What type of diode is the 1N4148?

What type of diode is the 1N4148?

silicon switching signal diode
The 1N4148 is a standard silicon switching signal diode. It is one of the most popular and long-lived switching diodes because of its dependable specifications and low cost. Its name follows the JEDEC nomenclature.

How do you measure voltage across a diode?

A diode is best tested by measuring the voltage drop across the diode when it is forward-biased. A forward-biased diode acts as a closed switch, permitting current to flow. A multimeter’s Diode Test mode produces a small voltage between test leads.

How do you read a diode color code?

The first and second stripes are single digits; the third is the number of zeroes that follow the first two numbers. Match the numbers with the colors: black is 0, brown is 1, red is 2, orange is 3, yellow is 4, green is 5, blue is 6, violet is 7, gray is 8, and white is 9.

What is a 1N4148 diode?

1N4148 Diode is a fast switching diode. It is fabricated in planar technology, and encapsulated in hermetically sealed leaded glass SOD27 (DO-35) packages.

How to identify the cathode terminal of in4148 diode?

The cathode terminal can be identified by using a grey bar as shown in the picture above. For IN4148 Diode, the maximum current carrying capacity is 300mA, it can withstand peaks up to 2A. The speciality of this diode is its fast recovery time of 8ns at a forward current of 10mA, hence this diode is used in places where fast switching are involved.

What is the maximum current carrying capacity of in4148 diode?

For IN4148 Diode, the maximum current carrying capacity is 300mA, it can withstand peaks up to 2A. The speciality of this diode is its fast recovery time of 8ns at a forward current of 10mA, hence this diode is used in places where fast switching are involved.

What is the difference between in4007 and in1n4148?

1N4148 is a commonly used switching diode (normal forward current If: 150mA, maximum repetitive peak voltage Umax: 100V, reverse recovery time trr: 4ns). IN4007 is also a common rectifier diode (positive power constant forward current If:1A, maximum repetitive peak voltage Umax:1000V).
