Product Overview

CDSOD323-T03C TVS Diode Array is a high-performance semiconductor device designed for electrostatic discharge (ESD) and surge protection. Housed in a compact SOD323 package, it supports bidirectional protection configuration, effectively safeguarding single-line or I/O ports from transient voltage surges. RoHS compliant, the device features low capacitance (3pF typical) and 30kV ESD protection, making it ideal for precise circuit protection in portable electronics.

Key Features

• Bidirectional Overvoltage Protection: Supports dual-direction voltage protection, addressing both positive and negative transient voltage surges to ensure comprehensive circuit safety.
• Superior ESD Protection: Provides up to 30kV ESD protection (HBM mode), complying with IEC 61000-4-2 standards to resist electrostatic interference effectively.
• Ultra-Low Capacitance: With a typical capacitance of ~3pF, it minimizes signal loss, suitable for high-frequency signal lines and ensuring stable data transmission.
• Compact Package Design: Adopts JEDEC-standard SOD323 package (1.60-1.90mm), supporting automated pick-and-place assembly to save PCB space.
• Wide Compatibility: Directly replaces 0805 MLV devices, compatible with various circuit designs to simplify upgrades and reduce material management costs.

Technical Specifications

Typical Applications

• Mobile Communication Devices: Suitable for protecting antenna interfaces and charging ports in smartphones and tablets, resisting daily ESD and surge voltages to ensure signal quality.
• Portable Digital Products: Integrates into sensor interfaces of digital cameras, MP3 players, and GPS devices. Low capacitance avoids high-frequency signal attenuation, ensuring stable data processing.
• Laptops & Peripherals: Protects USB, HDMI, and other I/O ports of laptops from transient overvoltage damage caused by external devices, enhancing device durability.
• IoT Terminals: Ideal for protecting tiny circuits in wearables like smartwatches and wireless earbuds. The compact package fits high-density PCB layouts, balancing protection and miniaturization.
• Industrial Control Interfaces: Provides surge protection for communication ports such as RS-232 and CAN bus in industrial equipment, withstanding harsh environmental EMI to ensure system stability.

Why Choose CDSOD323-T03C?

• Comprehensive Protection: Combines ESD, surge, and overvoltage protection, meeting multiple international standards (IEC 61000-4-2/-4/-5) for all-round circuit safety.
• High-Frequency Friendly: Ultra-low capacitance (~3pF) minimizes signal distortion, suitable for high-speed data interfaces like USB 3.0 and HDMI to ensure lossless transmission.
• Reliability Assurance: Passes wide-temperature testing (-55°C to +150°C) for stable operation in long-term high-temperature environments, with a moisture sensitivity level of 1 requiring no extra 防潮处理 (moisture protection).
• Design Flexibility: Bidirectional protection and SOD323 small package are compatible with surface-mount technology, easy to integrate into space-constrained portable devices or high-density PCBs.
• Compliance & Sustainability: RoHS 2015/863 compliant, lead-free, and halogen-free, meeting global environmental requirements to facilitate quick safety certification.
