IRLR7833TR

IRLR7833TR Description

The IRLR7833TR is an N-channel HEXFET® power MOSFET from Infineon Technologies, designed for high-efficiency switching applications. With a 30V drain-to-source voltage (Vdss) and 140A continuous drain current (Id), it delivers robust performance in power management circuits. This surface-mount device features an ultra-low on-resistance (Rds(on)) of 4.5mΩ at 15A, 10V, minimizing conduction losses. Its high power dissipation capability (140W at Tc) ensures reliability in demanding environments. Although marked as obsolete, its specifications remain competitive for legacy designs requiring high-current handling in compact packages (DPAK).

IRLR7833TR Features

• Low Rds(on): 4.5mΩ @ 15A, 10V for reduced power loss.
• High Current Capacity: 140A (Tc) continuous drain current.
• Fast Switching: Low gate charge (Qg = 50nC @ 4.5V) and moderate input capacitance (Ciss = 4010pF @ 15V) for efficient high-frequency operation.
• Robust Gate Drive: Supports ±20V Vgs(max), enhancing noise immunity.
• Thermal Performance: 140W power dissipation (Tc) for sustained operation.
• Package: DPAK (TO-252) in tape-and-reel (TR) packaging for automated assembly.

IRLR7833TR Applications

• Power Supplies: DC-DC converters, SMPS, and voltage regulators.
• Motor Control: Brushed/brushless motor drivers in automotive and industrial systems.
• Battery Management: High-current discharge circuits in Li-ion/Pb-acid systems.
• Load Switching: High-side/low-side switches in power distribution units.
• Legacy Designs: Suitable for repairs or upgrades of existing systems requiring high-efficiency MOSFETs.

Conclusion of IRLR7833TR

The IRLR7833TR excels in high-current, low-loss applications, leveraging Infineon’s HEXFET® technology for superior thermal and electrical performance. While obsolete, its low Rds(on), high current rating, and robust packaging make it a viable choice for legacy or cost-sensitive designs. Ideal for power electronics engineers seeking reliability in motor drives, power conversion, and battery systems.
