The ProTek Devices PSOT05C-LF-T7 is an ESD Suppressor TVS 5V 3-Pin SOT-23 T/R that is designed to protect sensitive power-supply lines from electrostatic discharge (ESD) and electrical overstress (EOS). It features an operating voltage of 5V and can handle transient over voltage up to ±30kV. The device also features low junction capacitance, fast response times, and low clamping voltage, making it ideal for high-speed applications such as USB 3.0. In addition, the device has an excellent thermal performance, with low thermal resistances and high peak pulse power. The device is packaged in a SOT-23 T/R configuration, allowing it to be easily mounted onto most PCBs.
