2N6491 Transistor Explained / Description:

2N6491 is a general purpose PNP transistor available in TO-220 transistor package. It is designed to be used in general switching and amplifier applications. It is a transistor of a series which also contains other transistors such as 2N6489 and 2N6490.

The transistor has many good features such as high voltage, high collector current, good total power dissipation value, usable in many applications, and availability of its PNP complimentary.

The absolute maximum ratings of the transistor are as follows: the collector-emitter voltage is 80V, continuous collector current is 15A, collector-base voltage is 90V, base current is 5A, emitter-base voltage is 5V, total power dissipation is 75W and operating and junction temperature is -65°C to 150°C.

 

How to Use This Transistor:

The transistor can be used as a switch or amplifier. To use it as a switch first connect its emitter pin with the positive rail of the circuit, apply signals to its base pin through a suitable current limiting resistor (Signals from which you want to control the output load) and connect the load between collector and the negative rail of the circuit.

To use it as an amplifier here we are mentioning a simple amplifier circuit that is mostly used at the output of door bells, toys etc. To make a simple audio amplifier circuit connect its emitter pin with the positive rail of the circuit, apply signals to its base through an electrolytic capacitor (any electrolytic capacitor from 1uF to 10uF) and connect a speaker between collector pin and the negative rail of the circuit.

 

Applications:

Audio amplifiers

Switching Circuit

Motor Drivers

And variety of other general purpose applications

 

Safe Operating Guidelines:

To safely operate the transistor follow these guidelines:

• To get better performance do not drive the transistor to its max values and always stay at least 20% below from these max values.
• The continuous collector current is 15A but by following the above guide we will not drive load of more than 12A.
• The collector-emitter voltage is 80V but we will not drive load of more than 64V.
• Check pin layout before using in the circuit.
• The storage and operating temperature should be from -65°C to 150°C.
