STMicroelectronics 2-Channel Channel Protector 3.6V, 16-Pin QFN CLT03-2Q3

STMicroelectronics CLT03-2Q3 is a high-performance 2-channel channel protector designed for robust overvoltage and current protection applications in electronic circuits. It operates at a maximum supply voltage of 3.6V and is housed in a compact 16-pin QFN (Quad Flat No-lead) surface mount package measuring 4.05mm in length and 950μm in height.

This device requires no external power supply, being powered through its inputs, which enables reduced PCB complexity and enhanced integration flexibility. Its digital input current limiting ensures circuit safety by automatically restricting excessive currents, improving system reliability. The integrated glitch filter enhances immunity against electromagnetic interference, making it suitable for applications demanding high EMC robustness.

The CLT03-2Q3 is compatible with both high side and low side configurations as well as reverse plug-in compatibility, supporting diverse circuit design requirements. It can directly drive opto-couplers or 3.3V LVTTL circuits, offering versatile interface options.

Designed for a wide operating temperature range from -55°C to 150°C, this device meets rigorous industrial and automotive environment conditions, although it does not carry specific automotive approval standards. Its maximum overvoltage protection capacity extends up to 60V while maintaining a low maximum leakage current of 10μA to prevent unnecessary power loss.

Provides 2 isolated channels for overvoltage protection. Operates without external power, powered via input signals. Surface mount QFN 2x4 16L package ensures compact design. Digital input current limitation protects sensitive circuits.

Glitch filter for enhanced electromagnetic compatibility. Wide operating temperature range suitable for industrial use. High side, low side, and reverse plugin compatible. Directly drives opto-coupler or 3.3V LVTTL output circuits.

Maximum overvoltage protection of 60V. Low leakage current of 10μA conserves energy.

Ideal for protecting digital inputs in industrial, automotive, and consumer electronic applications, this component ensures system reliability by guarding against voltage spikes and input current anomalies. Its compact package and versatile mounting make it suitable for modern PCB designs demanding space efficiency and robust performance.
