Instructions for BD681 DOMESTIC TO-126

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 4.5V to 30V.

2. Current Handling:

   • The continuous collector current (Ic) should not exceed 3.0A.
   • For short durations, the peak collector current (Icm) can be up to 5.0A.

3. Voltage Ratings:

   • The collector-emitter saturation voltage (Vce(sat)) should be between 0.7V and 1.8V.
   • The base-emitter saturation voltage (Vbe(sat)) should be between 1.2V and 2.5V.

4. Temperature Considerations:

   • Store the device in an environment where the temperature ranges from -40°C to 150°C.
   • Ensure the operating junction temperature (Tj) does not exceed 150°C.

5. Mounting:

   • Use appropriate heat sinks if the device will be operating at high currents or temperatures.
   • Ensure proper mechanical mounting to avoid stress on the leads.

6. Handling:

   • Handle the device with care to avoid static damage.
   • Follow standard ESD (Electrostatic Discharge) precautions during handling and installation.

7. Testing:

   • Before final assembly, test the device under typical operating conditions to ensure it meets the specified parameters.

8. Soldering:

   • Use a controlled soldering process to avoid overheating the device.
   • Soldering temperature should not exceed 260°C for more than 10 seconds.

9. Storage:

   • Store the device in a dry, cool place to prevent moisture damage.

10. Compliance:

    • Ensure that the device complies with all relevant safety and regulatory standards for your application.
