NTD2955G

NTD2955G Description

The NTD2955G from onsemi is a P-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 180mΩ at 10V gate drive, ensuring minimal conduction losses. Packaged in a DPAK (TO-252) surface-mount form factor, it is optimized for space-constrained designs. Although marked as Obsolete, its specifications remain competitive for legacy or cost-sensitive projects.

NTD2955G Features

• High Voltage Handling: Supports 60V Vdss, making it suitable for medium-power applications.
• Low Gate Charge (Qg): 30nC at 10V reduces switching losses, improving efficiency in high-frequency circuits.
• Low Input Capacitance (Ciss): 750pF at 25V enables faster switching speeds.
• Wide Gate-Source Voltage Range: ±20V Vgs(max) ensures compatibility with diverse drive circuits.
• Thermally Efficient: 55W max power dissipation (Tj) with a TO-252 (DPAK) package for effective heat management.
• Reliable for Industrial Use: REACH Unaffected and MSL 1 (Unlimited) moisture sensitivity ensure long-term stability.

NTD2955G Applications

• Power Supplies: Ideal for DC-DC converters, voltage regulation, and load switching due to low Rds(on) and fast switching.
• Motor Control: Suitable for PWM-driven motor drivers in automotive or industrial systems.
• Battery Management: Efficient in reverse polarity protection and discharge control circuits.
• LED Drivers: Low gate charge benefits high-efficiency LED driving applications.
• Legacy Systems: Cost-effective choice for maintaining or upgrading older designs requiring P-Channel MOSFETs.

Conclusion of NTD2955G

The NTD2955G is a well-balanced P-Channel MOSFET offering a blend of voltage tolerance, current handling, and switching efficiency. While obsolete, its low Rds(on), high Vgs tolerance, and robust thermal performance make it a viable option for specific industrial, automotive, and power supply applications. Engineers seeking a reliable, cost-efficient solution for medium-power switching will find value in its specifications, particularly where DPAK packaging and legacy compatibility are prioritized.
