The SML4762HE3/5A is a single Zener Diode designed with a reverse breakdown voltage of 5 V. The product is manufactured with both axial and radial lead packages, making it a convenient choice for any design application. It is an ideal choice for controlling surge currents, providing noise protection, and limiting over-voltage transients.

Features

• Reverse breakdown voltage: 5 V
• Small power consumption
• Tight tolerance (± 0.5 V)
• Thermal protection
• Available in axial and radial lead packages

Applications

The SML4762HE3/5A is best for controlling surge currents caused by static electricity, providing noise protection in digital and electronic circuits, and limiting over-voltage transients. It can be used in a variety of applications, such as digital cameras, computer systems, audio equipment, automotive systems, and more.

Working Principle

When it is in the forward bias direction, the current flows freely through the diode, but when it reaches the reverse bias, it is limited. This is where the Zener diode comes into play. It is relatively low in resistance when in the forward bias direction, but when the voltage reaches the breakdown voltage, the current flowing through it drastically increases and provides a sense of regulation. In the reverse bias, the current is limited due to the sudden increase in voltage. The current then decreases until it reaches zero when the forward bias is applied again.

The SML4762HE3/5A is specifically designed to withstand typical reverse biased voltages of 5 V, providing enhanced protection to the circuitry. This allows for efficient and safe source of regulation for electronic systems. It is widely used in commercial, automotive, and industrial applications.
