What is the current gain value of BC 148 transistor?
The hFe (current gain) on the BC148 ranges from a minimum value of 20 to 100, depending on collector current, with a maximum value of 300.
What is meaning of BC in BC107 transistor?
in bc107 transistor b stands for the material i.e,silicon here and c stands for af low power signal
Range of currentgain of bc 107 transistor?
the dc current gain of BC107 can vary from 110 to 450
Is active is a cutoff region of transistor?
The active region of a transistor is when the transistor has sufficient base current to turn the transistor on and for a larger current to flow from emitter to collector. This is the region where the transistor is on and fully operating.
Different between power transistor and transistor that used in small signal?
Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.
What is the substitute for BC 212 transistor?
2n3906 pnp
What is the current gain value of BC 148 transistor?
The hFe (current gain) on the BC148 ranges from a minimum value of 20 to 100, depending on collector current, with a maximum value of 300.
BC in integrated circuits stands for what?
BC stands for silicon transistor
Bc stands fo what in transistor?
base to collector
Can fet be used as a transisitors?
No. The Field Effect Transistor is a different technology than the Bipolar Junction Transistor. That cannot substitute for one another.
Function of transistor BC 558 in musical bell?
it cnverts to a low voltage.
Why BC 107 is most widely used transistor?
They are known to be the most reliable transistors.
What is meaning of BC in BC107 transistor?
in bc107 transistor b stands for the material i.e,silicon here and c stands for af low power signal
When did Macedonia come under roman rule?
It was defeated in the 4th Macedonian war in 148 BC, it became a Roman province in 146 BC
When did Greece conquer the Romans?
The Kingdom of Macedon was annexed in 148 BC. The whole of mainland Greece was annexed in 146 BC. Crete was annexed in 76 BC, during a war against piracy.
Range of currentgain of bc 107 transistor?
the dc current gain of BC107 can vary from 110 to 450
What is description of bc147 transistor?
This is the European "Pro-electron" numbering system compared with the US JEDEC system (2N etc)First - LetterA = Germanium DeviceB = Silicon DeviceC = Gallium ArsenideSecond - Letter for A/B/C devicesA = small signal diodeC = small signal general purpose transistor (for audio or slow speed switching)D = power transistor (audio and low frequency applications_F = small signal RF transistorT = SCR / ThyristorU = power transistor for switching applicationsY = rectifier diodeThird + Fourth + Fifth - Unique identifier numberSome manufacturers put some significance on the number. For example Mullard/Philips treated the second digit of 4 meaning NPN Lockfit case and 5 meaning PNP lockfit. Many used 6 for TO92 cases.An optional letter followed indicating a gain grouping ... typically A being lowest, B middle and C highestDifferent manufacturers created similar transistors with different type markings.e.g. BC107 BC167 all functionally very similar.So, the BC147 is a Silicon small signal audio transistor with a "Lockfit case" originally manufactured by/for Philips/Mullard. A viable replacement today, if you can't find a 147 is a BC547 If there's a gain grouping letter, you need to match the gain grouping either by a comparable letter, or by testing. Careful with the pinout.There are a cluster of similar transistors ...So, the BC147 is one of a cluster of 3 similar transistors ... BC147/148/149. BC147 has ratings of VCE 50, VCB 45 ICMAX 100 hfe 125-500BC148 has ratings of VCE 30, VCB 20 ICMAX 100 hfe 125-500BC149 has ratings of VCE 30, VCB 20 ICMax 100 hfe 240-900 Noise 2dBLockfit transistor pinout (wideface down)BE CBC547 pinout (flatface down)E B C
