The ZXTR2000 Diodes family are 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 V DC power system design in telecoms, networking, data storage and PoE, particularly for supplying a regulated voltage into the primary-side, fan or micro controllers.
The ZXTR2000 family of devices are series linear regulators using an emitter-follower stage as the pass-through element.
Smaller footprint
Monolithically integrating a transistor, Zener and resistor into a single package helps to reduce component count and footprint.
100 V 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
Supply regulation in 48 V DC:
- Telecoms
- Networking & Data Storage
- Power Over Ethernet (PoE)
Compliance
- AEC-Q101 qualified
- Fully RoHS compliant
- “Green” Device
- ESD rugged
