Super fast rectifiers are commonly used in power supplies, inverters, and other applications where high-speed switching is required. They are also used in applications where low forward voltage drop and low reverse recovery time are important.


1. For surface mounted applications
2. Low profile package
3. Built-in strain relief
4. Easy pick and place
5. Superfast recovery times for high efficiency
6. Plastic package has Underwriters Laboratory
7. Flammability Classification 94V-O
8. Glass passivated junction



1. Super fast rectifiers can switch on and off quickly, making them ideal for high-frequency applications.

2. This diodes have a low forward voltage drop, which reduces power losses and improves efficiency.

3. It have a low reverse recovery time, which reduces the amount of time it takes for the diode to switch from the conducting state to the blocking state.


1. Super fast rectifiers are often more expensive than standard rectifiers.

2. This diode have a lower surge current rating than standard rectifiers, which can make them more susceptible to failure in high-current applications.

3. It is more sensitive to voltage spikes and other transient events, which can cause them to fail prematurely.

The BZX84 series features a small surface-mount package, which makes it ideal for use in compact electronic designs. These diodes have a fast response time and low leakage current, and they are often used in voltage reference applications, as well as in protection circuits to limit voltage spikes and surges.


Q: What is the difference between a Zener diode and a regular diode?

A: While regular diodes are designed to allow current to flow in one direction only, Zener diodes are designed to allow current to flow in both directions when a certain voltage threshold is reached. When the voltage exceeds the threshold, the Zener diode will conduct in reverse bias and regulate the voltage. This property makes Zener diodes ideal for voltage regulation applications.
