HCPL-9031-500

Overview

The HCPL-9031-500 is a high-speed digital isolator from Broadcom Limited, featuring two independent channels with unidirectional signal transmission. It utilizes magnetic coupling technology to provide an isolation voltage of 2500 Vrms and supports data rates up to 110 MBd. The device exhibits a common-mode transient immunity (CMTI) of 15 kV/µs and typical propagation delays of 15 ns. Designed for surface-mount applications, it is housed in an 8-SMD, Gull Wing package. Operating temperatures range from -40°C to +100°C, ensuring reliability in demanding industrial environments.

Feature Summary

• High-speed data transmission capability supporting up to 110 MBd
• Robust noise immunity with 15 kV/µs common-mode transient rejection
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power electronics control circuits

Procurement Notes

Verify the specific suffix '500' against official Broadcom documentation to confirm the exact reel quantity and tape specifications. Ensure compatibility with existing PCB footprints for the 8-SMD Gull Wing package. Confirm that the component meets all required environmental standards for the intended deployment region before finalizing procurement orders.

Selection Notes

Select this component when high-speed digital isolation is critical alongside strong noise immunity. The 110 MBd rate suits fast communication protocols, while the 15 kV/µs CMTI protects against electrical noise. Consider the SMD form factor for automated assembly processes and verify power supply voltage ranges match the system requirements.

Part Context

This part belongs to the HCPL-90xx series of high-speed digital isolators manufactured by Broadcom Limited. These devices are engineered for applications demanding fast signal transfer across isolation barriers. The series leverages magnetic coupling technology to achieve high performance in a compact footprint, serving as a key interface solution in modern electronic systems.

Replacement Considerations

Check for direct substitutes within the HCPL-90xx family or equivalent products from other manufacturers offering similar isolation voltages and data rates. Verify pinout compatibility and package dimensions to ensure seamless integration without redesigning the printed circuit board layout.
