The DALC208SC6-E from STMicroelectronics is a high-quality, bidirectional Transient Voltage Suppression (TVS) diode array designed to protect electronic circuits from electrostatic discharges (ESD) and other voltage-induced transient events. This robust component is ideal for safeguarding sensitive equipment in a variety of applications, including telecommunications, computer interfaces, and other electronic devices that require reliable ESD protection.

Key Features

• ESD Protection: The DALC208SC6-E provides excellent protection against ESD, exceeding IEC 61000-4-2 level 4 standards with an 8 kV (air discharge) and 15 kV (contact discharge) capability.
• Low Capacitance: With a very low capacitance of typically 5 pF per diode, this TVS diode array ensures high-speed signal integrity, making it suitable for protecting high-frequency lines without significant signal attenuation.
• Low Leakage Current: It features a low leakage current, less than 1 µA at the rated voltage, which helps to minimize power consumption and improve the overall efficiency of the protected circuit.
• Bidirectional Protection: The device provides bidirectional clamping, which means it can suppress both positive and negative transient voltages, ensuring comprehensive protection for connected components.
• SOT-23-6L Package: Encased in a small-outline SOT-23-6L package, the DALC208SC6-E is designed for space-constrained applications, offering a compact footprint while still delivering robust protection.
• Multiple Line Protection: This array can protect up to four data or signal lines simultaneously, making it an efficient solution for multi-line protection in a single package.
