Model of complete parts of an apparatus, it is to include principal part commonly model, prepositive, suffixal wait for composition. General engineer cares prefix and main body model only, and meeting oversight is suffixal, connect prepositive metropolis oversight to a few engineer very. Of course, not be all parts of an apparatus have certainly prefix and suffixal, but, want this parts of an apparatus to have only prefix and suffixal, not negligible.

 

Prefix of parts of an apparatus is the series with delegate older parts of an apparatus commonly, for instance the 74LS series in logistic IC represents low power comsumption IC of logic of Xiao Te radical, 74ASL series representing’s advanced low power comsumption IC of logic of Xiao Te radical, 74ASL set is better than the function of 74LS series.

 

For instance, 2N5551 dynatron and MMBT5551 dynatron are both enclose different, one is plug-in unit (TO-92) , one is to stick piece (SOT-23) . If 5551 dynatron are written only on BOM, that affirmation does not know is which.

 

The phenomenon of oversight prefix is common a bit a bit less, but the circumstance with suffixal oversight is more. Generally speaking, suffixal have the following these good:

 

1, divisional detail function

 

For instance, for the restoration chip MAX706 that takes MAXIM company, it is likewise 706, but have voltage of a few kinds of threshold values, for instance the threshold values voltage of MAX706S is 2.93V, the threshold values voltage of MAX706T is 3.08V, the suffixal “S” here and “T” represent different threshold values voltage.

 

2, grade of divisional parts of an apparatus and working temperature

 

For instance the TL431 of fiducial voltage chip of TI company, the working temperature of TL431C delegate parts of an apparatus is 0 degrees reach 70 degrees (civil class) , the working temperature of TL431I delegate parts of an apparatus is – 40 degrees reach 85 degrees (industrial level) , among them the working temperature that suffixal “C” and “I” differ with respect to the delegate.

 

3, divisional parts of an apparatus encloses a form

 

For instance the TL431 of fiducial voltage chip of TI company, what TL431CP represents is PDIP is enclosed, what TL431CD represents is SOIC is enclosed, among them of suffixal “P” and “D” delegate is different enclose (“C” represents temperature, above had explained) .

 

4, divisional order goods the means that pack

 

For instance, the TL431 CD of fiducial voltage chip of TI company, if the requirement is to press dish of outfit (2500PCS/ dish) purchase, the model that must press TL431 CDR so issues sheet, what the suffixal “R” here represents is dish of outfit. Otherwise, issue sheet by TL431 CD, the likelihood that buys is piping outfitting (75PCS/ is in charge of) stock.

 

5, divisional have lead and without lead

 

For instance, the comparator chip LM393D(“D” of ON company expresses is SOIC encloses) , if want to use the model that do not have lead, must issue sheet by LM393DG, the suffixal “G” here expresses not to have plumbic model, do not have this suffixal have plumbic type namely.

 

Suffixal likelihood still has other and special use, anyhow, suffixal information cannot omit, the likelihood that buys otherwise is not the stock that you want.

 

The prefix of different company and suffixal likelihood are different (a few prepositive and suffixal consistent) that also have a few company, this need reference chooses the particular case of manufacturer actually.

3 digit word – a the registering serial number that represents current semiconductor device, letter adds 2 digit word – the registering serial number that shows special semiconductor device.

 

The 4th part: Undertake dividing shelf to parts of an apparatus of same kind name with the letter.

 

A, B, C, D, E, , , the sign that the parts of an apparatus that shows same type has dividing shelf by some parameter.

 

Outside dividing 4 primary shares, still add sometimes suffixal, in order to distinguish character or farther classification. Common and suffixal as follows:

 

1, of model of stabilized voltage diode suffixal. Its suffixal the first part is a letter, express to stabilize the concessional error limits that voltage is worth, alphabetical A, B, C, D, E states concessional error is ±1% , ±2% , ±5% , ±10% , ±15%; respectively its are suffixal the 2nd part is a number, the 3rd part with the integral and numeric suffixal; that shows nominal and stable tension is alphabetical V, era is decimally, the number after alphabetical V provides the decimal value of nominal and stable voltage for stabilized voltage.

 

2, rectification diode is suffixal it is a number, state the compression of the greatest retrorse peak value of parts of an apparatus is worth, the unit is volt.

 

3, what brilliant brake provides model is suffixal also be a number,

 

Normally compression of the greatest retrorse peak value is worth line out and the biggest the numeric and lesser that voltage value in closing voltage reversely. Be like: BDX51- expresses dynatron of high-power of NPN silicon low frequency, AF239S- states PNP germanium is high frequency small-power dynatron.
