Description
| The 2SA1943-O is a diffused-junction silicon PNP transistor designed to deliver high performance in power applications. With a VCEO breakdown voltage of 230 V, a collector current of up to 15 A and a power dissipation of 150 W, it is a perfect match for audio amplifier circuits, linear power supplies and general-purpose high-current applications.
The carefully selected “O” gain class ensures stability and consistency from batch to batch, making this transistor ideal for push-pull configurations paired with its complementary 2SC5200-O. It offers a low saturation voltage (0.5 V typical), a transition frequency of 30 MHz and a low output capacitance, for fast response and high efficiency. The TO-264 package, with its large heat-dissipating surface, also makes it suitable for heavy thermal loads. |
