Instructions for Use:
- Handling: The 1N4448HWT-7 is sensitive to electrostatic discharge (ESD). Use proper ESD protection measures when handling the device.
- Mounting: Ensure that the device is mounted with adequate thermal management if it will be operating at high currents or in high ambient temperatures.
- Soldering: Use a soldering iron with a temperature not exceeding 300°C for a duration not exceeding 10 seconds. Avoid excessive heat which can damage the diode.
- Polarity: Ensure correct polarity during installation. The cathode (marked band) should be connected to the more positive side of the circuit.
- Derating: For continuous operation at temperatures above 25°C, derate the forward current by 1.5 mA per degree Celsius above 25°C.
- Storage: Store the diodes in a dry, cool place away from direct sunlight and sources of heat.
- Testing: When testing the diode, use a multimeter set to the diode test mode to check for proper forward and reverse characteristics.
