BSS308PEH6327-VB Product details
Back to previous pageProduct introduction：
The BSS308PEH6327-VB is a Single P-MOSFET deeply optimized for low-voltage power switching applications. The Trench process balances low switching losses with high reliability, and the SOT23-3 package balances heat dissipation with board space. The combination of 30V voltage tolerance, 5.6A current capability, and 46mΩ on-resistance makes it an ideal cost-effective drop-in replacement for traditional larger P-Channel devices, especially suitable for high-density, high-volume applications.

VDS=-30V: Suitable for negative power rails, load switches, and battery reverse polarity protection in 5V/12V/24V 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 enhanced region even with low gate drive, particularly suitable for P-Channel load switches in scenarios with battery voltage decay.
RDS(on)=46mΩ @ VGS=10V (54mΩ @ VGS=4.5V): Low on-resistance significantly reduces temperature rise at full load, allowing for reduced copper area for heat dissipation, while also supporting low-voltage logic drive.
ID=-5.6A: 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：
Portable Device Power Management: Low on-resistance improves boost/buck efficiency, extends battery life, small package enables ultra-thin designs.
Battery Protection Modules: P-Channel high-side switch characteristics facilitate overcurrent/short circuit protection, fast shutdown ensures microsecond-level response, low on-resistance reduces self-heating of the protection board.
Load Switches and Power Path Management: In negative voltage or high-side switch applications, low Vth tolerance supports direct control by 1.8V/2.5V logic, simplifying peripheral circuits.
Low-Voltage Motor Drives: Low PWM switching losses, smoother motor operation, significantly lower controller temperature rise.
Consumer Electronics Control Modules: Direct logic level drive simplifies peripheral circuits, suitable for high-volume, low-cost products like smart sockets and USB switches.
LED Lighting Drives: Low conduction voltage drop reduces constant current source power dissipation, supports multi-channel parallel connection, improves overall luminaire efficacy.
DC-DC Converters: Replaces Schottky diodes in synchronous rectification, improving heavy-load efficiency by 2-3%, facilitating module miniaturization.
Automotive Auxiliary Power Supplies: Voltage margin and wide operating temperature range are suitable for 12V automotive bus, offering high reliability.
Selection Summary: The BSS308PEH6327-VB achieves a balance between performance margin, package size, and system cost, making it a cost-effective general-purpose choice for 30V low-voltage P-Channel switching applications, especially suitable for projects with strict space and thermal requirements.
