SiA433EDJ-VB Product details
Back to previous pageProduct introduction：
SiA433EDJ-VB is a Single P-MOSFET optimized for low-voltage power switching applications. The Trench process ensures low switching losses and high reliability, while the DFN6(2X2) package balances heat dissipation with board space. With a -20V drain-source voltage rating, -10A continuous drain current, and 20mΩ on-resistance, it serves as an ideal high-density alternative to traditional SOP-8 or SOT23 packages, particularly suited for compact, high-volume applications.

VDS=-20V: Suitable for 5V/12V systems, providing sufficient margin for negative voltage spikes and reducing avalanche breakdown risk.
VGS=±20V: Compatible with 1.8V to 12V logic levels, enabling direct connection to MCU/PMIC without level-shifting circuits.
Vth=-0.6V: Enables turn-on at low drive voltages, suitable for battery voltage decay and low-voltage rail applications.
RDS(on)=20mΩ @ VGS=10V: Ultra-low on-resistance significantly reduces temperature rise under full load, minimizing required copper area for heat dissipation.
RDS(on)=28mΩ @ VGS=4.5V, 40mΩ @ VGS=2.5V: Supports low-voltage drive for enhanced flexibility.
ID=-10A: Ample continuous current margin to handle peak demands of most portable and automotive auxiliary loads.
Package DFN6(2X2): Small footprint, low parasitic parameters, supports high-frequency switching, and reduces PCB area and assembly costs.
Domain and module applications：
Portable Device Power Management: Low on-resistance improves boost/buck efficiency, extends battery life, and small package enables ultra-thin designs.
Battery Protection Modules: Fast response ensures microsecond-level shutdown during overcurrent/short-circuit conditions, while low on-resistance reduces self-heating in protection boards.
Low-Voltage Motor Drives: Low PWM switching losses result in smoother motor operation and significantly reduced controller temperature rise.
Consumer Electronics Control Modules: Direct logic-level drive simplifies peripheral circuits, ideal for high-volume, low-cost products like smart sockets and USB switches.
LED Lighting Drivers: Low conduction voltage drop reduces constant current source power loss, supports multi-channel parallel operation, and improves overall lighting efficiency.
DC-DC Converters: Replaces Schottky diodes in synchronous rectification, improving heavy-load efficiency by 2-3% and facilitating module miniaturization.
Automotive Auxiliary Power Supplies: Voltage margin and wide operating temperature range suit 12V automotive bus systems, ensuring high reliability.
Selection Summary: The SiA433EDJ-VB achieves a balanced trade-off between performance margin, package size, and system cost, making it a cost-effective universal choice for -20V low-voltage switching applications, particularly for projects with strict space and thermal requirements.
