1N4619-1

The 1N4619-1 Zener diode is a single diode used to produce a relatively constant voltage in response to changes in current. The working principle of a Zener diode is simple and relies on a reverse bias doped semiconductor that is subjected to a sufficiently high electric field. As the applied voltage across the diode’s terminals increases, and the electric field becomes too strong, the diode will conduct in the reverse direction and pull the voltage down to a specific level, known as the Zener voltage.

The 1N4619-1 Zener diode has a voltage breakdown range of 5.1V to 5.6V, with a maximum power dissipation rating of 1 Watt. It is encapsulated in a DIP package, enabling it to be easily used in a wide variety of applications. Its typical reverse current is 1mA and its maximum reverse voltage is 7V.

The 1N4619-1 Zener diode has several common applications. One of the most common applications for it is to suppress transients, which can be caused by lightning, power surges or induced by other high-powered devices on the same line. It can also be used to regulate voltage; when a voltage source produces too much voltage, the Zener diode will act as a ‘clamp’, limiting the input voltage to the specific Zener voltage. Other applications include clamping, bypassing and reverse voltage protection in telecommunication and computer equipment. In these applications, the 1N4619-1 Zener diode is usually ‘wired in’ between a power source and any sensitive parts of the circuit. It effectively absorbs any excess voltage and makes sure that the delicate parts are not damaged.

The 1N4619-1 Zener diode is capable of withstanding a wide range of temperature extremes, making it suitable for both industrial and consumer applications in environments that are exposed to temperatures in excess of 150°C. It is also available in a variety of packages including DO-35, SOT-23 and SMA, making it suitable for a variety of board designs.

In summary, the 1N4619-1 Zener diode is a single diode used to create a relatively constant voltage in response to current changes. It has a Zener voltage range of 5.1V to 5.6V and a power dissipation rating of 1 Watt. It is commonly used for transient suppression, voltage regulation and reverse voltage protection in telecommunications and computer equipment.
