Overview

Description

PESD2ETH-AXR is a two-channel ESD protection diode array designed for Ethernet interfaces. It protects the Ethernet PHY/transceiver lines by clamping electrostatic discharges to safe levels, helping prevent damage and data errors.
Key features
- 2 protective channels for Ethernet lines (TX+/TX− and RX+/RX− or differential pair)
- Very low input capacitance to minimize impact on high-speed signaling
- Bidirectional ESD diodes to power rails and ground
- Suitable for 3.3V/5V system environments; compatible with common Ethernet PHYs
- Small AXR package footprint for compact designs
- No external power supply required; passive protection
Typical usage
- Place close to the RJ45/magnetic module to protect PHY input/output pins from ESD events
Why use
- Improves robustness and reliability of Ethernet-enabled devices, reducing ESD-induced errors and component failures.
Note
- Check the exact electrical specs (capacitance, clamping voltage, ESD rating) in the official datasheet for your target application.

Features

PESD2ETH-AXR Features (concise)
- 2-channel ESD protection diode array for Ethernet PHY lines (MDI)
- Ultra-low capacitance per channel (to minimize signal loss and preserve high-speed performance)
- Fast response time for transient suppression
- Bi-directional protection to ground
- Suitable for 10/100/1000BASE-T Ethernet interfaces
- Low leakage current and robust ESD performance (IEC 61000-4-2 compliant)
- Compact AXR 6-pin surface-mount package; RoHS-compliant
Note: Specific electrical ratings (capacitance, clamping voltages, and exact ESD levels) are device-dependent—refer to the datasheet for precise numbers.

Package

The PESD2ETH-AXR uses a 6-pin SOT-23-6 (SC-74A) package.

Pinout

Pin count: 6 pins.
Function: A 2-channel ESD protection diode array for Ethernet interfaces; clamps transient voltages to ground on two Ethernet signal lines (protects the Ethernet differential pair).

Manufacturer
