Key Features
- High-voltage N-channel MOSFET with 550 V minimum drain-source breakdown voltage for robust operation in power conversion circuits
- Low on-resistance of 0.21 Ω maximum at 14 A drain current, minimizing conduction losses for improved efficiency
- Integrated built-in body diode in compact DPAK-3 (TO-252) surface-mount package enabling simplified PCB design for synchronous rectification
Applications
The STD18N55M5 is designed for high-voltage power switching applications such as switch-mode power supplies, PFC (power factor correction) stages, and motor drive circuits. Its 550 V breakdown rating and low RDS(on) of 0.21 Ω make it suitable for off-line AC-DC converters and DC-DC boost converters operating from mains-derived voltages. The DPAK surface-mount package facilitates automated PCB assembly in compact power electronics designs.
