The SP78LC30EM5/TR is a low capacitance TVS (Transient Voltage Suppression) diode array designed for protecting sensitive electronic components from ESD (Electrostatic Discharge), EFT (Electrical Fast Transients), and lightning-induced surges. Manufactured by Sipex Corporation (now part of MaxLinear), this device is ideal for safeguarding data lines and I/O ports in various electronic systems.

Applications

• Protection of USB ports
• Protection of Ethernet ports
• Protection of HDMI ports
• Protection of RS-232/RS-485 interfaces
• Protection of sensitive data lines in consumer electronics

Features

• Low capacitance for high-speed data transmission
• Provides protection against ESD, EFT, and surge events
• Low clamping voltage for effective protection
• Small footprint package (typically SOT-23-5 or similar)
• RoHS compliant

Benefits

• Ensures reliable data transmission in high-speed interfaces due to low capacitance.
• Protects sensitive electronic components from damage caused by ESD, EFT, and surge events, increasing system reliability.
• Limits voltage spikes to safe levels, preventing damage to protected circuitry due to low clamping voltage.
• Saves board space due to the small footprint package.
• Complies with environmental regulations due to RoHS compliance.

Technical Specifications

The SP78LC30EM5/TR typically features a low capacitance of around 0.5pF to 2pF, making it suitable for high-speed data lines. It can withstand ESD strikes up to ±30kV (air discharge) and ±30kV (contact discharge) according to IEC 61000-4-2. The clamping voltage is typically in the range of 5V to 10V at a specific surge current. It's commonly available in a SOT-23-5 or similar small surface mount package.
