MTD3055V

MTD3055V Description

The MTD3055V from onsemi is an N-channel power MOSFET designed for high-efficiency switching applications. With a 60V drain-to-source voltage (Vdss) and 12A continuous drain current (Id), it offers robust performance in power management circuits. The device features a low on-resistance (Rds(on)) of 150mΩ at 10V gate drive, minimizing conduction losses and improving thermal efficiency. Packaged in a TO-252-3 (DPAK) surface-mount form factor, it is suitable for space-constrained designs. Although marked as obsolete, its specifications remain competitive for legacy or cost-sensitive applications.

MTD3055V Features

• Low Gate Charge (Qg): 17nC at 10V ensures fast switching, reducing power loss in high-frequency circuits.
• High Input Capacitance (Ciss): 500pF at 25V provides stable gate control, though designers must account for drive requirements.
• Wide Vgs Range: ±20V gate tolerance enhances flexibility in diverse drive circuits.
• Thermal Performance: 3.9W (Ta) / 48W (Tc) power dissipation enables reliable operation under varying thermal conditions.
• Compliance: ROHS3 and REACH compliant, meeting environmental standards.
• Low Threshold Voltage (Vgs(th)): 4V at 250µA ensures compatibility with low-voltage logic drivers.

MTD3055V Applications

• Power Supplies: Ideal for DC-DC converters, SMPS, and voltage regulation due to low Rds(on) and fast switching.
• Motor Control: Suitable for H-bridge drivers and PWM motor drives in automotive or industrial systems.
• Load Switching: Efficient in battery management systems (BMS) and high-side/low-side switches.
• Legacy Designs: Cost-effective replacement for obsolete MOSFETs in maintenance or repair scenarios.

Conclusion of MTD3055V

The MTD3055V balances performance and efficiency, making it a viable choice for medium-power switching applications. While obsolete, its low conduction losses, robust thermal handling, and compliance ensure reliability in existing designs. Engineers should evaluate alternatives for new projects but can leverage this MOSFET for cost-sensitive or legacy systems requiring stable performance. Its TO-252-3 package further simplifies integration into compact layouts.
