Zener diodes. Zener diodes are semiconductor diodes which have been manufactured to have their reverse breakdown occur at a specific, well-defined voltage (its “Zener voltage”), and that are designed such that they can be operated continuously in that breakdown mode. @ IF = 10 mA for all types) Device Device Marking Zener Voltage (Note 1) Zener Impedance Leakage Current VZ (mV/k) @ IZT C @ VR = 0 VZ (Volts) @ IZT f = 1 MHz ZZT @ IZT ZZK @ IZK IR @ VR Min MaxmA A Volts pF NZD2V4MUT5G D*** 2.28 2.52 5 100 1000 … Available. MM3Z Zener Diode. DIODE ZENER 1N5337BRL CASE 17 disponible au meilleur prix sur Conrad.fr ! With 2 V across a 400 ohm resistor, the current through that resistor (and the diode, in series) is 5 mA. The fixed voltage property of Zener diodes makes them extremely handy as quick voltage references. Zener ESD Protection Diode Dual Common Anode Zeners for ESD Protection These dual monolithic silicon zener diodes are designed for applications requiring transient overvoltage protection capability. Diode Zener Single 13V 500mW Automotive 2-Pin SOD-123 T/R . http://onsemi.com 3 ZENER DIODE THEORY INTRODUCTION The zener diode is a semiconductor device unique in its mode of operation and completely unreplaceable by any The current supplied by R15 is dependent on the input voltage. Zener Voltage Regulator IF V I IR IZT VZ VR VF 1SMA59xxBT3G Series, SZ1SMA59xxBT3G Series www.onsemi.com 2 ELECTRICAL CHARACTERISTICS (TA = 25°C unless otherwise noted, VF = 1.2 V Max. In the circuit above, there is 10 V across the Zener diode, and 2 V across the resistor. 50 µA for the zener diode, totaling 1.25 mA for this circuit.
They are intended for use in voltage and ESD sensitive equipment such as computers, printers, business machines, communication systems, medical equipment and other applications. Zener voltage references. A zener of around 7-8V can be selected to work with a diode to cancel the temperature drift. For first step a Zener diode with 2v voltage is ok, but as i said when i used the model i posted before, with different source resistors, the gate voltage which is connected to the diode, changes. ON Semiconductor products offer the best available combination of superior quality, features, and packaging options. surge protection diodes have high impedance below and low impedance above their breakdown voltage. Ce site Web utilise des cookies . The zener diode is a unique semiconductor device, and it fulfils many different needs unlike any other component. We keep stock wide range of Zener Diodes kits of sizes : SOT23, SOD80, SOD123, SOD323. The diode is connected to the supply voltage by a resistor. ON SEMICONDUCTOR MM3Z8V2T1G | Diode: Zener; 0.3W; 8.2V; SMD; reel,tape; SOD323; single diode - This product is available in Transfer Multisort Elektronik. I dont know it was because of a wrong Zener model or the circuit itself? Vishay / Small Signal & Opto Products (SSP) Diode,Zener,Vr 15V,If 200mA,Pkg DO-41,Vf 1.2V,Tj +175C,Cs 304mA,Pd 1.3W,Ir 17mA

A lower power solution based on the NCS2220 comparator is discussed in a later section. Whether you are working on a cutting edge design, upgrading an existing design or purchasing for your BOM, ON Semiconductor is your preferred, reliable source of industry standard Zener diodes. www.onsemi.com 3 Surge Protection Diode Protection Circuit Surge protection diodes provide protection to a transceiver by clamping a surge voltage to a safe level. They are used as discrete components, and also within ICs that require a reference voltage. Zener Diodes 5W Surmetic, 1N5347 to 1N5363 Series, ON Semiconductor. Manufacturer description. NZD5V1MU Series www.onsemi.com 3 ELECTRICAL CHARACTERISTICS (TA = 25°C unless otherwise noted, VF = 1.1 V Max.

Part Name Description ; 1N2804A : 500mW, 95mA, Silicon Zener Diode (AA Enabled) 1N2810A : 50W, 3.6A, Silicon Zener Diode (AA Enabled) ON Semiconductor. inquire article now . MM3Z Zener Diode. Zener diodes (also sometimes called voltage reference diodes) act like a normal silicon diode in the forward direction, but are designed to break down at a specific voltage when subjected to a reverse voltage. Minimum order quantity: 21.000. By the nature of the application, As the ac input voltage is reduced, the available bias current will reduce. possible alternatives. Manufacturer ONSEMI.

Datasheets. This complete new line of 3 Watt Zener diodes offers the following Delivery time on request . Manufacturer. Needless to say, the diode and zener junctions need to be in intimate thermal contact, or temperature cancellation will not be a success.
