Safe Operating Guidelines:

Follow these guidelines to safely operate the transistor:

• Always operate the transistor at least 20% below from its absolute maximum ratings.
• The max collector-emitter voltage is 25V but by following the above guideline we will not drive load of more than 20V.
• The max collector current is -500mA but we will not drive load of more than -400mA.
• Always check pin layout before using in the circuit.
• The storage and operating temperature should be between -55°C to 150°C.
