SMDB05E3/TR7 Circuit Protection

The SMDB05E3/TR7 is a bi-directional transient voltage suppressor (TVS) diode that belongs to the TSMB series of unidirectional and bidirectional suppressor diodes. It is designed to protect sensitive electrical and electronic equipment from voltage spikes. The TVS diode serves as a voltage-activated switch that is triggered by high-voltage spikes or electromagnetic interference (EMI). When the voltage exceeds predefined levels, the diode quickly conducts current away from vulnerable components to ground. The diode is self-releasing when the voltage falls to a safe level.The SMDB05E3/TR7 is a unidirectional TVS diode designed for ESD protection on automotive applications. It is available in a bidirectional configuration for ESD and surge protection. The diode is capable of supporting a peak power dissipation of 500 watts. It is constructed out of a glass passivated junction. The device has a peak pulse power rating of 8000 watts and a peak working voltage of 5.0 volts.

The SMDB05E3/TR7 is designed to protect sensitive automotive circuits from transients. It can be used in switches, ignition systems, engine control modules, and sensors. The TVS diode has a low clamping voltage and a low operating capacitance. This allows it to provide effective protection against high energy spikes. The diode is also temperature-compensated, allowing it to remain stable over a wide temperature range. The diode has a wide-operating temperature range of -55°C to +150°C, making it suitable for automotive applications.

The TVS diode is driven by its working principle. When a voltage above the diode\'s peak working voltage is applied to the diode, it quickly turns on and conducts current away from sensitive components to ground. The diode will then turn off once the voltage falls below the peak working voltage. This allows the TVS diode to provide reliable ESD and surge protection for the connected circuit without interfering with normal circuit operation. The TVS diode is effective in reducing the peak voltage and rate of rise of transient voltages.

In conclusion, the SMDB05E3/TR7 is a bidirectional TVS diode designed for ESD and surge protection. It is capable of providing effective voltage-clamping and current-dissipation protection against high-energy ESD and transient events. The diode exhibits a low operating capacitance and clamping voltage. It also has a wide-operating temperature range, making it suitable for automotive applications. The diode is driven by its working principle, which allows it to protect sensitive electrical and electronic equipment from voltage spikes.
