MPSA14 Description
The MPSA14 transistor is an NPN Darlington transistor that comes in TO-92 and other tiny packages. A Darlington transistor is a transistor with two transistors packed onto a single chip. These transistors are connected in such a way that the input signal gain is multiplied and increased many times more than the input gain, however, this process also increases the signal's noise.
The transistor's maximum collector current is 500mA, and its maximum collector to emitter voltage is 30V.
The transistor is nearly identical to the MPSA13, with the exception of the DC current gain, which is 5000 in the MPSA13 and 10,000 in the MPSA14.

Trend Analysis
How does MPSA14 operate in safety?
It is recommended that MPSA14 be used 20 per cent below its maximum ratings in a circuit for long-term performance. Because the transistor's maximum collector current is 500mA, don't drive loads that draw more than 400mA. Because the maximum collector to emitter voltage is 30V, never drive a load more than 24V and always store or use the transistor at temperatures between -55°C and +150°C.
What is the PNP Complementary of MPSA14?
The PNP Complementary of MPSA14 is MPS64.
What does the inside of an mpsa14 transistor look like?
The MPSA14 is a PNP Darlington Transistor, meaning it has two NPN transistors inside a single package. The emitter of the first transistor is connected to the base of the second transistor and both the collector pins are clubbed together as shown in the pinouts image.
