Important Selection & Installation Notes
1. Module Selection & Current Margin
The current rating marked on the module is the average on-state value, not the long-term effective RMS operating value. Always leave sufficient margin based on your actual working environment:
- Resistive loads: Apply a 2–2.5× margin — Actual Current (A) × 2 (to 2.5) = Required Module Nominal Current (A)
- Inductive loads: Apply a 6–7× margin — Actual Current (A) × 6 (to 7) = Required Module Nominal Current (A)
2. Heat Sink Configuration
When the actual operating current exceeds 5A, a properly rated heat sink must be installed to ensure safe and reliable operation and to prevent thermal runaway.
3. Stock & Bulk Orders

Frequently Asked Questions
Q: What is the difference between the SKKT E and SKKT 16E thyristor module variants?
A: The "E" and "16E" suffixes indicate different voltage blocking classifications within the SKKT module series. The 16E typically denotes a 1600V voltage rating. Always verify the exact part number and datasheet for your specific application to ensure the correct voltage and current rating is selected.
Q: Do I need a heat sink for my SKKT thyristor diode module?
A: Yes. If your application draws more than 5A of operating current, a properly rated heat sink is required. Failing to use an adequate heat sink can lead to thermal damage and reduced module lifespan. Ensure the heat sink thermal resistance (°C/W) matches the power dissipation of your selected module rating.
Q: Can this thyristor diode module be used for motor soft-start applications?
A: Absolutely. The SKKT series is well-suited for motor soft-start circuits. When selecting a module for inductive loads such as motors, apply a 6–7× current margin (multiply actual running current by 6 to 7) to determine the appropriate nominal module current rating.
Q: Are bulk orders and custom configurations available?
A: Yes. Standard SKKT module models are available from stock for immediate shipment. For bulk quantities or custom configurations, please contact customer service with your required quantities and specifications to confirm pricing and lead times.
