ISSI30R12HXUMA1

Overview

The ISSI30R12HXUMA1 is a solid-state digital isolator from Infineon Technologies, designed for microelectronic relay applications. It features a single channel with unidirectional signal transmission and operates within a supply voltage range of 2.85 V to 3.5 V. The device provides an isolation voltage of 5700 Vrms and supports an operating temperature range from -40 °C to +125 °C. Key electrical parameters include a maximum propagation delay of 20 µs and a typical operating supply current of 16 mA. It is housed in a PG-DSO-33-16 package.

Feature Summary

• Provides high-voltage galvanic isolation suitable for switching applications
• Optimized specifically for driving microelectronic relays
• Features Miller clamping capability for robust operation

Applications

• Microelectronic relay control circuits
• Solid-state isolation interfaces
• High-voltage switching systems requiring compact form factors

Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging and tape-and-reel specifications. Confirm that the required isolation voltage rating of 5700 Vrms aligns with system safety standards. Check the operating temperature range requirements against the specified -40 °C to +125 °C limit. Ensure the supply voltage constraints between 2.85 V and 3.5 V are met by the design power rails.

Selection Notes

Select this component when a dedicated solution for microelectronic relays is required rather than a general-purpose isolator. Consider the specific package dimensions of the PG-DSO-33-16 for PCB layout compatibility. Evaluate the 20 µs propagation delay against the timing requirements of the relay switching application. Verify that the unidirectional channel configuration matches the signal flow direction in the circuit design.

Part Context

This device belongs to the iSSI30RxxH series of solid-state isolators from Infineon Technologies. These components utilize magnetic coupling technology to achieve isolation without optical elements. The series is engineered to replace mechanical relays in certain applications, offering faster switching and longer life cycles compared to traditional electromechanical counterparts.

Replacement Considerations

Check for other variants within the iSSI30RxxH family that may offer different pin counts or isolation ratings if the current specification does not fit the design.
