In fact there a few semiconductor numbering schemes in use. The last stripe as long as there are 3 or less is used to.

As shown in the above figure.

Identifying diodes. There are many types of diodes varying in size from the size of a pinhead used in subminiature circuitry to large 250 ampere diodes used in high power circuits. The same is true for semiconductor devices and manufacturer independent numbering schemes are used for diodes bipolar transistors and fets. Examine the diode carefully and note the color of the casing and the band.

Diodes are electronic components that permit the flow of electric current in one direction only shutting current off when it reverses. How do i identify a diodes value. How to identify simple diodes by shape look for legs on the side.

To identify a glass diode observe its coloration and label and then input its part number into a database. Resistors are electrical components that create resistance in the flow of an electrical current which allows the current to be controlled in order to power a device. 1 two letters and three figures 2 three letters and two figures the first naming method is for general purpose diodes and the second option is for special purpose diodes.

The diode is a two lead device and there is a white or black band at the cathode end. Pro electron numbering scheme this diode bipolar transistor and fet numbering scheme was. These handy devices have dozens of important uses in circuits including as power supplies and radio signal detectors.

Hold the diode with the separate colored stripe to the left. Because there are so many different types of diodes some system of identification is needed to distinguish one diode from another. The band color is usually black though some are white or red.

Polarity identification is simple. Look for both legs under. The european systemes diode code identification consists of an alphanumeric code as per below.

Diodes used for rectification should have sufficient peak inverse voltage piv. Theyre found in nearly all electrical. How to identify resistors.

The peak inverse voltage is the maximum voltage a diode can withstand when it is reverse biased. The stripe identifies the cathode that is the direction the current flows.
