     Surface mount devices (SMDs) are used in a growing number of commercial and industrial products. SMDs
have improved performance over through-hole components due to their smaller size, shorter internal leads, and
smaller board layouts. These factors reduce the circuit's parasitic inductance and capacitance. SMDs can also be
more cost effective than traditional through-hole components due to the smaller board size, fewer board layers,
and fewer holes. Today more than 50% of active semiconductor components are surface-mounted.
     At the same time, SMD devices are, by their very nature, too small to carry conventional semiconductor type
numbers. Therefore, a somewhat arbitrary coding system has grown up, where the device package carries a simple
one, two or more character or graphic ID code. Thus it is necessary to take into account that the colour and (or)
placing of alphanumeric or graphic symbols are also important.
     Identifying the manufacturers type number of an SMD device from the package code can be a difficult task.
Unfortunately, each device code is not necessarily unique.
     It is possible for various manufacturers to place different devices in the same case with the same SMD-code.
For example, with a 6H SMD-code in a SOT-23 case might be either a npn-transistor BC818 (CDIL) or a capacitance-
diode FMMV2104 (Zetex) or a n-channel JFET transistor MMBF5486 (Motorla) or a pnp-digital transistor MUN2131
(Motorola) or a pnp-digital transistor UN2117 (Matsushita) or a CMOS-integrated circuit- voltage detector with reset
output R3131N36EA (Ricoh). Even the same manufacturer may use the same code for different devices.
     To identify a particular SMD device, is necessary to identify the manufacturer, package style and note the ID
code printed on the device.
     The identification of the manufacturer is possible only if on the case are printed the manufacturer's logos, but it
not always happens. Besides, sometimes it is possible to determine the manufacturer with indirect tags. Many recent
Motorola devices have a small superscript letter after the device code, such as SAC (this smaller letter is merely a
month of manufacture code). Siemens and Infineon devices usually have a lower case 's' (ATs, LOs). Philips
devices usually have a lower case 'p' (AHp, Z1p, pB0) or '-' (D-Q, Z-S) for the devices made in Hong Kong and 't'
(ZtS, tT9, Y7t) for the devices made in Malaysia. In section 5 are submitted the logos of the SMD devices manufac-
     The package style is another problem for the identification of SMD devices. The different manufacturers can
designate identical cases according to the various standards (or according to the internal firm system). Besides the
various cases can have an identical kind (form) and differ only by sizes, but this distinction of sizes so it is not
enough, that can be is measured only by special measuring devices. The conformity of the cases name of different
manufacturers is submitted in the bottom table:
