Bidirectional SCR Thyristor Module 80A 100A 800V 1200V TRIAC
Bidirectional SCR Thyristor Module 80A 100A 800V 1200V TRIAC
Bidirectional SCR Thyristor Module – TG80C80 / TG80C120 / TG100C80 / TG100C120
Engineered for demanding AC power control applications, these bidirectional SCR (TRIAC) thyristor modules deliver reliable switching performance across a wide range of industrial and commercial circuits. Available in four configurations — TG80C80, TG80C120, TG100C80, and TG100C120 — each module is rated for either 80A or 100A forward/reverse current and either 800V or 1200V maximum voltage, giving engineers the flexibility to match the right component to the right application.
Made in China.

⚠️ Important Selection & Usage Reminders
1. Choosing the Correct Current Rating
The rated current printed on the module represents the average on-state current — not the sustained RMS operating current. Always apply an appropriate safety margin based on your actual load and environment:
- Resistive loads: Actual current (A) × 2 to 2.5 = Required module nominal current (A)
- Inductive loads: Actual current (A) × 6 to 7 = Required module nominal current (A)
2. Heat Sink Requirement
When the actual working current of the device exceeds 5A, a properly rated heat sink must be fitted to ensure stable, long-term operation and prevent thermal damage to the module.

Frequently Asked Questions
Q: What is the difference between the TG80C80, TG80C120, TG100C80, and TG100C120 thyristor modules?
A: The model number encodes the key ratings. "TG80" means 80A current capacity; "TG100" means 100A. "C80" means 800V maximum voltage; "C120" means 1200V. Choose based on your circuit's current and voltage requirements, remembering to apply the appropriate safety margin.
Q: Do I need a heat sink with these SCR thyristor modules?
A: Yes — whenever your actual operating current exceeds 5A, a suitable heat sink is required. Operating without adequate thermal management at higher currents can shorten the device's lifespan and may cause failure.
Q: What types of loads are these bidirectional SCR modules suitable for?
A: These TRIAC/SCR modules are suitable for both resistive loads (such as electric heaters and incandescent lighting) and inductive loads (such as AC motors and transformers). Be sure to apply the correct derating factor: 2–2.5× for resistive, 6–7× for inductive loads.
Q: Can I order these thyristor modules in bulk or custom configurations?
A: Yes. Standard models are available in stock for immediate orders. For large quantity purchases or custom specifications, please contact our customer service team to confirm availability and delivery schedule.
