SI8274AB4D-AM1R

Isolators - Gate Drivers Overview

The SI8274AB4D-AM1R is a dual-channel digital isolator gate driver from Skyworks Solutions, featuring a 2500Vrms isolation rating. It operates within an ambient temperature range of -40°C to +125°C and utilizes a 14-lead DFN package. The device supports high-speed switching with a maximum propagation delay of 105 ns, rise time of 16 ns, and fall time of 18 ns. It provides a peak output current of 4 mA and dissipates up to 1.2 W of power. Designed for industrial applications, it offers low latency and skew characteristics.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'AM1R' indicates tape-and-reel packaging distinct from tray options. Confirm end-of-life status as some listings indicate discontinuation. Ensure compatibility with existing PCB footprints for the 14-DFN package. Validate that the 2500Vrms isolation rating meets system safety requirements. Check for recent product change notifications affecting pinout or materials.

Isolators - Gate Drivers Selection Notes

Select this component when dual isolated channels are required in a compact form factor. The 200 kV/µs CMTI rating suits noisy environments with fast-switching transients. Consider the 14-DFN package for space-constrained designs. Verify input voltage compatibility with the 2.5 V to 5.5 V logic range. Ensure thermal management supports the 1.2 W power dissipation limit.

Isolators - Gate Drivers Part Context

This part belongs to the Si8274 series of galvanically isolated gate drivers. It complements other variants like the SI8274DB4D-IS1 by offering dual-channel capability instead of single-channel. The series targets high-voltage applications requiring robust noise immunity. It serves as a bridge between low-voltage control logic and high-voltage power stages.

Isolators - Gate Drivers Replacement Considerations

Check for direct substitutes within the Si8274 family such as SI8274AB4D-IM1. Verify if single-channel alternatives like SI8274DB4D-IS1 suffice for reduced channel needs. Confirm package compatibility before swapping to SOIC-16 variants. Ensure isolation ratings remain consistent across potential replacements.
