Staying Cool with Smart Tech - Powered by Ultrafast Rectification

As summer heats up, we're reminded how essential cooling systems like refrigerators and air conditioners are. These devices rely on compact and efficient electronics to manage power and temperature, often operating quietly behind the scenes. One key component in these systems is the ultrafast rectifier.

Introducing the UST1G by Diotec, a 1 A / 400 V ultrafast rectifier housed in a low-profile SMAF/DO-221AC package that’s just 1.2 mm high. It's designed for high-frequency, low-power DC/DC converter output stages commonly found in:

  •  Temperature Controllers
  • Industrial Automation
  • Smart Home Devices

With a reverse recovery time of less than 50 ns, the UST1G ensures efficient, high-speed switching and low power loss. It’s ideal for modern, compact designs where Schottky diodes just can't keep up.

Key Features:

  • Ultra-Thin Case Outline
  • 400 V Reverse Voltage Handling
  • Superior Switching Performance

As engineers strive to create smaller, faster, and more efficient power supplies, components like the UST1G are essential building blocks.
