2SA1943 PNP and 2SC5200 NPN is a transistor matching for audio power because it has the capability of a large current (IC = 15A) and the transition frequency is high (typically fT = 30 MHz), ideal for use in applications amplifier audio output high fidelity (Hi-Fi Audio Power Amplifier Output) powered 100 Watt RMS.
Complementary transistors can also be used at Darlington Pair configuration for amplifier applications (general purpose amplifier) hinggaPD (max) = 150 Watt DC (at 25 ° C, decreasing linearly by 1,04W per increase of 1 ° C). Typical capacitance at the collector terminal of 360 pF to 200 pF for the 2SA1943 and 2SC5200.
The potential difference between Terninal collector with terminal base or emitter can reach up to 230 Volt, between base with emitter 5 Volt, hFE (power gain) between 55 ~ 160 (grade R) for each transistor at VCE = ± 5V and IC = ± 1A.
Toshiba-made transistor is packaged in 2-21F1A (body size of 20.5 x 26 x 2.8 mm, weight 9,75g, long terminal pin 20 mm, width of 1mm, the distance between pins of 5.45 mm).
