Two-terminal semiconductor that conducts current in both directions Zener diodes have the peculiarity of having a sharp reverse breakdown voltage (known as zener voltage) that allows the device to conduct current in both directions without suffering damages. Function : 12V, 500mW, Zener Diode. ZENER DIODE datasheet, ZENER DIODE pdf, ZENER DIODE data sheet, datasheet, … The 1N4148, PH4148 and 1N4448 are high-speed switching diodes fabricated in planar technology, … I'm looking at this diode and see that it's zener voltage is 3.3V, but it's max forward voltage is 0.9V. There is a difference between a diode and a Zener diode. Fig. 4. How to select a Zener Diode: A Zener diode is another form of diode, but is used for entirely different purpose.

Weight: 0.35 grams (approximate) Created Date: 12/16/2015 3:25:13 PM Description : “C27” – means 27 Volts, its the last part of the full type (e.g. 1N4728A Equivalent Zener Diodes: 4.7V Zener, 5.1V Zener, 6.8V Zener, 7.5V Zener, 15V Zener . ... Zener Diodes Diode Zener 3.0V 200mW 5% Enlarge Mfr. Simple Zener-based circuit (Model drawn in LTspice, Source: Elizabeth Simon) The associated simulation below shows how the Zener follows the supply voltage as it ramps up … Because of this unique characteristic, they can be placed in parallel across a load and used as a voltage regulator. The above one is a picture of the diode characteristics table. Zener Diode is a general purpose diode, which behaves like a normal diode when forward biased. Note: Complete Technical Details can be found at the 1N4728A datasheet given at the end of this page. 1N4728A Equivalent Zener Diodes: 4.7V Zener, 5.1V Zener, 6.8V Zener, 7.5V Zener, 15V Zener . The 500mW, BZX55 series zener diodes are generally available in the range varying from 2.4 Volts to nearly about 100 Volts. Bulk Packs and Special Quantitiy Pricing Available. 3) Compatible with chip mounter for automated produc-tion. The part requires a small quiescent current for regulation, and regulates the output voltage by shunting more or less current to ground, depending on input voltage and load. But when it is reverse biased above a certain voltage known as zener breakdown voltage or zener voltage or avalanche point or zener knee voltage the voltage remains constant for a wide range of current.. Clarence Zener is the scientist who discovered this electrical property and the device is … Due to this, more current flows through a zener diode as compared to a normal junction diode. A Zener diode is a special type of diode designed to reliably allow current to flow "backwards" when a certain set reverse voltage, known as the Zener voltage, is reached.. Zener diodes are manufactured with a great variety of Zener voltages and some are even variable. However, its datasheet on page 4 states that it has a Reverse Leakage current of Package : DO-41 ( DO-204AL ) Type . Products include the 500 mW PLZ series, which features a MicroMELF package with an SOD-323 0.6 mm package height and very narrow Zener voltage … the diodes anode connects to the negative supply.
