Title: Part No. 2SA1302
Introduction:
The 2SA1302 is mainly used in design of amplifiers. Most amplifiers utilize a push-pull circuit like that of Class C amplifier, which involves a NPN transistor and PNP transistor of multiple choices. The 2SA1302 is a PNP Transistor and it also has its corresponding 2SE5201 which is a NPN type transistor. Both these transistors are frequently used together to design high power Amplifiers and also used for fast switching purposes and also in pulse width modulation.
Features:
PNP Transistor having medium power
Range of DC current gain 50 to 155
Collector current continuous is almost 14A
Collector-Emitter voltage is 230 V
Collector-Base voltage is 230V
Emitter Base Voltage is 5.2V
Working:
Ever Since the Transistors work with high-level switching frequency and high collector current, they have a penchant to heat up very fast, hence they are all the time used alongside with a heat sink. Note that the heat sink will also act as the collector pin of the transistor and hence heat sink should be divided from the rest of the circuit. These transistors are mainly used for high powered devices and medium switches.
These transistors are frequently used to build Stereo systems that are rated for 210W or directly above, they can respond to frequency from 5Hz to 100kHz and has a very good sensitivity of 0.75Vrms. There has very fewer signal to noise ratio and less total harmonic distortion making it ideal for audio applications.
Applications:
Collector Voltage is very high approx. 230V
Recommended for high fidelity audio
High current medium power switches
Specially in RF and AF Switches
