Key Features
- Ultra-low 3.4 mΩ (typ.) RDS(on) at 100 V, enabling high-efficiency power conversion with minimal conduction losses
- 110 A continuous drain current and 495 mJ avalanche energy rating for robust motor drive and power supply designs
- STripFET F7 split-gate trench technology balancing low RDS(on) with fast switching for reduced total power dissipation
Applications
The STB15810 is targeted at high-current DC-DC converters, synchronous rectification stages, and motor drive inverters where a 100 V / 110 A N-channel MOSFET with ultra-low on-resistance is required to maximize efficiency. Its D2PAK surface-mount package with an exposed drain pad provides excellent thermal dissipation directly through the PCB, making it ideal for server power supplies, industrial variable-speed drives, and automotive 48V battery management systems. The 495 mJ avalanche energy rating adds design margin in inductive switching environments.

Frequently Asked Questions
What is the typical RDS(on) of the STB15810, and how does it compare to competing 100 V MOSFETs?
The STB15810 achieves a typical RDS(on) of 3.4 mΩ at 100 V with a maximum rated value of 3.9 mΩ, placing it among the lowest on-resistance devices in the 100 V N-channel MOSFET category and reducing I²R conduction losses at 110 A load currents versus conventional trench MOSFETs with 5–8 mΩ RDS(on).
For which 48V or 100V power conversion topologies is the STB15810 most suitable?
The STB15810 is well suited for synchronous buck converters, half-bridge and full-bridge DC-DC stages operating from 12 V to 48 V bus rails, and automotive 48V mild-hybrid inverter switches where the 100 V breakdown voltage provides 2× margin above bus voltage transients and the 110 A rating handles peak inductor currents without derating.
How does the D2PAK package of the STB15810 aid thermal management in a high-current power stage?
The D2PAK (TO-263) package exposes the drain tab as a large top-side copper pad that solders directly to a PCB copper pour, providing a thermal resistance of approximately 0.5°C/W junction-to-case. Combined with an external heatsink or heavy copper pour, this allows the STB15810 to dissipate over 100 W continuously while keeping junction temperature below 150°C at 110 A load.
