Si8621BC-B-IS Digital Isolator
150 Mbps High-Speed Data meets 3.75 kV RMS Isolation – The Professional Dual-Channel Digital Isolator Silicon Choice for High-Density Industrial Bus Telemetry.
// Ultra-Low Power Core 1 Forward / 1 Reverse Channel Symmetrical 8-Pin SOIC Portfolio
The High-Speed Low-Latency Data Isolation Advantage
The Si8621BC-B-IS represents a premier professional dual-channel digital galvanic isolator solution engineered for space-constrained, high-speed hardware architectures demanding absolute signal processing efficiency and robust noise immunity profiles. Utilizing Skyworks’ proprietary capacitive isolation technology, this module processes up to 150Mbps high-frequency data transmission across 1 forward and 1 reverse directional channels flawlessly without propagation jitter or latch-up hazards. Housed in a standard 8-pin SOIC Narrow Body package footprint, it secures pure, deterministic digital routing and completely cuts off high-voltage ground loop vulnerabilities.
- High-speed data throughput up to 150 Mbps supporting rapid industrial communication interfaces cleanly
- Robust 3.75 kV RMS galvanic isolation rating shielding sensitive MCUs against power bus transients safely
- Optimized channel configuration layout (1/1 bidirectional structure) perfectly matching isolated TX/RX UART architectures smoothly
