JAN1N4622DUR-1

The JAN1N4622DUR-1 is a single Zener diode packaged in a DO-204AL package. It is a general-purpose Zener diode, with a typical Zener voltage of 4.7 V and a maximum Zener impedance of 20 Ω. This Zener diode features a high reverse power, from 0.5 W up to 1 W, and a low refulse current. It has excellent clamping capability, as well as a wide range of operating temperature, from -55°C to 150°C.

Applications

The JAN1N4622DUR-1 reaches its maximum power rating of 1W at the Zener voltage of 4.7 V. This makes it suitable for use in a wide range of applications, such as power regulation, voltage stabilization, and voltage limiters in mobile and portable electronic devices, motor and industrial control systems, and automotive electronics.

Working Principle

The JAN1N4622DUR-1 is a Zener diode, a special type of diode that conduct current when a voltage is applied in the reverse direction. This voltage is the Zener voltage, the unique characteristic of Zener diodes. The Zener diode allows current to flow in the reverse direction when the voltage reaches the Zener voltage, which will be maintained as the voltage across the diode. This type of operation is called Zener breakdown, and it allows the diode to regulate the output of the power supply. Unlike a standard diode, which blocks the current, the JAN1N4622DUR-1 Zener diode will allow the current to flow with constant voltage. This makes it suitable for voltage regulation applications, such as regulating the output of a power supply.

Conclusion

The JAN1N4622DUR-1 is a single Zener diode packaged in a DO-204AL package. It has a typical Zener voltage of 4.7 V and a maximum Zener impedance of 20 Ω, which makes it suitable for use in a wide range of applications, such as voltage regulation, voltage stabilization, and voltage limiters. It has a high reverse power, from 0.5 W up to 1 W, and a low refulse current, which gives it excellent clamping capability and a wide range of operating temperature. It has a unique working principle, where the voltage reaches the Zener voltage and the current is allowed to flow in the reverse direction, allowing for a constant output voltage.
