Product introduction：
PMR290UNE,115-VB is a Single N-MOS deeply optimized for low-voltage, low-power switching applications. Trench technology balances low switching losses with high reliability, and the SC75-3 package achieves a balance between ultra-small footprint and heat dissipation. The combination of 20V withstand voltage, 0.85A current capacity, and 270mΩ on-resistance makes it an ideal cost-reduction upgrade option to replace traditional SOT-23 or larger packages, especially suitable for high-density, ultra-thin, high-volume applications.

VDS=20V: Suitable for 3.3V/5V/12V systems, providing sufficient margin for voltage spikes to reduce avalanche breakdown risk.
VGS=±12V: Compatible with 1.8V~5V logic levels, can directly connect to MCU/PMIC, eliminating the need for level-shifting circuits.
Vth=0.5~1.5V: Fully enters the conduction region under low-voltage drive, especially suitable for battery voltage decay scenarios.
RDS(on)=270mΩ @ VGS=4.5V: Low on-resistance, extremely low loss in low-current applications, no additional heat sink copper foil required.
ID=0.85A: Continuous current sufficient to cover most portable loads, signal switches, and auxiliary power needs.
Package SC75-3: Ultra-small size, low parasitic parameters, supports high-density mounting, significantly saving PCB area and system cost.
Domain and module applications：
Portable Device Power Management: Low internal resistance improves boost/buck efficiency, ultra-small package enables thinner, more compact overall design.
Battery Protection Module: Fast response ensures microsecond-level shutdown during overcurrent/short circuit, low leakage reduces battery energy loss.
Low-Voltage Signal Switch: Logic-level direct drive simplifies peripherals, suitable for GPIO expansion, load switching, and analog switches.
Consumer Electronics Control Module: Suitable for high-volume, low-cost products like smart wearables, Bluetooth earbuds, and electronic cigarettes.
LED Lighting Auxiliary Driver: Low on-voltage drop reduces power consumption, supports multi-channel parallel connection, improving overall lamp energy efficiency.
DC-DC Converter: Replaces Schottky diodes in synchronous rectification or load switches, significantly improves light-load efficiency, facilitates module miniaturization.
Sensor Interface Circuit: Ultra-small package and low-voltage drive characteristics match MCU peripheral signal conditioning, saving main board area.
Selection Summary: PMR290UNE,115-VB achieves a balance between ultra-small package size, low-voltage drive compatibility, and system cost, making it a cost-effective general-purpose choice for 20V low-voltage low-current switching applications, especially suitable for portable products with stringent space and power requirements.
