SLKOR Launches Fully Integrated Smart Low-Side Power Switch SL8402 in Advanced SOT-223 Package

Introducing the next-gen smart low-side switch in compact SOT-223 package - delivering unmatched reliability for industrial/automotive systems.
SLKOR [http://www.slkoric.com] today officially released its new-generation high-reliability smart low-side power switch SL8402 [https://www.slkoric.com/smart-power-switches/558862.html]. The device adopts an innovative SOT-223 surface-mount package, integrating a power MOSFET with multi-protection circuitry and supporting a broad operating frequency range from DC to 10 kHz. With built-in triple protection mechanisms-overtemperature protection, current limiting, and overvoltage protection-the SL8402 can safely drive various resistive, inductive, and capacitive loads, with its driving capability dynamically optimized by maximum power tolerance. This product launch precisely addresses the growing demand for highly integrated power switches in industrial automation, automotive electronics, and smart device applications.

Breakthrough Thermal Management Design

The SL8402's revolutionary thermal shutdown protection technology effectively prevents device overheating caused by overload or inadequate heat dissipation. When the junction temperature exceeds the safety threshold, the chip automatically shuts down the output channel while instantly reporting fault status to the driver circuit via a current surge on the IN pin. Its unique temperature hysteresis control mechanism ensures automatic recovery once temperatures fall below the safety threshold, significantly enhancing system robustness.

Packaging and Performance Advantages

The compact SOT-223 package (6.7 mm times 3.7 mm) seamlessly combines the convenience of surface-mount technology with efficient thermal performance:

Supports automated assembly, substantially reducing manufacturing costs

Optimized lead frame design enables low-inductance connections

Multi-layer thermal paths maximize power density

Effectively avoids performance bottlenecks of traditional PCB heat dissipation routes
