Instructions for Use:

1. Mounting:

   • Ensure the transistor is securely mounted on a heatsink if operating near maximum power dissipation.
   • Use mica insulators and thermal compound between the transistor and heatsink to ensure good thermal transfer while maintaining electrical isolation.

2. Biasing:

   • For the PNP (2SA1294), connect the emitter to the positive supply, with the collector connected to the load.
   • For the NPN (2SC3263), connect the emitter to ground, with the collector connected to the load.

3. Protection:

   • Incorporate fast-acting fuses in series with the collector lead to protect against short circuits.
   • Consider using transient voltage suppressors (TVS) or Zener diodes across the collector-emitter junction to protect against voltage spikes.

4. Handling:

   • Handle these devices with care to avoid mechanical damage.
   • Follow proper ESD (Electrostatic Discharge) precautions to prevent damage from static electricity.

5. Testing:

   • Before installing into the final circuit, test the transistors using a curve tracer or multimeter to verify functionality.
   • Ensure that all connections are secure and correct to prevent potential damage during operation.

6. Storage:

   • Store in a dry, cool place away from direct sunlight and sources of heat.
   • Keep in original packaging until ready for use to minimize exposure to environmental contaminants.
