Instructions for Use:

1. Mounting:

   • Ensure the transistor is mounted on a heatsink to dissipate heat effectively.
   • Use thermal paste between the transistor and the heatsink to improve thermal conductivity.

2. Wiring:

   • Connect the collector (C) to the high-voltage side of the circuit.
   • Connect the emitter (E) to the low-voltage side or ground.
   • Connect the base (B) to the control signal source.

3. Protection:

   • Use a base resistor to limit the base current and prevent damage to the transistor.
   • Consider adding a flyback diode across the load to protect against inductive spikes.

4. Operating Conditions:

   • Do not exceed the maximum ratings specified in the table.
   • Monitor the junction temperature to ensure it does not exceed 150掳C.

5. Storage:

   • Store the transistor in a dry, cool place away from direct sunlight.
   • Handle with care to avoid static discharge, which can damage the component.

6. Testing:

   • Before installation, test the transistor using a multimeter to check for continuity and proper operation.
   • Ensure all connections are secure and free from short circuits.
