PoE Surge Protection with Diotec's Bipolar TVS Diode Cells and Diode Stacks

Power Over Ethernet (PoE) enabled devices and their associated electronic components can operate over a wide range of applications (e.g., smart signs, vending machines, access surveillance & control, phones, etc.) and, hence, potentially exhibit a wide range of operating currents and voltages that must be reliably protected against transient events.

Diotec Electronics produces standard and custom bipolar (& unipolar) silicon diode cells and diode stacks ideally suited for PoE Transient Voltage Suppression (TVS) applications. Our diode cells and diode stacks provide extremely low electrical and thermal resistance, ensuring a quick response to overvoltage conditions. Diotec's PoE diodes have the ability to effectively dissipate the diode junction heat associated with the conduction of high surge currents during a transient event.

These superior performance characteristics are a result of using an advanced computer controlled vacuum die soldering process which enables silicon chips to be soldered to metal with exception consistency and VOID FREE QUALITY. Thus, Diotec's products have unmatched heat dissipation, cooler junction temperatures, lower leakage currents, and reduced thermal stress. The high quality die attachment allows the diodes to survive mechanical shock without bound failure, a common problem with most offshore "cheap" diodes.

The same vacuum die soldering process is used in "building" a diode stack. All elements in the stack are soldered together at the same time thus ensuring that the same single diode cell qualities described above also the qualities of the completed stack.

All PoE TVS products use ROUND dice, which provide the maxium current carrying capability, which are coupled with Diotec's proprietary vaccuum die soldering technology for maximum heat dissipation and the coolest operating diodes during surge events.

Below are several data sheets which describe rpresentative characteristics of bipolar TVS diode cells which are ideally suited for PoE applications, either as individual diodes or incorporated into TVS diode stacks.

We can tailor breakdown voltages to your specific requirements - one diode or a stack. with your application requirements.
