Trench varistors (TVSs) are non-linear, bidirectional voltage suppressors designed to limit transients up to 5.0 kV. With their superior surge suppression capability, these devices are at the heart of current protection circuits. TVSs are widely used to protect against fast, destructive current transients in power and communication systems. Additionally, they provide some of the best surge protection against lightning and EMI for modern applications.

The 5.0ST5G Series Transient Voltage Suppressor (TVS) Diodes from STMicroelectronics are high-power, ultra-fast, non-linear voltage-clamping components designed for transient overvoltage protection. They are designed for applications in consumer, industrial and automotive electronics.

The 5.0ST5G Series offers a wide operating range from 45V to 270V with an ultra-wide clamping range up to 5.0 kV. This device also offers high-current handling capacity up to 12 A peak pulse current. With a fast response time of less than 1 nanosecond, the device is suitable for data lines that require fast and reliable protection for high-speed interface applications.

The device also features low parasitic capacitance, which is ideal for protecting high-speed data lines, such as USB3.0, HDMI and Ethernet. It also has a low operating and clamping voltage, low leakage current and low thermal resistance, making it ideal for a variety of applications. The device is UL Recognized and has zinc-oxide varistors with superior surge current handling capabilities.

The 5.0ST5G Series TVSs provide excellent protection from transients and ESD on sensitive electronic components. The device works by clamping the voltage across the device during an overvoltage event. During normal operating conditions, the parasitic capacitance of the device provides electrical isolation between the device and the circuit. The ultra-wide clamping range ensures that the voltage across the device remains low, while still allowing the circuit to operate within the proper voltage range.

The 5.0ST5G Series TVS Diodes are ideal for automotive and industrial applications such as DC-DC converters, bus systems, and power supplies. This device is also well-suited for consumer electronics such as computers, phones, and tablets. The device is also suitable for applications where fast and reliable protection is required against destructive ESD events and other circuit overvoltage transients. With its ultra-wide operating and clamping range, low leakage current, and high peak pulse current handling capability, the 5.0ST5G Series is an ideal choice for modern applications requiring surge protection.
