SFW9Z34TM-VB Product details
Back to previous pageProduct introduction：
SFW9Z34TM-VB is a Single P-MOS optimized for medium and low voltage power switch scenarios. The Trench process balances low conduction losses with high switching reliability, and the TO263 package achieves a good balance between high-current heat dissipation and PCB soldering processes. The combination of 60V withstand voltage, -30A current carrying capacity, and 64mΩ on-resistance makes it a cost-effective choice for high-side switches, power conversion, and load management applications, especially suitable for systems requiring simplified low-side drive or negative power rail control.

VDS=-60V: Suitable for 12V/24V/36V systems, provides ample margin for negative voltage spikes, reduces avalanche breakdown risk, ideal for industrial and automotive bus environments.
VGS=±20V: Compatible with wide gate drive range, supports standard logic levels and dedicated gate drivers, simplifies interface design.
Vth=-1.7V (Typical): Low threshold voltage allows full conduction with moderate drive voltage, facilitating P-channel control in battery-powered applications.
RDS(on)=64mΩ @ VGS=10V, 77mΩ @ VGS=4.5V: Low on-resistance minimizes full-load losses, effectively reduces power device temperature rise, and allows for smaller heatsinks.
ID=-30A: Ample continuous current margin covers peak current requirements for most motors, solenoids, and power switches.
Package TO263: Low thermal resistance, high current capability, suitable for medium-power surface mount designs, balancing thermal performance and automated production efficiency.
Domain and module applications：
High-side Load Switch: P-MOS naturally suits source-follower high-side drive, simplifying control circuits and reducing static power consumption, widely used for power reverse polarity protection and load switching.
Battery Protection Board: The voltage withstand and low on-resistance ensure a small voltage drop in the discharge loop, with fast response during overcurrent/short circuit, enhancing battery pack safety.
Low-voltage Motor Drive: Low PWM switching losses, combined with a dedicated driver, enable smooth control of motor direction and speed, suitable for power tools, water pumps, and fans.
Power Conversion and DC-DC: Used as the main switch in buck or inverting topologies, low conduction losses help improve overall conversion efficiency.
Automotive Auxiliary Circuits: The 60V voltage margin suits 12V/24V automotive systems, and the wide operating temperature range and robust package meet engine compartment and chassis application requirements.
Industrial Control Modules: Used in PLC output interfaces, solenoid valve drives, and power stages after signal isolation, offering high reliability and long life. Selection Summary: SFW9Z34TM-VB achieves a balance between voltage withstand, current capability, on-resistance, and package heat dissipation. It is a cost-effective, general-purpose choice for 60V P-MOS power switch applications, especially suitable for projects with clear requirements for negative voltage control, high current switching, and thermal reliability.
