Additional Details

The 2SA1283 is typically used in complementary pairs with NPN transistors in audio amplifier circuits. It requires appropriate heat sinking to manage its power dissipation. The transistor's voltage and current ratings must be considered when designing the amplifier circuit. The package type is often a TO-3P or similar through-hole package. It is important to use proper biasing techniques to ensure stable operation and minimize distortion. It should be handled carefully to avoid electrostatic discharge (ESD) damage. The transistor's characteristics are crucial for achieving the desired amplifier performance. This device is now considered obsolete, so replacement/alternate components may be required for new designs. Its fT is around 30MHz. It has a VCE of -180V.
