Instructions for Use:
General Handling:
- Storage: Store in a dry, cool place away from direct sunlight and extreme temperatures.
- Handling: Handle with care to avoid damage to the leads and body. Use appropriate ESD protection.
Mounting:
- Through-hole Mounting: Ensure proper alignment and secure mounting using appropriate tools and techniques.
- Thermal Management: Use a heatsink if necessary to manage thermal dissipation, especially under high current conditions.
Electrical Connections:
- Anode (A): Connect to the positive side of the circuit.
- Cathode (K): Connect to the negative side of the circuit.
- Gate (G): Apply the trigger signal to this terminal to turn on the thyristor.
Operating Conditions:
- Voltage and Current Ratings: Do not exceed the maximum RMS voltage and current ratings.
- Surge Current: Ensure that the peak surge current does not exceed 600 A for more than 8.3 ms.
- Temperature: Operate within the specified temperature range to avoid thermal stress and potential failure.
Gate Triggering:
- Trigger Current (Igt): Apply a minimum of 50 mA to the gate to ensure reliable triggering.
- Trigger Voltage (Vgt): The gate trigger voltage should be at least 1.5 V.
Holding Current:
- Minimum Holding Current (Ih): Maintain a minimum current of 5 mA through the thyristor to keep it in the conducting state.
Safety Precautions:
- Isolation: Ensure proper isolation to prevent electrical shock.
- Overvoltage Protection: Consider using overvoltage protection devices to safeguard against transient voltages.
- Cooling: Monitor the temperature of the device and use adequate cooling methods to prevent overheating.
