SI83416BDA-IFR

Overview

The SI83416BDA-IFR is a dual-channel isolated smart switch from Skyworks Solutions. It integrates two N-channel power switches with integrated digital isolators, providing galvanic isolation between control and load sides. The device supports a supply voltage range of 2.25 V to 32 V and delivers an output current of 1.25 A per channel. It features a maximum on-resistance of 280 mΩ, ensuring efficient power distribution. The component operates within a temperature range of -40°C to +125°C and is housed in a 32-DFN (9x9 mm) package.

Feature Summary

• Integrates dual high-side and low-side N-channel power switches with digital isolation
• Provides robust galvanic isolation for safe control of high-voltage loads
• Supports wide input voltage ranges suitable for industrial power distribution
• Features compact surface-mount packaging for space-constrained designs

Applications

• Industrial motor control systems requiring isolated switching
• Power distribution units in automation equipment
• Smart grid infrastructure components
• Inverter and converter circuits in renewable energy systems

Procurement Notes

Verify the specific suffix 'IFR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official Skyworks documentation. Ensure the supplier provides genuine parts with traceability. Check for any regional distribution restrictions or lead time variations directly with authorized distributors. Validate that the 32-DFN footprint matches your PCB design requirements before finalizing orders.

Selection Notes

Select this component when dual-channel isolation is required in a single package. Compare against similar models like SI83416BFA if different packaging is needed. Consider the 1.25 A current rating against load requirements. Evaluate thermal performance given the 280 mΩ on-resistance. Verify compatibility with control logic levels and operating voltage ranges for your specific application environment.
