BUK1M200-50SGTD,51

Power Distribution Switches, Load Drivers Overview

The BUK1M200-50SGTD is a quad-channel logic level TOPFET power MOSFET manufactured by NXP Semiconductors. It integrates four independent channels within a single 20-pin surface mount plastic package, specifically the SOT163-1 (SO20) form factor. The device utilizes Power TrenchMOS technology to provide robust switching capabilities for low-side driver applications. Key electrical characteristics include 5V logic compatible input levels and integrated protection mechanisms against overtemperature and overload conditions. The component is designed for direct drive by microcontrollers due to its low operating input current.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix '51' against official NXP documentation, as standard datasheets typically list the part as BUK1M200-50SGTD without this suffix. Confirm that the requested variant matches the standard SOT163-1 package and does not imply a different internal configuration or testing grade. Ensure compatibility with existing PCB footprints for SO20 packages when sourcing replacements.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for applications requiring multiple isolated low-side switches in a space-constrained design. It is suitable for driving inductive loads such as motors and solenoids where integrated thermal and overload protection is critical. The 5V logic interface makes it ideal for systems controlled by standard microcontrollers without additional level-shifting circuitry.

Power Distribution Switches, Load Drivers Part Context

The BUK1M200 series belongs to NXP's TOPFET family, which combines power MOSFETs with intelligent protection features. This specific model represents a quad-channel variant, offering a cost-effective alternative to using four discrete single-channel devices. It is part of the broader portfolio of smart power switches designed for automotive and industrial general-purpose switching tasks.

Power Distribution Switches, Load Drivers Replacement Considerations

The BUK1M200-50S DLD is listed as a similar part number in public records. Verify pinout compatibility and thermal performance specifications before substitution. Ensure that any replacement maintains the quad-channel architecture and 5V logic input requirements.
