Instructions for Use:
Mounting:
- Ensure that the leads are bent to fit the PCB or breadboard spacing.
- Solder the diode quickly to avoid overheating. The maximum soldering temperature is 260°C for 10 seconds.
Circuit Design:
- Connect the cathode (shorter lead or banded end) to the positive side of the circuit.
- Connect the anode (longer lead) to the negative side of the circuit.
- Use a series resistor to limit the current through the diode to a safe level, typically around 10% to 20% of the maximum zener current (Izmax).
Heat Dissipation:
- Ensure adequate heat dissipation if operating near the maximum power rating.
- Consider using a heatsink if continuous operation at high power is required.
Storage:
- Store in a dry, cool place away from direct sunlight.
- Handle with care to avoid mechanical damage to the glass body.
Testing:
- Test the diode using a multimeter set to the diode test mode.
- The diode should show a low resistance in one direction and a high resistance in the reverse direction.
Safety:
- Do not exceed the maximum ratings specified in the table.
- Use appropriate fuses or current-limiting resistors to protect the circuit from overcurrent conditions.
