Single Diode Module and Thyristor Module
A single diode module is a passive rectifying device that conducts current automatically when forward-biased, whereas a single thyristor module is an active, controllable switch that requires a gate trigger signal to start conduction.

Single diode module vs single thyristor module, what's their difference?
| Feature | Single Diode Module | Single Thyristor Module (SCR) |
| Terminals | 2 terminals (Anode, Cathode) | 3 terminals (Anode, Cathode, Gate) |
| Control Signal | None required (uncontrolled) | Requires a gate pulse trigger to turn ON |
| Operation | Conducts automatically with forward voltage | Latches ON after a gate pulse; stays ON until current drops below the holding threshold |
| Function | Passive AC-to-DC rectification | Controlled phase-angle power regulation and switching |
| Turn-Off | Natural commutation when voltage reverses | Natural (AC) or forced commutation circuit (DC) |
| Typical Use | Standard power supplies and freewheeling paths | Motor speed control, soft starters, and heating regulators |
