Diodes are electronic components used to control the flow of electrical current between two separated points in a circuit. They act like tiny controllable valves, allowing current to flow in one direction only. Diodes also serve as basic switches, controlling an electrical signal’s flow in either direction, depending on the voltage at the diode. Zener diodes are a special type of diode used for voltage regulation, allowing current to flow in one direction, and stabilizing the voltage over a certain range. The SMBJ4731CE3/TR13 is a single zener diode for use in a variety of applications.

The SMBJ4731CE3/TR13 is a 3.3 V zener diode with a power dissipation of 200 mW, cathode wire bondable, and is designed to handle an energy of 500mW with a reverse breakdown voltage of 6.2 to 7.8 V. It is also equipped with a surge current rating of 5 A, and an average forward current of 1A. This diode is made of silicon, is RoHS compliant with lead-free solder plating, and is rated for an ambient temperature range of -55°C to 125°C.

The SMBJ4731CE3/TR13 possesses a wide range of possible applications due to its range of features. It is ideal for voltage regulation and voltage clamping in circuitry, as it stabilizes the voltage from 6.2 to 7.8V. It can also be used for reverse current protection and as a backup for other components, since it will only allow current to pass in one direction. When used in this regard, the diode must be forward-biased, meaning that current can only flow through it if above its turn-on voltage. Lastly, the SMBJ4731CE3/TR13 can also be used as a voltage stabilizer in circuits where over-voltage or short-circuit protection is needed.

The basic working principle of the SMBJ4731CE3/TR13 is relatively simple. When the voltage at the diode drops to a certain level, it will transition from its high resistance state, or “off” state, to its low resistance state, or “on” state. When in the “on” state, the diode will pass current in one direction and restrict current from flowing in the opposite direction. The “on” state of the SMBJ4731CE3/TR13 is achieved when the voltage between the anode and cathode is above 6.2V. When the voltage between the anode and cathode is below 6.2V, the diode will be in an “off” state, and no current will be passed through. After a certain voltage, the SMBJ4731CE3/TR13 will enter a “zener breakdown” state and current will no longer pass through the diode. The breakdown voltage of the diode is 7.8V, meaning that when the voltage at the diode reaches 7.8V, current will cease to flow.

The SMBJ4731CE3/TR13 is a single zener diode for use in a variety of applications. Its features make it suitable for voltage regulation and voltage clamps, as well as reverse current protection and voltage stabilization. Its simple working principle involves transitioning from an “off” to an “on” state above 6.2V, and reaching its breakdown voltage of 7.8V and ceasing its current flow. Overall, the SMBJ4731CE3/TR13 is a reliable and durable diode for use in a variety of applications.
