SOP-4-2.54mm Transistor, Photovoltaic Output Optoisolators ROHS PC817C-S SOP-4_L6.5-W4.6-P2.54-LS10.3-TL LCSC Part Number: C3008369 JLCPCB Part Class: Extended Part Manufactured by UMW(友台半导体) The ESDA18-1K is a transient voltage suppression and electrostatic discharge protection device designed to protect sensitive electronic circuits from ESD events, surge transients, and electrical overstress conditions. Manufactured by STMicroelectronics and commonly used in communication and embedded electronic systems, this device provides fast-response protection for signal lines and low-voltage interfaces exposed to external electrical disturbances. The component utilizes low-capacitance TVS diode technology to clamp transient voltages while maintaining signal integrity on high-speed communication lines. It is optimized for protecting USB interfaces, GPIO lines, communication ports, sensor interfaces, and portable electronic devices from electrostatic discharge damage and transient spikes. The ESDA18-1K is widely used in industrial electronics, consumer devices, embedded systems, communication hardware, and portable equipment requiring compact and reliable ESD suppression. Its small surface-mount package enables easy integration into high-density PCB layouts while improving overall system reliability and EMC robustness. Engineering Specification Device Type Transient voltage suppression and ESD protection diode Protection Function Electrostatic discharge and surge transient suppression Protection Architecture Single-line TVS protection structure Response Characteristics Fast transient clamping response Signal Compatibility Suitable for low-voltage and high-speed signal interfaces Capacitance Characteristics Low capacitance for minimal signal distortion Electrical Performance Low leakage current and stable clamping behavior Reliability Features High ESD robustness and transient tolerance Mounting Style Surface mount technology Package Type Compact SOD-style surface-mount package Thermal Characteristics Low-power passive protection structure EMC Features Enhanced electromagnetic compatibility protection support Applications USB interface protection GPIO protection Communication interfaces Embedded systems Portable electronics Industrial control hardware Sensor interfaces Consumer electronics Signal line protection Data communication systems Manufacturer STMicroelectronics #commonpartslibrary #esdprotection #tvsdiode #transientprotection #signalprotection #stmicroelectronics #embeddedhardware #electronicsdesign
