2SA1941 PNP Bipolar Transistor: 10 A, 140 V, 3-Pin TO-3PN, 2SA1941 Equivalents

2SA1941 Pinout

2SA1941 is a PNP  transistor with TO-3P packaging that is designed for high-power audio amplification. It is typically used in conjunction with its NPN  complementary transistor 2SC5198 to create small and large high-power audio amplifiers. When employed as an audio amplifier, the transistor performs well across the entire range of audio frequencies from 20Hz to 20kHz, resulting in good results. It gives the same sound quality at the output with enhanced amplification.

This 2SA1941 transistor is primarily designed for audio amplification; hence it can be utilized in a variety of high and low power audio amplifier final stages. The -10A collector current makes it appropriate for a range of various applications, including switching.

Operate the 2SA1941 transistor  20 percent below its absolute maximum ratings for long-term performance. As a result, do not drive loads greater than -8A and keep the load voltage below 112V. An appropriate heat sink must be used with the transistor, and the transistor must always be stored and operated at temperatures between -55 and +150 degrees Celsius.
