Instructions for Use:

1. Operating Temperature: Ensure the ambient temperature is within the specified range for optimal performance.
2. Mounting: Use appropriate heat sinks if operating near maximum current or voltage to prevent overheating.
3. Biasing: Set up biasing circuits carefully to maintain the transistor within its safe operating area (SOA).
4. Handling: Handle with care to avoid damage from electrostatic discharge (ESD). Use proper anti-static precautions.
5. Testing: When testing, ensure that all parameters do not exceed the maximum ratings listed in the table.
6. Storage: Store in a dry, cool place away from direct sunlight and sources of heat.
