Instructions for Use:

1. Handling and Storage:

   • Handle the transistors with care to avoid mechanical damage.
   • Store in a dry, cool place within the specified storage temperature range.

2. Mounting:

   • Ensure proper heat sinking to maintain operating temperatures within the specified range.
   • Use insulated mounting hardware if the transistor case is electrically isolated from the circuit.

3. Biasing:

   • For 2SA1695 (PNP), apply a positive voltage to the emitter relative to the base and collector.
   • For 2SC4468 (NPN), apply a positive voltage to the collector relative to the base and emitter.

4. Protection:

   • Use appropriate overvoltage and overcurrent protection circuits to prevent damage.
   • Consider adding a reverse-biased diode across the collector and emitter to protect against inductive spikes.

5. Testing:

   • Test the transistors using a multimeter or transistor tester to ensure they meet the specified parameters.
   • Check for proper biasing and operation in the circuit.

6. Circuit Design:

   • Refer to the datasheets for detailed circuit design considerations, including recommended biasing networks and load configurations.

7. Safety:

   • Always follow safety guidelines when working with high voltages and currents.
   • Use appropriate personal protective equipment (PPE) as needed.

By following these instructions, you can ensure optimal performance and longevity of the 2SA1695 and 2SC4468 transistors in your applications.
