DL4746A-TP

Diodes - Zener - Single: DL4746A-TP Application Field and Working Principle

The DL4746A-TP is a single Zener diode product of a series of Zener diodes from Diodes Incorporated. It is a 4.7V, 360mW device that features a small form factor and thermoplastic compound case. Specifically, the DL4746A-TP measures just 0.5mm x 1.6mm in size, making it ideal for applications where physical space is limited, such as in hand-held and portable electronics.

The DL4746A-TP is a special type of Zener diode which makes use of the Zener breakdown effect. This effect occurs when a diode is operated in a reverse-biased state and a certain voltage is reached, causing the diode to enter a breakdown mode. During a Zener breakdown, electrons are able to tunnel through the device and excessive current can flow. This phenomenon is useful in applications such as voltage regulation, where a precise output voltage can be maintained.

The DL4746A-TP is particularly appealing due to its wide operating temperature range of -40℃ to +100℃, making it suitable for a variety of conditions. It also offers low leakage current thanks its low Zener impedance of 0.9V which helps to maintain a stable output voltage. Finally, the device is manufactured in compliance with RoHS and lead free requirements, making it an environmentally-friendly option.

In summary, the DL4746A-TP is a 4.7V, 360mW Zener diode from Diodes Incorporated which features a small, thermoplastic compound case and low Zener impedance. It is ideal for applications where physical space is limited, and is also suitable for a wide range of temperatures and lead free environments. Its successful manufacturing technology makes it a reliable, cost-effective solution for many circuit designs.
