C2073 NPN Transistor: Datasheet, Pinout and Equivalent

Q: What can be C2073 used for?

C2073 is an NPN 1.5A 150V power transistor used for general purpose power amplifier applications.

Q: How to measure c2073 transistor pin?

The C2073 transistor is of the NPN type. The trademark and model of the transistor face the sequence. 1 is the base, 2 is the collector, and 3 is the emitter (fixed). It can also be measured with a multimeter × 100Ω, the black test lead is connected to one pole, and the red test lead is connected to the other two poles respectively. The indicated resistance values are relatively small (small reverse resistance, large forward resistance), and the black test pen is the base. , The other two poles that have the smallest resistance value are the collector.

Q: Is c2073 the same as a940 transistor?

The parameters are almost the same, but C2073 is NPN, and A940 is PNP, which is often used to drive tubes in power amplifier circuits.

How and Where to Use C2073 Transistor

The C2073 transistor is primarily intended for use in high-power audio amplifier circuits and vertical output circuitry, but it can be utilized in a wide range of other applications as well. Because the transistor's maximum output current is 1.5A, it can drive a wide range of loads under 1.5A, including relays, high-power LEDs, high-power transistors, and any other load that falls within its output current limit.

C2073 Power

The maximum collector current of the transistor is 1.5A, therefore, does not drive a load of more than 1.2A, the max load voltage is 150V, therefore, does not drive a load of more than 120V. The transistor's life is also shortened when an appropriate heatsink is not used, thus always use one. The temperature of storage and operation is also vital to remember, therefore utilize it at temperatures between -55 and +150 degrees Celsius.
