1N4148_T26R

Introduction

The 1N4148_T26R diode is a small signal switching diode with a silicon junction. It can also be known as a high-speed switching diode, and it is used in a variety of applications due to its low forward voltage drop, high reverse voltage, and low reverse current leakage. 1N4148_T26R is part of Diodes, Rectifiers family and Single category.

Application Field

1N4148_T26R is used in a variety of switching applications, including in consumer electronics, such as television and radio sets, amplifiers, and switched-mode power supplies. It can also be used in automotive applications, such as turn-on delay circuits and reverse polarity protection circuits. 1N4148_T26R is also used in instrumentation and power supplies, as well as voltage regulation circuits.

Working Principle

The 1N4148_T26R diodes typically operate at a forward voltage drop of 1.1 V and a reverse voltage rating of up to 75 V. The forward- and reverse-current ratings are typically 200 mA and 8 µA for the 1N4148_T26R diode and are increased dependent on the current handling capacity of each component. When forward biased, the diode is essentially a closed switch that conducts current in the forward direction. When reverse biased, the diode is essentially an open switch and, as a result, does not permit the current to flow in reverse. The average forward current can be determined from the temperature and voltage by using the forward voltage-current relation for the diode. The switching physics of the 1N4148_T26R diode is related to the voltage-dependent depletion-layer capacitance in the junction. As the voltage increases, the depletion-layer width reduces, giving rise to a decrease in the junction capacitance. This decrease in capacitance determines the switching properties of the diode.
