Mounting: Ensure the transistor is securely mounted to prevent mechanical damage. Use appropriate heat sinks if operating near maximum power dissipation limits.
Biasing: Proper biasing of the base-emitter junction is critical for optimal performance. Avoid exceeding the specified base-emitter voltage (VEBO).
Heat Management: Monitor junction temperature to ensure it does not exceed 150°C. Adequate cooling measures should be in place especially under high-power conditions.
Voltage Ratings: Do not exceed the maximum ratings for collector-emitter (VCEO), collector-base (VCBO), and emitter-base (VEBO) voltages to avoid damaging the device.
Current Handling: Keep the collector current within the specified limits to prevent overheating or damage.
Storage Conditions: Store in a dry environment within the storage temperature range (-55°C to 150°C) to maintain reliability.
