98-0369PBF

Overview

The Infineon Technologies 98-0369PBF is a high-efficiency, single-channel N-channel power distribution switch designed for general-purpose load control applications. It operates as a high-side switch with a 1:1 input-to-output ratio and features a non-inverting interface. The device supports a maximum continuous output current of 23A and exhibits a typical on-resistance (Rds(on)) of 5.5mΩ. Integrated fault protection mechanisms include adjustable current limiting and over-temperature shutdown to safeguard connected loads. The component is housed in a TO-263-5 (D2Pak) package, providing robust thermal performance for PCB mounting.

Feature Summary

• High-efficiency N-channel power switching architecture
• Integrated adjustable current limiting and over-temperature protection
• Non-inverting logic interface for direct control

Applications

• General-purpose load distribution in industrial systems
• Power management units requiring high-side switching
• Automotive electronic control modules

Procurement Notes

Verify the official product status before procurement, as this specific part number may be classified as obsolete or not recommended for new designs. Confirm that the TO-263-5 package dimensions align with your PCB footprint requirements. Ensure that the 23A current rating and 5.5mΩ on-resistance meet your system's electrical specifications. Cross-reference the latest datasheet from Infineon to confirm pinout compatibility and thermal characteristics for your specific application environment.

Selection Notes

Select this component when a reliable high-side switch with integrated protection is required for moderate current loads up to 23A. The low on-resistance ensures minimal power loss during conduction, contributing to overall system efficiency. Consider the non-inverting input type for straightforward logic interfacing without additional inversion circuitry. Evaluate the thermal dissipation capabilities of the D2Pak package against your enclosure's cooling constraints to ensure safe operation under maximum load conditions.

Part Context

This device belongs to Infineon's portfolio of power management integrated circuits (PMIC), specifically within the power distribution switch category. These components are engineered to replace traditional mechanical relays or discrete MOSFET solutions, offering compact integration and enhanced reliability. The 98-0369PBF utilizes advanced silicon processing to achieve low on-state resistance, distinguishing it from older generation switches with higher conduction losses.

Replacement Considerations

Due to the obsolete status of this part, consult Infineon's official obsolescence notices for approved replacement series. Verify that any substitute maintains the same TO-263-5 package outline and pin configuration to avoid PCB redesign. Ensure the alternative device meets or exceeds the 23A current rating and includes comparable fault protection features such as adjustable current limiting.
