.

MCH3383-TL-H Features

• Low Gate Charge (Qg): 6.2 nC at 2.5V reduces switching losses, enhancing efficiency in high-frequency applications.
• Low Threshold Voltage (Vgs(th)): 800mV at 1mA enables compatibility with low-voltage logic circuits.
• Fast Switching Performance: Optimized for applications requiring rapid turn-on/off, such as load switches and power distribution.
• Robust Thermal Handling: 1W power dissipation (Ta) ensures reliable operation under moderate thermal loads.
• Compact Form Factor: SC70 package (Tape & Reel) is ideal for automated assembly and high-density PCB layouts.
• Compliance: ROHS3 and REACH unaffected, meeting environmental and regulatory standards.

MCH3383-TL-H Applications

This MOSFET is particularly suited for:

• Portable Electronics: Power management in smartphones, tablets, and wearables due to its low power dissipation and small footprint.
• Battery-Powered Systems: Load switching in Li-ion or NiMH battery packs, leveraging its low gate drive requirements.
• DC-DC Converters: Synchronous rectification or low-side switching in step-down converters.
• Automotive Accessories: Auxiliary power control in infotainment systems or LED drivers, benefiting from its 12V rating.

Conclusion of MCH3383-TL-H

The MCH3383-TL-H stands out for its low Rds(on), compact packaging, and efficient switching characteristics, making it a strong candidate for modern power-efficient designs. While marked as obsolete, its performance metrics remain competitive for legacy or cost-sensitive projects. Engineers should evaluate alternative onsemi offerings for new designs but can rely on this MOSFET for proven reliability in space-constrained, low-voltage applications.
