TVS - Diodes are an integral part of any electrical circuitry, providing an essential level of protection for both the components and the circuits themselves against overvoltages and electrical disturbances. The USB50803/TR13 is a popular choice among engineers for its high performance in demanding applications, such as those in the automotive, industrial and medical markets. It is a key device for protection against transient voltage surges, which are often the result of sudden conduction of current in a circuit, an improper shutdown, or the sudden failure of some other component, such as a relay solenoid.

The USB50803/TR13 is a uni-directional, low capacitance, avalanche-mode diode designed to protect against electrical overstress. In this instance, the protection is provided by the combination of two components. The diode, typically a 6.8V zener diode, is connected in series with a TVS diode array. The combination provides robust protection against voltage transients up to +1000 V, for a variety of applications, including signal line protection.

The USB50803/TR13 offers superior EMI/RFI noise filtering, with an ultra-low capacitance of 0.19pF, and a low clamping voltage of 10.3V, making it suitable for use in high-frequency communication systems. This device is rated for operating temperatures between -55 to +175°C, making it ideal for use in industrial, automotive and medical equipment. It is also Lead (Pb) free and RoH/UL recognized.

When exposed to transient overvoltages, the diodeclamp array of the USB50803/TR13 absorbs the energy, reducing the peak voltage to a safer level and protecting the circuit from any damage. The TVS diode array is arranged in series, so that when there is an impulse or surge of current, it is distributed across the components in the series. The effect of the surge is thus reduced, as the energy is dissipated in the form of heat. Additionally, the components of the array are designed to have a high surge-current rating, allowing them to handle large electrical shocks, without themselves being damaged.

The USB50803/TR13 provides around 3A of clamping current per IEC 61000-4-6, and 10A peak pulse current per MIL-STD-883. In addition to its surge protection capabilities, it offers unmatched ESD protection with up to 30 kV Contact and Air Discharge according to the IEC 61000-4-2 standard. It also offers excellent suppression of electromagnetic interference, making it an ideal choice for applications where EMI/RFI filtering is essential, such as in professional audio and video equipment.

The USB50803/TR13 is a highly reliable device suitable for a variety of applications and scenarios, offering superior protection against overvoltage transients, ESD protection and low noise interference. Its ultra-low capacitance and low voltage clamping, combined with its ability to withstand high surge currents, makes it the ideal choice for demanding, complex applications.
