PESD2ETH1G-TR

PESD2ETH1G-TR is a two-channel ESD protection diode array targeted at 1000BASE-T Ethernet interfaces. It protects the Ethernet PHY pins on differential lines by clamping electrostatic discharges to supply rails or ground, helping prevent damage from ESD events.
Key points:
- Two protection channels designed for Ethernet differential pairs (1 Gbps).
- Very low channel capacitance to minimize impact on signal integrity.
- High ESD withstand capability with fast response.
- TR suffix = Tape & Reel packaging for automated assembly.
Typical use: place close to the Ethernet PHY or near the RJ45 connector on a board to protect transceivers and maintain reliability in consumer, industrial, or networking equipment. Always consult the datasheet for exact ESD ratings, capacitance, and recommended PCB layout.

PESD2ETH1G-TR is a 2-channel ESD protection device for Ethernet interfaces. Key features:
- 2-channel protection for Ethernet data lines (suitable for 1G/1000BASE-T)
- Ultra-low parasitic capacitance to preserve high-speed signal integrity
- Bi-directional ESD protection diodes to ground
- Fast response time to clamp ESD transients quickly
- Robust ESD capability per IEC 61000-4-2 (high-energy withstand)
- Low leakage current
- Wide operating temperature range (typical -40°C to 125°C)
- Tape & Reel packaging (-TR) for automated assembly
Note: exact clamp voltages and capacitance values vary by variant; check datasheet for precise specifications.

PESD2ETH1G-TR is a 3-pin device (SOT-23 style): Pin 1 = I/O1, Pin 2 = GND, Pin 3 = I/O2. Its function is a low-capacitance ESD/surge protector for one Ethernet differential pair (two signal lines), clamping ESD/transient pulses to ground while preserving signal integrity for high-speed (1 Gbps) Ethernet.

Manufacturer: Nexperia.
