ISSI30R11HXUMA1

Overview

The ISSI30R11HXUMA1 is a single-channel digital isolator utilizing coreless transformer technology for galvanic isolation. It operates within a supply voltage range of 2.85 V to 3.5 V and supports a maximum insulation voltage of 5700 Vrms. The device features a unidirectional signal path with a typical propagation delay of 6 µs and rise/fall times of 1.9 µs/8 µs. It functions reliably across an extended temperature range from -40 °C to +125 °C. Packaged in a 16-PowerSSOP (PG-DSO-16-33) surface-mount housing, it draws a typical operating current of 16 mA.

Feature Summary

• Coreless transformer technology enables robust galvanic isolation without magnetic cores.
• Integrated protection features include over-current protection (OCP), one-time programmable diode (OTP), and dynamic magnetic coupling (DMC).
• Fast turn-on capability ensures precise timing control for solid-state relay applications.

Applications

• Microelectronic relays and solid-state contactors
• Industrial automation and robotics control systems
• Programmable logic controllers (PLCs)
• Power transmission and distribution equipment

Procurement Notes

Verify the complete part number including the suffix UMA1 to ensure correct tape-and-reel packaging configuration. Confirm that the 16-PowerSSOP footprint matches the target PCB layout. Ensure the design accommodates the specified 5700 Vrms isolation requirements and thermal management needs for operation up to 125 °C. Cross-reference the manufacturer's latest datasheet for any updates on recommended soldering profiles or moisture sensitivity levels.

Selection Notes

Select this component when high-voltage isolation is required for low-speed digital signals in industrial environments. The 6 µs propagation delay suits applications where switching speed is secondary to reliability and isolation strength. Consider the 16-pin PowerSSOP package for its wide creepage distance and thermal performance compared to standard DSO packages. Evaluate the 16 mA supply current against system power budgets for battery-operated or energy-efficient designs.
