IRLMS2002

IRLMS2002 Description

The IRLMS2002 from Infineon Technologies is an N-channel HEXFET® MOSFET designed for high-efficiency switching applications. With a 20V drain-to-source voltage (Vdss) and 6.5A continuous drain current (Id), this surface-mount MOSFET is optimized for low-voltage, high-current operations. It features a low on-resistance (Rds(on)) of 30mΩ at 4.5V Vgs, ensuring minimal power loss and improved thermal performance. The device is housed in a MICRO6 package, making it suitable for space-constrained designs. Although marked as obsolete, its robust performance metrics make it a viable choice for legacy or low-power systems.

IRLMS2002 Features

• Low Gate Charge (Qg): 22nC at 5V Vgs enables fast switching, reducing switching losses in high-frequency applications.
• Low Input Capacitance (Ciss): 1310pF at 15V minimizes gate drive requirements, enhancing efficiency.
• Wide Drive Voltage Range: Operates efficiently at 2.5V to 4.5V Vgs, making it compatible with low-voltage logic circuits.
• High Power Dissipation: Supports 2W (Ta) power dissipation, ensuring reliable thermal management.
• Robust Protection: ±12V maximum Vgs rating provides overvoltage protection for gate drive circuits.
• REACH Unaffected & MSL 1: Compliant with environmental regulations and suitable for extended storage.

IRLMS2002 Applications

• DC-DC Converters: Ideal for synchronous buck/boost converters due to low Rds(on) and fast switching.
• Power Management: Efficiently used in battery-powered devices, portable electronics, and load switches.
• Motor Control: Suitable for low-voltage motor drivers in robotics and automotive subsystems.
• LED Drivers: Enhances efficiency in LED backlighting and driver circuits.
• Consumer Electronics: Fits into compact designs like smartphones, tablets, and wearables.

Conclusion of IRLMS2002

The IRLMS2002 offers a balance of low on-resistance, fast switching, and compact packaging, making it a strong candidate for low-voltage power applications. While obsolete, its HEXFET® technology ensures reliable performance in legacy systems. Engineers seeking a cost-effective, space-saving MOSFET for DC-DC conversion or motor control may still find value in this component. For newer designs, Infineon’s updated MOSFET series may provide enhanced features, but the IRLMS2002 remains a proven solution for specific use cases.
