The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.

What is a temperature sensor diode? It is a general silicon diode. I will show how it works. When a diode is forward biased, the resistance of a diode changes with temperature. Usually, we have seen this type of equipment, a thermistor. It is a type of resistor and easy to use. But we do not see it in normal use. In fact, we can use all semiconductor devices as a temperature sensor. GET UPDATE VIA EMAIL Temperature sensor diode 1N4148 Inside semiconductors have resistances. Its resistances will reduce when it to be hot. In the opposite way, when it is cold its resistance rises. We can use many semiconductors, transistor, IC, SCR, and more. But this circuit uses the diodes, D1-1N4148. Because it is easy to use, cheap, see all-time in store. How it works In fact, when the diode is in forward biased. It has voltage across about 400mV to 500mV at current about 1mA. This voltage level depends on the current and the substance used to generate these diodes. In silicon diode, the voltage across it will reduce about 2mV in each one degree Celsius temperature. We so can use it. Also, you can use a transistor, diode bridge and more. They are also silicon semiconductors. In the circuit above is a simple temperature sensor diode, D1. First, get a steady voltage power supply. The Dual +15V/-15V DC Regulator is suitable for here. Second, a constant current comes to D1 through R1. When the temperature of D1 changes, the voltage across it changes, too. But this changing makes voltage chang...

1N4148 diode is a standard signal P-N junction diode. It has a medium voltage drop of 0.72 V and a low current rating of 300mA. Hence, the 1N4148 is mainly used for general operations like fast switching, high-speed rectification, and protection of telecommunication devices. In this post, we will discuss the applications and pinout of the 1N4148 diode. We will also see the equivalents of this diode, which you can use, as its substitute. • • • • • • • • • • Here’s what 1N4148 is used for The 1N4148 is your go-to diode when it comes to normal use. You can use it in Digital logic circuits, in power supplies due to its fast switching capability and quick recovery time. It is sometimes used in rectifier circuits where operating voltages are less than 100 V. Although Is 1N4148 a Zener diode? No, 1N4148 is not a So, what is a 1N4148 Diode? 1N4148 is a type of switching diode. These diodes provide quick switching (up to about 100 MHz) and are popularly used in low-current applications. 1N4148 switching diode was first registered at JEDEC in 1968 for military and industrial applications. Due to its small size, low cost, and easy availability, it is now the most commonly produced switching diode, replacing the former 1N914 diode. Features of 1N4148 diode • The maximum current carrying capacity is 300mA. • Its recovery time is 8ns. • The power dissipation for this device ranges from 80mW to 1kW. Modes of Operation The diode works similar to a signal diode allowing current flow in a s...
