⚠️ Important Selection & Installation Guidelines
1. Module Selection — Current Margin
The rated current on the module is the average on-state value, not the effective long-term operating current. Always apply the appropriate safety margin based on your load type:
- Resistive Load: Actual current (A) × 2 to 2.5 = Required module nominal current (A)
- Inductive Load: Actual current (A) × 6 to 7 = Required module nominal current (A)
2. Heat Sink Requirement
If the actual working current of the device exceeds 5A, a suitable heat sink must be fitted to prevent thermal damage and ensure stable long-term operation.

Frequently Asked Questions
Q: What is a PD Thyristor SCR Module and how does it work?
A: A PD Thyristor SCR (Silicon Controlled Rectifier) Module is a solid-state switching device used to control electrical power flow in a circuit. It can be triggered into conduction by a gate signal and remains conducting until the current drops below a holding threshold. These modules are widely used in motor control, rectifier power supplies, industrial heaters, and more.
Q: Which current and voltage rating should I choose for my application?
A: Always select a module with a higher nominal current than your actual load current. For resistive loads, multiply your actual current by 2–2.5 to determine the required module current rating. For inductive loads (motors, coils, transformers), multiply by 6–7. For voltage, choose a rating that exceeds your maximum circuit voltage — 1200V or 1600V options are available.
Q: Do I need a heat sink with this thyristor module?
A: Yes. If your actual working current exceeds 5A, a properly rated heat sink is required. Without adequate cooling, the module may overheat, reducing performance or lifespan. Always match the heat sink thermal resistance to the power dissipation of your specific application.
Q: Are bulk quantities available, and what is the lead time?
A: Standard models are kept in stock and available for immediate shipment. For bulk orders, please contact customer service with your quantity requirements to confirm delivery schedules and pricing.
Q: What are the compatible model numbers for this thyristor module?
A: This listing covers a range of compatible models including PD110FG160, PD130FG160, SCE200AA160, PD70FG, and PD55FG120, spanning current ratings from 25A to 200A and voltage ratings of 1200V and 1600V.
