ISSI20R02HXUMA1

Overview

The ISSI20R02HXUMA1 is a single-channel digital isolator from Infineon Technologies, utilizing microelectronic relay technology for solid-state isolation. It features an insulation voltage of 5700 Vrms and operates within a supply voltage range of 2.85 V to 3.5 V. The device supports unidirectional signal transmission with a propagation delay of 20 µs. Designed for surface-mount installation in PG-DSO-8 packages, it functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Microelectronic relay-based solid-state isolation technology
• High insulation voltage rating of 5700 Vrms
• Unidirectional single-channel signal transmission
• Wide operating temperature range suitable for industrial environments

Applications

• Digital isolation for microelectronic relays
• Industrial automation systems
• Programmable logic controllers (PLCs)
• Power supplies and power transmission equipment

Procurement Notes

Verify the specific package variant and channel configuration against official datasheets before procurement. Confirm that the ordering suffix matches the required thermal and mechanical specifications. Ensure compatibility with the target system's voltage levels and isolation requirements. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when high-voltage isolation is required for low-speed control signals. The 20 µs propagation delay suits applications where speed is secondary to reliability. Consider the PG-DSO-8 footprint for space-constrained designs. Evaluate the 5700 Vrms rating against system creepage and clearance needs.

Part Context

This device belongs to Infineon’s iSSI series of solid-state isolators, which replace traditional optocouplers using advanced microelectronic relay technology. The series emphasizes long-term stability and reduced size compared to legacy isolation solutions.

Replacement Considerations

Direct substitutes include other iSSI series variants such as ISSI30R11HXUMA1 or ISSI30R12HXUMA1, provided pinout and electrical characteristics align with the design requirements.
