How to Identify Component Symbols on Schematic Diagram
Identifying with Symbols on Schematic Diagram is very easy task, it's just like reading ABC's on English alphabet. Since we are talking about mobile phone's circuit here, we are going to tackle only on its symbols being used herein, unlike in some major electronics components which have a lot of c om omponent ponent symbols. symbols. Mostly, because Cellphone circuits have a lot of Integrated Circuit ( IC ) meaning meaning the circuits is being compact into a smaller circuit to produce, and save a very small space to put a huge circuit connection into one tiny piece of circuits. I have inserted the Layout of each component and how it's look's like mounted on a PCB ( Printed Circuit Board ) for better and easiest way of understanding. Simply Click on Components Category for more Detailed Infos.

I what phone is zener diode ? There are varistors , but i never se en a zener in a phone . Varistors are like a resistor . And theyr role are to protec t ic's from hight c urent . Usualy are used in interfaces like keypad .

The Following User Says Thank You to =GsM_Angel= For This Useful Post:
Varistors are being pack into c hips like what you said used to protec t high current. Y our are pertaining to EMI-ESD filters c hips the so c alled Crystal IC by many tec hnicians. There are bunch of v aristors inside it. Varistors symbol is a two diode connected in both anodes and both cathodes connected to which the current flow. Zener is always been in a c ircuit and always play the roll to rec tify and st abilized voltage and c urrents. Newly designed Zeners are SMD (Surfac e Mounted) so it is not easy to identify them by looks. If you are familiar with Integrated Circuit Datasheets ( chips schematic diagrams) you can see that it is accompanied zeners inside it.
