Skyworks Launches Si86Px Digital Isolators with Integrated Power for Industrial and Automotive Applications

SWKS
April 28, 2026

Skyworks Solutions announced a new family of digital isolators that combine signal isolation with an integrated DC‑DC converter, the Si86Px series. The devices deliver up to 0.5 W of isolated power, 0.1 % typical load regulation, data rates of up to 150 Mbps, a 100 kV/µs CMTI, and operate from –40 °C to +125 °C. The compact package is designed to reduce bill‑of‑materials count and accelerate time‑to‑market for customers in factory automation, advanced driver‑assist systems, and electric‑vehicle power‑management circuits.

The launch aligns with Skyworks’ strategy to broaden its Broad Markets segment, which includes automotive and industrial applications. In the most recent quarter, Skyworks reported revenue of $1.035 billion and non‑GAAP diluted EPS of $1.54, while the prior quarter’s revenue was $1.10 billion with EPS of $1.76. The company’s strong financial performance and the upcoming merger with Qorvo—expected to close in early 2027—provide a solid backdrop for the new product line.

Skyworks’ integrated isolator approach differentiates it from competitors that typically offer separate isolation and power conversion components. By combining these functions, the Si86Px family offers designers a single, space‑saving solution that simplifies circuit design and reduces component count. The product is positioned to meet the growing demand for compact, high‑performance isolation in industrial and automotive electronics, where space constraints and power efficiency are critical.

While the announcement does not include specific market‑size figures or direct quotes from management, the product’s technical specifications and strategic fit suggest that Skyworks is targeting high‑margin, high‑growth segments within its Broad Markets portfolio. The Si86Px launch is expected to support the company’s continued expansion beyond its traditional mobile and IoT businesses, reinforcing its position as a diversified analog and mixed‑signal semiconductor provider.
