ISSI20R03HXUMA1

Overview

The ISSI20R03HXUMA1 is a digital isolator from Infineon Technologies featuring a single channel with unidirectional signal transmission. It utilizes magnetic coupling technology to provide an insulation voltage of 5700Vrms. The device operates within a supply voltage range of 2.85V to 3.5V and draws a typical operating current of 16mA. It exhibits a propagation delay of 20µs and functions reliably across a temperature range of -40°C to +125°C. The component is housed in an 8-SOIC package (0.295" width) designed for surface mount installation.

Feature Summary

• Employs magnetic coupling technology for solid-state isolation
• Provides high insulation voltage capability for safety-critical applications
• Supports unidirectional data transmission in a compact surface-mount package

Applications

• Power supplies
• Industrial automation
• Programmable logic controllers

Procurement Notes

Verify the specific suffix HUMA1 against the manufacturer's latest documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the target PCB footprint, as the SOIC-8 dimensions must match design constraints. Cross-reference the insulation voltage rating with system requirements to guarantee adequate safety margins for the intended application environment.

Selection Notes

Select this component when a single-channel isolator with high voltage withstand capability is required. The unidirectional nature limits use cases to simple signal transfer rather than bidirectional communication. Consider the 20µs propagation delay when designing timing-sensitive circuits. The wide operating temperature range supports deployment in harsh industrial environments without additional thermal management.

Part Context

This part belongs to Infineon's iSSI series of advanced solid-state isolators. These devices replace traditional optocouplers by using magnetic coupling instead of optical transmission. The series offers improved reliability and performance characteristics suitable for modern industrial and power electronics applications requiring robust galvanic isolation.
