NUP4201DR2 is a transient voltage suppressor from Semiconductor Components Industries, LLC. It is designed to protect equipment attached to high speed communication lines from ESD, EFT, and lighting.
The NUP4201DR2 is a transient voltage suppressor (TVS) device featuring an integrated design of surge-rated steering diodes and a TVS diode in an SO-8 package. It is specifically engineered to protect sensitive electronics, such as communications systems and computer peripherals, against damage from electrostatic discharge (ESD), EFT, and lightning on high-speed communication lines.
The device offers three configuration options for protecting up to four data lines: Option 1 uses the positive supply rail (Vcc) as a reference; Option 2 includes bias and power supply isolation using a recommended 10kΩ resistor; and Option 3 utilizes the internal TVS diode as a reference when no positive supply is available. The document also details 'Rail to Rail' protection topologies, comparing discrete diode configurations with the integrated 'RailClamp' concept.
| Peak Power Dissipation (8 x 20 µs) | 500 W |
|---|---|
| ESD Rating IEC 61000-4—2 (Air) | 15 kV |
