SMBJ5384A/TR13

The SMBJ5384A/TR13 is a single zener diode designed to offer protection from transient voltage spikes in various applications. It is constructed from a silicon material that has been heavily doped, making it highly stable and able to withstand surges of up to 5.5V. This diode has a low rating of 5.5V, making it suitable for regulating low voltages and protecting sensitive components.

This diode’s main application field is for protecting electronic components from damage resulting from voltage spikes. Due to its low zener voltage, the diode can be used as a voltage regulator, such as in a battery charging circuit, preventing the battery from being overcharged. It is also used in circuits to protect from accidental component shorts or disconnections, or from overcurrent from an external power source.

The working principle of the SMBJ5384A/TR13 is based on the zener action of the diode. In normal operation, when the diode is forward biased, a voltage is applied across the diode’s junction, allowing current to flow through the diode. When the voltage becomes too high, the diode goes into reverse breakdown, allowing a limited current to flow. This reverse current is limited by the zener voltage of the diode, and as a result, the voltage is clamped and regulated at the diode’s zener voltage.

The SMBJ5384A/TR13 is a fairly standard single zener diode and can be used in a wide range of applications. With its low zener voltage rating, it is particularly useful for regulating low voltages and providing protection from voltage spikes. From providing protection from accidental shorts or current ripple, to regulating battery charging and providing a low-power voltage clamp, this diode is a versatile and reliable component for any circuit.
