IRF5852

FET, MOSFET Arrays Overview

The IRF5852 is a dual N-channel power MOSFET manufactured by Infineon Technologies (formerly International Rectifier). It utilizes advanced processing techniques to achieve extremely low on-resistance per silicon area, providing high efficiency for battery and load management applications. The device features a Dual TSOP-6 package, which houses two independent dies within a compact footprint equivalent to two SOT-23 packages but with reduced board space requirements. This unique thermal design and RDS(on) reduction enable increased current-handling capability compared to single-channel alternatives in similar packages.

FET, MOSFET Arrays Feature Summary

• Dual N-channel configuration integrating two independent MOSFETs in a single surface-mount package
• Ultra-low on-resistance achieved through advanced processing techniques for enhanced efficiency
• Compact Dual TSOP-6 package designed to minimize printed circuit board space consumption
• Low gate charge characteristics supporting efficient switching performance

FET, MOSFET Arrays Applications

• Battery management systems requiring compact dual-switch solutions
• Load management applications where space efficiency is critical
• DC-DC converter designs utilizing small form factor packaging

FET, MOSFET Arrays Procurement Notes

Verify the manufacturer origin carefully, as Infineon acquired International Rectifier. Confirm the specific suffix (e.g., PBF, TRPBF) matches your required tape-and-reel or tube packaging. Ensure the Dual TSOP-6 pinout aligns with your schematic, as it differs from standard single-channel SOIC or SOT-23 layouts. Check for obsolescence status given the legacy nature of the IR brand transition.

FET, MOSFET Arrays Selection Notes

Select this component when dual isolated switches are needed in a minimal footprint. Compare total on-resistance and thermal resistance against two separate SOT-23 devices to validate space savings. Ensure the voltage rating meets the system's maximum drain-source requirements. Verify that the package thermal dissipation capabilities suit the expected continuous current load without excessive heatsinking.

FET, MOSFET Arrays Part Context

This component belongs to the legacy International Rectifier portfolio, now managed by Infineon Technologies. It represents an older generation of dual MOSFET technology designed before the widespread adoption of modern PowerPAK or DirectFET packages. While still functional for general-purpose low-voltage switching, newer Infineon families may offer superior performance density in contemporary designs.

FET, MOSFET Arrays Replacement Considerations

Direct replacements include other dual N-channel MOSFETs in TSOP-6 packages such as the SI4850DY or similar equivalents from Vishay or Diodes Inc. Ensure pin compatibility and electrical ratings match exactly. Consider upgrading to modern dual packages like DFN or QFN if higher performance is required.
