About this product
The 2SA1943 is a PNP high-power bipolar transistor in a SOT-93 metal case. It is intended for high-voltage, high-current linear and audio output stages, and it is the complementary partner of the 2SC5200 NPN transistor. Proper heat sinking is required at high power.

Frequently asked questions
Which transistor is the complement of the 2SA1943?
The 2SC5200 is its NPN complement, commonly used together in push-pull output stages of audio amplifiers.
Do I need a heat sink for this transistor?
Yes, when operating at high power. Mount it on a suitable heat sink with thermal paste, and use an insulating pad if the metal tab is connected to the collector and the heat sink is grounded.
