Technical Specifications
This device is characterized by its robust performance metrics. It features a GaAs infrared LED optically coupled to a high-speed integrated photodetector. Key electrical specifications include a high isolation voltage of 5,000 Vrms (minimum), which ensures safe operation even in the presence of significant voltage differentials. The optocoupler supports a wide operating supply voltage (VCC) range for the output side, typically from 4.5V to 20V, enhancing its design flexibility.
Its switching performance is a standout feature, with a high-speed data rate capability of up to 1 MBd (Mega Baud), making it suitable for digital signal transmission applications. The propagation delay is typically very low, ensuring minimal signal lag. Furthermore, it operates effectively over an extended industrial temperature range of -40°C to +100°C, guaranteeing reliability in harsh operating conditions. The device is also compliant with international safety standards, including UL, CSA, and VDE.
Application Overview
The primary function of the SS02-0B00-02 is to provide galvanic isolation. This capability makes it indispensable across a wide array of industries.
Industrial Automation and Motor Control: It is extensively used to isolate microcontroller units (MCUs) or digital signal processors (DSPs) from the power stages of motor drives and programmable logic controllers (PLCs). This protects the control logic from high-voltage spikes generated by inverters and motors.
Power Supply Systems: In switched-mode power supplies (SMPS) and uninterruptible power supplies (UPS), this optocoupler is employed for feedback control isolation. It safely transmits feedback signals from the high-voltage secondary side to the primary-side controller, ensuring stable and regulated output voltage.
Data Communication and Interface: Its high-speed capability allows it to be used in digital logic ground isolation and communication interface isolation (e.g., for RS-232, RS-485, and CAN bus), preventing ground loops and data corruption in networked industrial systems.
Medical Equipment: In medical devices where patient safety is paramount, the high isolation voltage provides a critical barrier, isolating the patient-connected parts of the system from the mains-powered sections.
ICGOODFIND: The Broadcom SS02-0B00-02 is a high-performance, high-speed optocoupler that offers robust electrical isolation and noise immunity. Its combination of a high 5kV isolation rating, fast switching speed, and wide operating temperature range makes it an ideal solution for enhancing system reliability and safety in demanding industrial, power management, and communication applications.
