SI8283DD-ISR

Isolators - Gate Drivers Overview

The SI8283DD-ISR is a current-output isolated gate driver from the Si828x ISOdriver series, manufactured by Skyworks Solutions. It features an integrated 2W DC-DC converter and utilizes capacitive coupling technology for galvanic isolation with a 5000Vrms rating. The device provides a peak output current of 4A, suitable for driving SiC and IGBT power devices. Key electrical parameters include a maximum propagation delay of 50ns, a minimum common-mode transient immunity (CMTI) of 35kV/µs, and a typical rise/fall time of 5.5ns/8.5ns. It operates within a supply voltage range of 2.8V to 5.5V and functions across a temperature range of -40°C to 125°C.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'ISR' indicates reel packaging when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the manufacturer part number with official Skyworks documentation to ensure authenticity and correct revision history before procurement.

Isolators - Gate Drivers Selection Notes

Select this component for applications requiring integrated power delivery and high-speed isolation. The 4A peak drive capability supports medium-power SiC and IGBT devices. Ensure the 5000Vrms isolation rating meets safety standards for your specific circuit topology. Verify that the 2W internal DC-DC converter suffices for the gate charge requirements of the target power switch.

Isolators - Gate Drivers Part Context

This device belongs to the Si828x ISOdriver family, designed as a modern replacement for traditional optocoupler-based gate drivers. The series emphasizes reduced board space, lower power consumption, and improved long-term reliability compared to legacy technologies. It is engineered specifically for demanding industrial and automotive power electronics environments.

Isolators - Gate Drivers Replacement Considerations

The SI8283BC-IS is listed as a similar alternative within the same product line. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure any replacement maintains the required 5000Vrms isolation and 4A peak drive current specifications.
