SSM6J512NU-VB Product details
Back to previous pageProduct introduction：
The SSM6J512NU-VB is a Single P-MOSFET deeply optimized for low-voltage power switching scenarios. The Trench process balances low switching losses with high reliability. The DFN6(2X2) package achieves a balance between thermal dissipation and footprint. The combination of 20V voltage rating, 10A current capability, and 20mΩ on-resistance makes it an ideal cost-effective incremental selection to replace traditional SOP-8 or SOT-23 packaged devices, especially suitable for high-density, high-volume applications.

VDS=-20V: Suitable for 3.3V/5V/12V systems, providing sufficient margin for negative voltage switching application voltage spikes, reducing avalanche breakdown risk.
VGS=±20V: Compatible with 1.8V~12V logic levels, can be directly connected to MCU/PMIC, eliminating the need for level shifting circuits.
Vth=-0.6V (Typical): Can enter the fully enhanced region even with low drive voltage, especially suitable for battery voltage decay scenarios.
RDS(on)=20mΩ @ VGS=10V: Ultra-low on-resistance, significantly reduces temperature rise under full load, can reduce the need for large copper areas for heat dissipation.
ID=-10A: Ample continuous current margin to handle peak demands of most portable and automotive auxiliary loads.
Package DFN6(2X2): Small size, low parasitic parameters, supports high-frequency switching, saves PCB area and assembly costs.
Domain and module applications：
Portable Device Power Management: Low internal resistance improves boost/buck efficiency, extends battery life, small package aids ultra-thin design.
Battery Protection Module: Fast response ensures microsecond shutdown during overcurrent/short circuit, low internal resistance reduces protection board self-heating.
Low-Voltage Motor Drive: Low PWM switching losses, smoother motor operation, significantly reduced controller temperature rise.
Consumer Electronics Control Module: Direct logic level drive simplifies peripherals, suitable for high-volume, low-cost products like smart sockets, USB switches.
LED Lighting Driver: Low conduction voltage drop reduces constant current source power loss, supports multi-channel parallel connection, improving overall luminaire efficacy.
DC-DC Converter: Replaces Schottky diodes in synchronous rectification, heavy-load efficiency can be improved by 2~3%, facilitating module miniaturization.
Automotive Auxiliary Power: Voltage margin and wide operating temperature range suitable for 12V automotive bus, high reliability.
Selection Summary: The SSM6J512NU-VB achieves a balance between performance margin, package size, and system cost. It is a cost-effective general-purpose choice for 20V low-voltage negative voltage switching applications, particularly suitable for projects with strict requirements on space and thermal dissipation.
