IRLR7833

IRLR7833 Description

The IRLR7833 from Infineon Technologies is a N-channel HEXFET® MOSFET designed for high-efficiency power switching applications. With a 30V drain-to-source voltage (Vdss) and 140A continuous drain current (Id), it delivers robust performance in demanding circuits. The device features an ultra-low on-resistance (Rds(on)) of 4.5mΩ at 15A, 10V, minimizing conduction losses and improving thermal management. Packaged in a DPAK (TO-252) surface-mount form factor, it is optimized for space-constrained designs. Though marked obsolete, its legacy specifications remain competitive for select applications.

IRLR7833 Features

• Low Rds(on): 4.5mΩ @ 15A, 10V ensures high efficiency in power conversion.
• High Current Handling: 140A (Tc) rating supports high-load scenarios.
• Fast Switching: Low gate charge (Qg) of 50nC @ 4.5V reduces drive losses.
• Wide Vgs Range: ±20V gate tolerance enhances compatibility with diverse drivers.
• Thermal Performance: 140W (Tc) power dissipation capability for reliable operation.
• Robust Construction: HEXFET® technology offers low conduction and switching losses.

IRLR7833 Applications

• DC-DC Converters: Ideal for synchronous buck/boost topologies due to low Rds(on).
• Motor Control: Efficient driving of brushed/brushless motors in automotive or industrial systems.
• Power Management: Used in battery protection circuits, load switches, and hot-swap applications.
• UPS/Inverters: High-current handling suits uninterruptible power supplies and inverter stages.

Conclusion of IRLR7833

The IRLR7833 remains a technically compelling MOSFET for high-current, low-voltage applications despite its obsolete status. Its low on-resistance, high current capability, and HEXFET® efficiency make it a historical benchmark for power designers. While newer alternatives exist, its performance in motor drives, power supplies, and energy conversion ensures continued relevance in legacy or cost-sensitive designs. Engineers should evaluate replacement options but may still leverage its proven reliability for specific use cases.
