VDS=100V: Covers 24V/36V/48V system bus voltages, confidently handles inductive load spikes, significantly reducing avalanche breakdown risk.
VGS=±20V: Compatible with 5V~15V drive voltages, can be directly connected to gate drivers or dedicated control ICs, offering high design flexibility.
Vth=1.8V (Typical): Moderate threshold voltage provides strong noise immunity while ensuring full conduction with 10V drive.
RDS(on)=18mΩ @ VGS=10V: Low on-resistance effectively reduces conduction losses, resulting in lower temperature rise under high current conditions, simplifying thermal design.
ID=45A: Ample continuous current capability to meet peak load demands of medium-power motors, battery circuits, and DC-DC converters.
Package TO252: Low thermal resistance, strong power dissipation capability, suitable for power PCB layouts requiring larger copper areas for heat sinking.
Domain and module applications：
Motor Drive Control: 45A high current capability combined with low on-resistance, suitable for power tools, industrial fans, and small robot joint drives. Low PWM switching losses ensure controllable controller temperature rise.
DC-DC Converters: 100V withstand voltage provides ample margin for 48V input buses. Replacing traditional Schottky diodes in synchronous rectification or forward topologies significantly improves heavy-load efficiency, aiding power module miniaturization.
Battery Protection & Management Systems: Fast switching characteristics ensure reliable overcurrent/short circuit protection action. Low on-resistance reduces self-heating of the protection board, suitable for high-cell-count lithium battery packs.
Automotive Auxiliary Power Supplies: Wide withstand voltage range adapts to voltage fluctuations in 12V/24V vehicle electrical systems. High-reliability Trench process meets stringent temperature and vibration environment requirements.
Photovoltaic & Storage Inverters: Used as auxiliary power supply or power switch, withstands photovoltaic panel open-circuit voltage, supports efficient MPPT control, improving overall system energy efficiency.
E-bike & Low-Speed Vehicle Controllers: 100V/45A specifications precisely cover the mainstream power range of 36V/48V controllers. Low on-resistance extends driving range, TO252 package facilitates production assembly.
Industrial Power Supplies & Charging Pile Auxiliary Circuits: High current margin and low thermal resistance design ensure long-term full-load operation, reducing failure rates and maintenance costs.
Selection Summary: DMNH10H028SK3Q-13-VB achieves an excellent balance between withstand voltage level, current capability, conduction loss, and package thermal performance. It is a cost-effective, general-purpose choice for 100V medium-voltage power switching applications, particularly suitable for projects with clear requirements for reliability, high current, and heat dissipation.
