TVS (Transient Voltage Suppression) diodes are semiconductor components designed for protection against electrostatic discharge (ESD) and voltage spikes caused by cross-talk, lightning or switching inductive loads. TVS diodes are widely used in many applications, including automotive, industrial, medical, and consumer electronics. The USB50803C-A/TR7 is a TVS diode device designed to protect sensitive circuits against overvoltage transients.

The USB50803C-A/TR7 is part of the UniVolt® series of Uni-Directional (Uni-Dir) transient voltage suppressors. It is designed to protect sensitive electrical components from damage due to overvoltage transients. The device offers reliable protection from transient voltage spikes, and it is capable of withstanding multiple sequential spikes without showing any degradation. The USB50803C-A/TR7 is designed with an integrated vertical eleventh generation (V11) ESD device which allows for significantly better ESD performance than competitive solutions. It is designed to meet or exceed the ESD requirements of IEC61000-4-2 level 4 ( 8 kV contact, 15 kV air). This device offers superior protection for automotive, home appliance, or portable applications against overvoltage transients.

The USB50803C-A/TR7 has a breakdown voltage of 13.5 V and a peak pulse power of 1.5 KW. It can operate up to 82°C with excellent stability and efficiency. The maximum peak surge current rating of this device is 1.5 A. The device is available in a TR7 package outline with standard lead (Pb)-free solder joints. The package features superior thermal resistance, making it an ideal solution for applications that require higher power dissipation.

The USB50803C-A/TR7 is designed to protect a circuit from destructive overvoltage transients by clamping them to a safe voltage level. The device works by using a Zener diode connected to a transistor with a series limiting resistor. The Zener diode acts as a voltage reference and the transistor is used to dissipate the energy of the transient current. When a transient voltage spike occurs, the Zener diode effectively clamps the spike to a lower voltage level, while the transistor is switched on by the spike current to safely dissipate the rest of the energy. The USB50803C-A/TR7 is designed to provide superior ESD protection, while also allowing for normal switching and high-speed operations in sensitive circuits.

The USB50803C-A/TR7 offers a wide range of features which make it suitable for a variety of applications. It offers excellent ESD protection, high voltage transients suppression, superior thermal resistance, and low-current operation. The device is designed with fast turn-off time which makes it suitable for high-frequency applications. The USB50803C-A/TR7 also offers improved system reliability due to its wide operating temperature range (- 65°C to 145°C).

The USB50803C-A/TR7 is an ideal solution for a variety of applications, such as automotive, industrial, medical, and consumer electronics. This device is designed to offer superior protection from electrostatic discharge (ESD) and overvoltage transients. It is capable of withstanding multiple sequential spikes without showing any degradation. The device is designed with an integrated vertical eleventh generation (V11) ESD device which allows for improved ESD performance.
