SQ2309ES-T1_GE3-VB Product details
Back to previous pageProduct introduction：
The SQ2309ES-T1_GE3-VB is a Single P-MOS deeply optimized for low-voltage power switching scenarios. The Trench technology balances low switching losses and high reliability, while the SOT23-3 package strikes a balance between heat dissipation and footprint. The combination of 60V voltage rating, -5.2A current capability, and 50mΩ on-resistance makes it an ideal cost-reduction upgrade option for replacing traditional DPAK or SOP-8 packaged devices, especially suitable for high-density, high-volume applications.

VDS=-60V: Suitable for 12V/24V/48V systems, providing ample margin for voltage spikes, reducing avalanche breakdown risk.
VGS=±20V: Compatible with 1.8V~12V logic levels, can be directly connected to MCU/PMIC, eliminating level shifting circuits.
Vth=-1.7V (typical): Can enter the fully conductive region even with low-voltage drive, particularly suitable for battery voltage decay scenarios.
RDS(on)=50mΩ @ VGS=10V: Ultra-low on-resistance, significantly reduces temperature rise under full load, can reduce heat sink copper area.
ID=-5.2A: Ample continuous current margin, can 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：
Portable Device Power Management: Low on-resistance improves buck-boost efficiency, extending battery life; small package aids ultra-thin designs.
Battery Protection Module: Fast response ensures microsecond-level shutdown during overcurrent/short circuit; low on-resistance reduces self-heating of the protection board.
Low-Voltage Motor Drive: Low PWM switching losses, smoother motor operation, significantly lower controller temperature rise.
Consumer Electronics Control Module: Direct drive by logic levels simplifies peripherals, suitable for high-volume, low-cost products like smart sockets and USB switches.
LED Lighting Drive: Low conduction voltage drop reduces constant current source power consumption, supports multi-channel parallel connection, improving overall luminaire efficacy.
DC-DC Converter: Replaces Schottky diodes in synchronous rectification, improving heavy-load efficiency by 2-3%, facilitating module miniaturization.
Automotive Auxiliary Power Supply: Voltage margin and wide operating temperature range are suitable for 12V/24V automotive buses, offering high reliability.
Selection Summary: The SQ2309ES-T1_GE3-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 requirements.
