CSA1943 AND CSC5200 transistor TO3P(L) CDIL PNP transistor 230V 15A 1- PAIR 2-pcs CDIL CSA1943

Product Overview:

This product listing describes a factory-matched complementary pair (1x PNP, 1x NPN) of heavy-duty silicon power transistors housed in the large-format TO-3P (also referred to as TO-3PL) plastic package. Engineered specifically for high-power, high-fidelity audio output stages, this specific pair is optimized to provide exceptional linearity, high power handling, and low distortion—making them the industry standard for 100-watt to 150-watt premium audio amplifiers and public address (PA) systems.

Core Pair Components:

1. CSA1943: The PNP complementary power transistor.

2. CSC5200: The NPN complementary power transistor.
