SMZJ3788BHE3/5B

A SMZJ3788BHE3/5B diode is one of the most popular types of single Zener diodes. It offers an excellent combination of low forward voltage drop and high power dissipation of 3.0 watts. It has a high reverse breakdown voltage range of 3.3 volts to 5.0 volts, making it suitable for a wide range of applications. Furthermore, it features a low leakage current of less than 20 microamps and low capacitance of 200 picofarads.

The SMZJ3788BHE3/5B diode is primarily used for voltage regulation applications and in high-voltage circuits. It is often used in power supplies, logic circuits, surge protectors, and motor control circuits. Its maximum rated junction temperature of 175°C makes it suitable for high-temperature applications such as automotive and medical electronics.

When biased in reverse, the SMZJ3788BHE3/5B diode exhibits a Zener breakdown voltage of 5.0 volts. This ensures that the reverse current does not exceed the Zener breakdown voltage, thereby maintaining a stable output voltage. As the voltage across the diode increases, the diode current conduction increases logarithmically.

When biased in a forward direction, the diode exhibits a very low forward voltage drop of 0.6 volts. This ensures low power losses and the ability to handle larger amounts of power. The low forward voltage drop also helps extend the service life of the diode.

The SMZJ3788BHE3/5B diode also features a short-circuit current that is limited to a maximum of 0.15 amps, helping to reduce the risk of circuit damage. The diode has a maximum cut-off frequency of 1 MHz and a maximum recovery time of 500 nanoseconds. This makes it suitable for applications where high switching speeds and low noise levels are required.

Overall, the SMZJ3788BHE3/5B diode is an excellent choice for a wide range of applications, including power supplies, logic circuits, motor controls, and surge protection. Its low forward voltage drop, high power dissipation, and low leakage current make it well suited for high-temperature applications, such as automotive and medical electronics.
