Compact package saves space and reduces costs; ultra-low capacitance ensures signal integrity at high data rates

Slkor announces the launch of the SLPESD12VL1BA series electrostatic discharge (ESD) protection diode, which adopts a compact SOD-323 package and is designed for electronic devices requiring efficient transient overvoltage protection. It is suitable for mobile device interfaces, communication system signal links, and computer hardware, including cell phone handsets and accessories, microprocessor-based equipment, Personal Digital Assistants (PDA’s), notebooks, desktops, servers, portable instrumentation, networking and telecom devices, serial and parallel ports, and peripherals. It is particularly ideal for consumer electronics and communication devices with high requirements for protection reliability and space integration.

From interface protection of mobile terminals to signal link protection of communication systems, the SLPESD12VL1BA can effectively resist damage caused by electrostatic discharge (ESD), Cable Discharge Events (CDE), and electrical fast transients (EFT), providing a stable and reliable protective barrier for sensitive circuits.

In terms of protection performance, the diode has passed stringent international standard certifications: it complies with the IEC 61000-4-2 (ESD) standard, with an air discharge protection level of ±15kV and contact discharge of ±8kV, capable of handling transient high-voltage shocks from human electrostatic charges and equipment friction in daily use; in the IEC 61000-4-4 (EFT) test, it can withstand 40A (5/50ns) electrical fast transients, with a peak pulse power of 350 watts (8/20μs waveform), building a solid*for sensitive components on power, data, and transmission lines.

In terms of electrical characteristics, the diode performs excellently: it has a reverse working voltage (V_RWM) of 12V, suitable for low-voltage circuits of most electronic devices; the minimum reverse breakdown voltage (V_BR) reaches 13.3V (test current 1mA), ensuring it remains in a high-impedance state under normal operating voltage without interfering with circuit operation; the maximum clamping voltage (V_C) at 1A current is only 19V, and the maximum clamping voltage at 11A is 32V, which can quickly limit overvoltage to a safe range to avoid damage to backend chips. In addition, its maximum reverse leakage current (I_R) is only 1μA, and the ultra-low power consumption characteristic is suitable for battery-powered devices; the junction capacitance (C_J) is up to 75pF, which has little impact on high-frequency signal transmission, making it suitable for scenarios such as high-speed data interfaces.

In terms of package design, the SLPESD12VL1BA adopts the SOD-323 package, with a compact size (maximum length 1.4mm, width 1.8mm), making it very suitable for miniaturized devices with limited circuit board space. The package uses halogen-free materials, meeting environmental protection requirements, with a flammability rating of UL 94V-0, and can withstand high-temperature soldering at 260℃ for 10s. The 7-inch tape and reel packaging (3,000 pieces per reel) facilitates automated assembly in mass production, and the Moisture Sensitivity Level (MSL) is 1, adapting to different storage environments.

A responsible person of Slkor's protection device product line said: "The launch of SLPESD12VL1BA is our precise response to the increasingly complex electromagnetic environment and miniaturization trend of electronic devices. With its ±15kV ESD protection capability, 12V adaptive voltage, and compact package, it provides efficient protection while meeting engineers' requirements for circuit integration and signal integrity, demonstrating Slkor's technical accumulation in the field of ESD protection. We will continue to optimize our product line to provide global customers with more application-specific protection solutions."
