High-Voltage Linear Regulator Transistors


Diode's ZXTR2000 family of high-voltage transistors tolerate up to 100 VIN

The ZXTR2000 family consists of high-voltage linear regulator transistors that boost power-circuit densities through reductions in component count and footprint. With the ability to take <100 V input and generate a fixed output voltages of 5 V, 8 V and 12 V +/- 10%, the regulator transistors provide a high-voltage regulation solution where standard linear regulators cannot be used. These regulator transistors suit 48 VDC power system design in telecoms, networking, data storage and PoE, particularly for supplying a regulated voltage into the primary-side, fan, or micro controllers.


Features
  • Smaller footprint – Monolithically integrating a transistor, Zener, and resistor into a single package helps to reduce components count and footprint.
  • 100 VIN – High-voltage capability means that the input will effectively tolerate spurious voltages up to a maximum of 100 V, ensuring a good safety margin in the event of transient over-voltage conditions.
  • Line and load regulation – Output voltage is regulated under both line and load fluctuations ensuring the continued supply and preventing latch-up due to transient voltage drops.
Applications
  • Telecoms
  • Networking and data storage
  • Power over Ethernet (PoE)
