MMFTP5618-Q-VB Product details
Back to previous pageProduct introduction：
The MMFTP5618-Q-VB is a Single P-MOSFET deeply optimized for medium and low-voltage power switching applications. Trench technology balances low switching losses with high reliability, and the SOT23-3 package balances heat dissipation with board space. The combination of -60V withstand voltage, -5.2A current capability, and 50mΩ on-resistance makes it an ideal cost-effective drop-in replacement for traditional SOP-8 or SOT-223 packaged devices, especially suitable for high-density, high-volume applications.

VDS=-60V: Suitable for 12V/24V/48V systems, providing ample margin for negative voltage spikes, reducing avalanche breakdown risk.
VGS=±20V: Compatible with 4.5V~12V logic levels, can be directly connected to MCU/PMIC, eliminating level-shifting circuits.
Vth=-1.7V (typical): Can enter the fully enhanced region even with low drive voltage, suitable for battery-powered and load-droop scenarios.
RDS(on)=50mΩ @ VGS=10V: Low on-resistance significantly reduces temperature rise under full load, allowing for smaller heat sink copper areas.
ID=-5.2A: Ample continuous current margin to handle peak demands of most portable and automotive auxiliary loads.
Package SOT23-3: Small size, low parasitic parameters, supports high-frequency switching, while saving PCB area and assembly costs.
Domain and module applications：
Load Switches and Power Management: P-MOS high-side switch solution is simple, low internal resistance reduces voltage drop, improves system efficiency, small package aids compact design.
Battery Protection Modules: Fast turn-off characteristic ensures microsecond-level response during overcurrent/short circuit, low internal resistance reduces self-heating of the protection board.
Low-Voltage Motor Drives: Low PWM switching losses, smooth motor commutation, significantly lower controller temperature rise.
Consumer Electronics Control Modules: Logic-level direct drive simplifies peripheral circuits, suitable for high-volume, low-cost products like smart sockets, USB switches.
LED Lighting Drives: Low conduction voltage drop reduces constant current source power consumption, supports multi-channel parallel connection, improves overall luminaire efficacy.
DC-DC Converters: Replaces P-channel Schottky diode combinations in synchronous rectification, improving heavy-load efficiency by 2-3%, facilitating module miniaturization.
Automotive Auxiliary Power Supplies: Voltage margin and wide operating temperature range adapt to 12V/24V automotive buses, offering high reliability.
Selection Summary: The MMFTP5618-Q-VB achieves a balance between performance margin, package size, and system cost. It is a cost-effective general-purpose choice for -60V low-voltage P-channel switching applications, particularly suitable for projects with strict space and thermal constraints.
