Overview

The Segger 8.06.02 is a J-Link JTAG Isolator designed to provide electrical isolation between a J-Link debug probe and the target hardware. It protects the debug probe and the development PC from ground loops, high-voltage spikes, and electrical noise commonly found in industrial or power electronics environments. The adapter features dedicated LEDs for power and reset status to simplify hardware debugging.

Why Choose This Part

This adapter provides 1kV of electrical isolation, ensuring that a failure in the target hardware does not destroy the J-Link probe or the host USB port. It maintains signal integrity for JTAG interfaces while offering visual feedback through integrated Power and Reset LEDs.

Applications

High-Voltage Motor Control
Protects the developer and PC when debugging high-power inverter stages where common-mode transients are frequent.
Industrial Sensor Systems
Prevents ground loops from introducing noise into sensitive analog-to-digital conversions during the prototyping phase.
Target-PC Potential Differences
Used when the target hardware and the development workstation are powered from different electrical phases or ground references.

Key Specifications

Accessory Type Adapter Board
Utilized IC / Part Cortex-M Devices

Getting Started

Plug the isolator directly between the Segger J-Link 20-pin ribbon cable and the target board. It requires no additional software configuration and is compatible with any J-Link probe that uses the standard ARM 20-pin 0.1 inch connector. Ensure the target side is powered correctly as the isolator draws its operating power from the target's VCC.
