BC328 PNP Transistor

• BC328 is a TO-92 package PNP bipolar junction transistor (BJT) designed to use in general purpose applications. The transistor is having very good specs due to which it can be used in wide variety of applications. For example, it can handle load of upto 800mA which is quite a good capability for this small TO-92 package because most of the TO-92 packages not have that much current handling capability, therefore this feature makes this transistor an ideal TO-92 package transistor to drive high current loads as compared to most other transistors which comes in the same package. Another good feature is its DC current gain of up to 630 which makes it ideal to use in applications in which we want to amplify low gain signals. Moreover, the 100MHz transition frequency also makes it a good transistor to use in RF applications such as FM radios and FM senders etc. Looking at the absolute maximum ratings of the transistor the maximum collector-emitter voltage(VCEO) of the transistor is -25V, max collector current is -800mA, the max emitter-base voltage is -5V, and max collector power dissipation is 625mW.
• The transistor is available in three different versions according to its DC current gain and can be selected according to your application gain requirements. The gain value of each transistor can be determined by the two digit code number written after the part number. If these two numbers are “16” then the gain of the transistor will be 100 to 250, if it is “25” then the gain of the transistor will be 160 to 400 and if “40” then the gain of the transistor will be 250 to 630.
