☑ Diode Terminal Identification

Pin identification of few available diodes. With brown being a 1 orange a 3 and white 9 the device would be identified as a type 139 semiconductor diode or specifically 1n139.

What Is A Diode Basics Types Symbols Characteristics

Identify the anodecathode of leds while referring to any schematic involving leds we sometimes get confused with the identification of the terminals.

Diode terminal identification. The led pins can be identified by inspecting the led from the top view. The anode terminal is the metallic contact on the screw part of the triac. Take for example a diode with brown orange and white bands at one terminal and figure out its identification number.

So for identification leds comes with a unique way to identify its terminals as anode or cathode. In the case of a p n junction diode the anode is the p type and the cathode is the n type. The one with a flattened edge is the negative pin and the straight pin is the positive pin.

Led light emitting diode. It is the simplest of semiconductor devices. The anode which is the positive terminal and the cathode which is the negative terminal.

Sometime the diode symbol creates confusion tooidentifing a leds the cathode and anode of a led is very easy by looking inside. Ujt unijunction. A diode is so called because it has two terminals.
