Diodes – High-Voltage Regulators Boost Power Density

The ZXTR1005 family are high-voltage regulators that boost power circuit densities, through reductions in component count and footprint. With the ability to take <100V input and generate a fixed output voltage of 5V±2%, the regulators provide a high-voltage regulation solution where standard linear regulators cannot be used.

These regulators suit 48V DC-DC power system design in telecoms, networking, data storage and PoE, particularly for supplying a regulated voltage into micro-controllers. For samples and quotations please contact your nearest Diodes sales office or representative.

The Diodes’ Advantage

The ZXTR1005 family of devices are series linear regulators using an emitter-follower stage to step down to a 5V±2% regulator.

Smaller footprint

  • Fully integrating this function into a single package (TO252 or PowerDi5060) helps to reduce component count and footprint.

100V Vin

  • High voltage capability means that the input will effectively tolerate spurious voltages up to a maximum of 100V, 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.


Supply regulation in 48V DC:

  • Telecoms
  • Networking & Data Storage
  • Power Over Ethernet (PoE)


  • Fully RoHS compliant
  • “Green” Device
  • ESD rugged
