Sigle riportate sui Transistor e Diodi

Le sgile riportate su Transistor e Diodi in genere seguono tre convenzioni: Pro-Electron, JEDEC, or JIS. ; che sono qui di seguito riportate.

Pro-Electron
Form: two letters, [ optional letter], serial number,
Example: BC108A, BAW68, BF239

1^st Letter - specifies the semiconductor material	2^nd Letter - specifies the type of device	Optional 3^rdLetter	Serial number
A Germanium B Silicon C Gallium Arsenide R Compound Materials	A Diode, low power or signal B Diode, variable capacitance C Transistor, audio frequency low power D Transistor, audio frequency power E Diode, tunnel F Transistor, high frequency low power G Miscellaneous devices H Diode, sensitive to magnetism L Transistor, high frequency power N Photocoupler P Light detector Q Light emitter R Switching device, low power e.g. thyristor, diac, unijunction etc S Transistor, low power switching T Switching device power, e.g. thyristor, triac, etc. U Transistor, switching power W Surface acoustic wave device X Diode, multiplier, e.g. varactor Y Diode, rectifying Z Diode, voltage reference	The third letter indicates that the device is intended for industrial or professional rather than commercial applications. It is usually a W,X,Y or Z.	The characters following the first two letters form the serial number for the device type. Those intended for domestic use have a three-figure number (100 – 999), those intended for commercial use normally have one letter and two figures (W10 – Z99)

JEDEC (Joint Electron Device Engineering Council)
Form: digit, letter, serial number, [suffix]
Example: 2N2222A, 2N904

1^st Number designates the type of device	2^{nd Number}	The following figures denote the device serial number	Suffix Optional
1 Diodes 2 Bipolar transistors 3 FET devices 4 OptoCoupler 5 OptoCoupler	N	Serial number of component yields no indication of function or spec. Since this is a serial number may provide insight into date.	A = low gain B = medium gain C = high gain

Japanese Industrial Standard (JIS)
Form: digit, two letters, serial number, [suffix]
Example: 2SA1187, 2SB646

1^st Number designates the type of device	2 Letters	The following figures denote the device serial number	Suffix Optional
1 Diodes 2 Bipolar transistors 3 FET devices	SA: PNP HF transistor SB: PNP AF transistor SC: NPN HF transistor SD: NPN AF transistor SE: Diodes SF: Thyristors SG: Gunn devices SH: UJT SJ: P-channel FET/MOSFET SK: N-channel FET/MOSFET SM: Triac SQ: LED SR: Rectifier SS: Signal diodes ST: Avalanche diodes SV: Varicaps SZ: Zener diodes	Serial number of component yields no indication of function or spec. Since this is a serial number may provide insight into date.	Suffix indicates that the type is approved for use by various Japanese organisations

Manufacturer Specific

Apart from JEDEC, JIS and Pro-electron, manufacturers often introduce their
own types, for commercial reasons (ie to get their name into the code) or to
emphasise that the range belongs to a specialist application.
Common brand specific prefixes are:

MJ: Motorolla power, metal case
MJE: Motorolla power, plastic case
MPS: Motorolla low power, plastic case
MRF: Motorolla HF, VHF and microwave transistor
RCA: RCA
RCS: RCS
TIP: Texas Instruments power transistor (platic case)
TIPL: TI planar power transistor
TIS: TI small signal transistor (plastic case)
ZT: Ferranti
ZTX: Ferranti

Examples- ZTX302, TIP31A, MJE3055, TIS43.
