Key Features
- 100 A continuous drain current rating supports high-current synchronous rectifier and load-switch designs in space-constrained modules
- 25 V VDS breakdown voltage is optimized for 12 V bus converters and 24 V motor-drive applications with adequate safety margin
- 8-pin PDFN package with exposed pad delivers 2.2 W power dissipation without external heatsinks in typical PCB environments
- N-channel enhancement-mode technology provides near-zero gate leakage and straightforward enhancement-mode drive from standard gate driver ICs
Applications
The MCP87018T-U/MF is designed for synchronous buck converter low-side switches and load switches in computing and communications power modules where 12 V rails must supply currents up to 100 A. Its compact DFN footprint and 25 V rating also make it suitable for bidirectional motor-drive H-bridge stages in battery-powered robotics and e-bike controllers operating from 3-cell to 6-cell lithium battery packs. Telecom and server point-of-load regulators benefit from its low on-resistance in multi-phase buck stages targeting sub-1 V processor core voltages.

Frequently Asked Questions
What is the maximum continuous drain current of the MCP87018T-U/MF, and which load-switch scenarios does that enable?
The MCP87018T-U/MF is rated for a maximum drain current of 100 A, enough to act as the primary switch in a 1.2 V, 100 A server processor power stage or as a low-resistance load switch for a 12 V, 80 A bus without paralleling multiple devices. This single-device 100 A capability simplifies BOM and reduces PCB area compared with paralleling two 50 A MOSFETs.
How does the 25 V VDS rating of the MCP87018T-U/MF suit 12 V bus and 24 V motor-drive applications?
For a 12 V bus, the 25 V VDS rating provides roughly a 2× voltage margin above the nominal bus, which is generally sufficient to handle inductive flyback spikes up to about 20 V. In a 24 V motor-drive application the MOSFET sits at the rated limit for steady-state drain voltage, so designs must include gate clamping and careful layout to suppress transients below 25 V. Engineers requiring additional margin in 24 V systems should consider the 30 V rated variant.
What package does the MCP87018T-U/MF use, and how does the exposed pad affect thermal performance?
The device is housed in an 8-pin PDFN (Power DFN) package with an exposed thermal pad on the bottom. When soldered to a 4-layer PCB with 2 oz copper and four thermal vias under the pad, junction-to-board thermal resistance typically reaches around 10 °C/W, allowing the 2.2 W rated dissipation to be handled without an external heatsink at a board temperature of 85 °C.
Is the MCP87018T-U/MF suitable for synchronous buck converter designs targeting 95 % efficiency?
Yes. The MCP87018T-U/MF's combination of low on-resistance and 100 A capability makes it well suited for synchronous rectifier low-side positions in multi-phase buck converters switching at 300 kHz to 600 kHz. At a 12 V input, 1.2 V output, and 100 A total load, a 4-phase converter using this MOSFET in each low-side position can achieve conversion efficiencies above 90 %, with each phase handling 25 A at under 1 mΩ effective switch resistance contribution.
