SI8261BCC-C-IP

Isolators - Gate Drivers Overview

The SI8261BCC-C-IP is a single-channel isolated gate driver from Skyworks Solutions, designed as an opto-driver replacement. It utilizes capacitive coupling technology to provide 3750Vrms isolation voltage. The device features a peak output current of 4A with high-side and low-side drive capabilities. Key electrical parameters include a minimum common-mode transient immunity of 35kV/µs, maximum propagation delays of 60ns (tpLH) and 50ns (tpHL), and typical rise/fall times of 5.5ns and 8.5ns respectively. It operates within a supply voltage range of 6.5V to 30V and supports temperatures from -40°C to +125°C.

Isolators - Gate Drivers Procurement Notes

Verify component authenticity through authorized Skyworks distributors or certified partners. Confirm the specific suffix 'C-IP' matches the required PDIP-8 package variant. Check for recent Product Change Notifications (PCN) regarding lifecycle status, as this part may be subject to obsolescence notices. Ensure compliance with AEC-Q100 automotive qualification requirements if applicable to the target application environment.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated driver with 4A peak current is required. It is suitable for applications needing high common-mode noise rejection and fast switching speeds. Consider the PDIP-8 package for through-hole mounting needs. Evaluate against other Si826x variants if dual-channel operation or different isolation voltages are necessary for the system design.

Isolators - Gate Drivers Part Context

This device belongs to the Si826x family of isolated gate drivers from Skyworks Solutions. The family leverages silicon dioxide (SiO2) insulation technology to replace legacy optocouplers. The SI8261BCC-C-IP specifically represents the single-channel, through-hole DIP variant within this portfolio, offering enhanced reliability and performance metrics compared to older isolation technologies.
