The DB25-06 part of Diotec is a three-terminal diode protection module designed to prevent overvoltage events on vehicles. It is used in automotive circuit protection applications and features a wide operating voltage of 12V to 50V, allowing for protection in a wide range of conditions. The module incorporates a Zener diode, a TVS diode, and a polyfuse, providing a reliable and cost effective single module device for circuit protection. The polyfuse allows for re-settable circuit protection, while the integrated snubber network gives enhanced protection against voltage transients. The module can be used with a wide range of automotive systems, including body controllers, power supply systems, electronic fuel injection systems and other applications prone to overvoltage events.
