Si8621AB-B-ISR General Description

When it comes to ruggedness, the SI8621AB-B-ISR excels with a wide temperature range of -40°C to 125°C, guaranteeing operation in harsh industrial settings. Furthermore, its low power consumption of less than 4 mA per channel underscores its energy efficiency, contributing to reduced operational costs. Packed in a compact 20-pin SSOP package, this digital isolator is easy to incorporate into space-constrained designs, ensuring flexibility in layout and installation. Notably, its industry-leading electromagnetic compatibility (EMC) performance empowers it to deliver consistent operation even in noisy industrial environments
