Core Features & Advantages
The PRTR5V0U2X delivers ultra-low capacitance ESD protection for high-speed data lines, combining robust transient suppression with minimal signal integrity impact in a compact SOT-143B package.
- Primary Function: Protects two high-speed data lines or high-frequency signal lines from ESD, EFT, and surge transients by providing low-impedance clamping paths to VCC and GND rails.
- Advantages:
- Ultra-Low Capacitance (1 pF I/O-to-GND, 0.3 pF I/O-to-I/O): Ensures negligible signal degradation on Hi-Speed interfaces such as USB 2.0 (480 Mbps) and HDMI, preserving eye-diagram margins and timing integrity.
- Integrated Additional ESD Protection Diode: An extra diode between GND and VCC prevents supply rail charging during ESD events, guaranteeing signal line protection even when no supply voltage is present — no external capacitors required.
- Very Low Clamping Voltage: Clamps at 16 V max at 2.5 A peak pulse current, well below the damage threshold of most 5 V CMOS ICs, providing a wide safety margin against latch-up and permanent damage.
Typical Application Scenarios
- Industry: Consumer Electronics / Computing / Telecommunications
- Equipment: USB 2.0 ports, HDMI/DVI interfaces, WAN/LAN networking equipment, mobile handsets, notebooks, digital cameras, PDAs
- Use Cases:
- USB 2.0 Port Protection: Placed directly at the USB connector to clamp ESD strikes on D+ and D− lines before transients reach the transceiver IC, with 1 pF capacitance preserving full-speed and high-speed signal quality.
- HDMI/DVI Interface Guard: Protects TMDS data pairs in digital video links where sub-pF parasitic capacitance is critical to maintain impedance matching and minimize bit-error rates at multi-Gbps data rates.
- WAN/LAN System ESD Shielding: Safeguards Ethernet PHY and MAC-side high-speed differential pairs from cable discharge events and electrostatic coupling in enterprise networking equipment.
