Apex Releases SiC Half-Bridge Integrated Power Module: SA111

The SA111 Sets New Standards for High Power and Thermal Management in a Surface Mountable Package with Top-Side Cooling.

Product Overview

Created with Silicon Carbide (SiC) technology and leading-edge package design, the SA111 is expanding the boundaries of thermal efficiency and power density in analog modules. In a surface mount package and with a body of just 20 mm x 20 mm, the SA111 can provide continuous output currents of 24 A (32 A with A-grade variant), manage supply voltages of up to 650 V, and achieve switching frequencies of up to 1 MHz. This thermally efficient package utilizes top-side heat sinking, allowing the user to maximize board layout. The SA111’s Silicon Carbide MOSFETs enable the device to withstand higher thermal stress, managing junction temperatures of up to 175°C. The SA111 SiC power module offers a fully integrated solution allowing for increased device control and protection, featuring an integrated gate driver, under-voltage lockout, and active Miller clamping.

SA111 Typical Application

Silicon Carbide - The Next Chapter of Power Analog Design

The SA111 is the third Apex device that incorporates Silicon Carbide (SiC), a compound material composed of silicon (Si) and carbon (C) that is utilized in the semiconductor industry to gain an efficiency advantage over traditional silicon devices. The durability of Silicon Carbide gives the material increased thermal stability over other devices in its class. Some of the benefits that give Silicon Carbide products the advantage over typical materials can be:

Efficiency Advantages

  • Excellent switching characteristics over wide temperature ranges
  • Reduced power loss compared to silicon or IGBT solutions
  • Lower application/system operating cost

Reduced Heatsinking

  • Compact modules
  • Lighter systems
  • Increased portability

Enhanced Capabilities

  • Increased power delivered
  • Improved reliability
  • Broad operational temperature range
  • Increased voltage supplies
