TVS-Diodes play an important role in the protection against power surges that goes into and out of electronic devices. The SMDB05CE3/TR7 is a unidirectional TVS-Diode that is very popular, and is a suitable choice for the protection of data line surge applications. It is designed to provide protection for 30 Vdc lines from air discharge waveforms 8/20 μs pulses.The SMDB05CE3/TR7 has a working voltage range of 10 - 50 Vdc, and its power dissipation is range from 0.5 to 17.5 W. It has a breakdown voltage at 28 Vdc with a maximum peak pulse power dissipation of 3000 W (8/20 μs). This makes it suitable for a variety of applications as it can be used for both simple and complex data protection.The SMDB05CE3/TR7 can be used in high-speed signal lines for data transmission in industrial electronics, consumer electronics, automotive electronics and computers. It is often used as a Transient Voltage Surge Suppressor (TVSS) to protect the device from electrical surges. It is typically used when there is a need to protect sensitive components from the negative effects of an electrostatic discharge (ESD). The SMDB05CE3/TR7 is also suitable for higher-power applications such as high-voltage systems, and as a surge protection device for outdoor phone lines.The TVS-Diode works using the principle of a reverse biased diode. It acts in a similar way to a normal diode but instead of allowing current to flow in one direction, the TVS-Diode has a voltage-controlled switch that is activated by a sudden rise in voltage. When the voltage rises quickly, it creates an avalanche breakdown within the device. This triggers the TVS-Diode to switch off and conduct the surge to the ground. The SMDB05CE3/TR7 provides a maximum clamping voltage of 46.5 V for 8/20 μs pulses, which makes it a reliable protection against common power surges.The main advantage of the SMDB05CE3/TR7 is its high power capability, which makes it suitable for a wide range of applications. It is an efficient protection device as it clamps the voltage to a safe level in a very short amount of time. This makes it especially suitable for equipment that is exposed to a variety of voltage surges.The SMDB05CE3/TR7 TVS-Diode can help protect your equipment against harmful voltage spikes. By preventing the voltage from rising too quickly and exceeding the breakdown voltage, it helps protect electrical circuits from damage caused by transient voltage threats. This makes it an effective safeguard against power surges.
