Data Sheet Update: ProTek Devices’ PSOT05ULC TVS Array and LC0402FCxxC Flip Chips

pesd1can_prProTek Devices has recently updated data sheets for its PSOT05ULC transient voltage suppressor (TVS) array and its LC0402FCxxC series of flip chips.


The PSOT05ULC is an ultra low capacitance (typically 0.8p) TVS array. This device provides circuit protection for high-speed data transmission interfaces in wired and wireless computing and networking applications. The PSOT05ULC has a working voltage of 5V and offers protection in a SOT-23 package.

This device meets the requirements of IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge). The PSOT05ULC is an ultra low capacitance protection solution for circuits operating at high frequencies and faster edge rates, where insertion loss and signal integrity are serious concerns. General applications for the PSOT05ULC include: high-speed data transmission interfaces; cellular phones; MP3 players; portable electronics; and wireless bus protection.

Other features include a low clamping voltage; 250 Watts peak pulse power per Line (tp=8/20μs); two lines of protection; and RoHS and REACH compliance. Download the full data sheet here.


The LC0402FCxxC series of flip chips employ advanced silicon P/N junction technology. This provides unmatched board-level transient voltage protection against electrostatic discharge (ESD) and electrical fast transients (EFT). Developed specifically for high-density circuit protection, this series meets IEC 61000-4-2 and 61000-4-4 requirements. These devices are ideally suited for handheld devices such as smartphones and other portable electronics, PCMCIA and SMART cards.

This low capacitance series provides ESD protection greater than 25 kilovolts with a peak pulse power dissipation of 200 Watts per line for an 8/20μs waveform. The LC0402FCxxC series also features superior clamping performance, low leakage current characteristics and a response time of less than a nanosecond. Their low inductance virtually eliminates overshoot voltage due to package inductance.

Featuring protection for one line, the series is available in voltages ranging from 3.3V to 36V in a bidirectional and monolithic structure. The series is RoHS and REACH compliant. Download the full data sheet here.
