⚠️ Important Selection Guidelines
1. Choosing the Right Current Rating
The current rating printed on the module represents the average on-state current — not the continuous RMS operating value. Always allow generous headroom based on your actual load conditions:
- Resistive loads: Multiply actual current (A) × 2 to 2.5 = required module nominal current
- Inductive loads: Multiply actual current (A) × 6 to 7 = required module nominal current
2. Heat Sink Requirement
When operating at currents above 5A, a suitable heat sink must be installed to ensure safe, stable performance. Do not operate at higher currents without proper thermal management.
Common Applications
- AC motor speed control
- Industrial heating element regulation
- Light dimming and switching circuits
- Power factor correction systems
- Soft-start circuits and AC switching relays

Frequently Asked Questions
Q: What is the difference between a thyristor and a TRIAC bidirectional thyristor module?
A: A standard thyristor (SCR) conducts current in only one direction, making it suitable for DC or half-wave AC applications. A bidirectional thyristor — also called a TRIAC — can conduct in both directions, making it ideal for full AC waveform switching and control in applications like motor drives, dimmers, and heaters.
Q: Do I need a heat sink with this thyristor module?
A: Yes. For operating currents above 5A, a properly rated heat sink is required. Running the module without adequate thermal management at higher currents can cause overheating and reduce the module's lifespan or trigger failure.
Q: How do I select the correct current rating for my application?
A: Use the recommended derating guidelines: for resistive loads, multiply your actual operating current by 2–2.5x to get the required module nominal current rating. For inductive loads (motors, solenoids, transformers), apply a 6–7x multiplier to ensure reliable, safe operation.
Q: Is the KP100.58 / M220.58 packaging compatible with standard mounting hardware?
A: Yes. The KP100.58 and M220.58 are standard industrial module packaging formats widely used in power electronics. They are compatible with common mounting brackets and heat sink configurations used in control panels and power boards.
