Instructions for Use

General Handling:

• Storage: Store in a dry, cool place away from direct sunlight.
• Handling: Handle with care to avoid mechanical damage. Use appropriate ESD protection to prevent damage from static electricity.

Mounting:

• Orientation: Ensure the correct orientation during mounting. The cathode (K) and anode (A) should be connected as specified in the circuit diagram.
• Soldering: Use a temperature-controlled soldering iron. Soldering temperature should not exceed 260掳C for more than 10 seconds. Allow the device to cool naturally after soldering.
• Mechanical Stress: Avoid applying excessive mechanical stress to the leads during soldering or handling.

Circuit Design:

• Protection: These diodes are designed to protect circuits from transient voltage spikes. Ensure they are placed close to the sensitive components they are protecting.
• Clamping: The clamping voltage (VC) is the maximum voltage that will be applied to the protected circuit during a transient event. Ensure this value is within the safe operating range of the circuit.
• Current Rating: The peak pulse current (IPP) is the maximum current the diode can handle during a transient event. Ensure the expected surge current does not exceed this rating.

Testing:

• Initial Test: After installation, perform a visual inspection to ensure proper mounting and soldering.
• Functional Test: Apply a known transient voltage to the circuit and verify that the diode clamps the voltage as expected.

By following these guidelines, you can ensure reliable performance and longevity of the KTB817 and KTD1047 TVS diodes in your application.
