Diodes Introduces High-Voltage Regulators for Power over Ethernet

Diodes Incorporated has introduced the ZXTR2000 family of high voltage regulators , which integrate transistors, Zener diodes and resistors into a standard SOT89 package to increase the circuit's power density by reducing the number of devices and footprint. These devices are mainly used in network, telecom and Power over Ethernet applications (Power over Ethernet, referred to as PoE) applications, which can effectively regulate the voltage for 48V DC - DC power supply primary side controller of the transformer .

The ZXTR2005Z, ZXTR2008Z and ZXTR2012Z regulators have a rated input voltage of 48V and a fixed output voltage of 5V, 8V and 12V, giving designers a high-voltage regulator that conventional linear regulators can not provide.

The input and load regulation of these devices ensures the stable operation of the device by preventing the latch-up caused by transient voltage drops. In addition, its unique structure allows the input can effectively withstand the voltage up to 100V, thereby ensuring the application even under transient overvoltage conditions, can also be in the safe range.
