Features:
- Combines a phase-control thyristor and diode in one 1600 V insulated power block.
- Carries 330 A average on-state current when case temperature remains at the specified condition.
- Transfers semiconductor losses through an isolated baseplate secured by the documented mounting torque.
Infineon TD330N16KOF separates its high-current power terminals from the low-energy gate connection.
The thyristor controls the conduction interval while the diode completes the specified rectifier arrangement.
Electrical loss, thermal resistance and heat-sink contact must be evaluated as one operating system.
The Infineon TD330N16KOF 1600 V 330 A Thyristor/Diode Power Module is listed by the OEM as active and preferred.

Thyristor–Diode Conduction Sequence
- Controlled arm: A gate pulse starts current in the thyristor arm at the selected point in the AC cycle.
- Uncontrolled arm: The diode conducts according to circuit polarity and does not require a separate trigger.
- Off-state duty: The repetitive blocking rating applies while the relevant semiconductor arm is not conducting.
- Current classes: Continuous average current and short non-repetitive surge current describe different loading intervals.
Heat Flow from Junction to Heat Sink
- Conduction loss: Threshold voltage and slope resistance combine with the load waveform to determine on-state loss.
- Dual heat source: The thyristor and diode junctions contribute heat to the common module base.
- Insulated transfer: Heat crosses the electrically insulated baseplate before entering the external heat sink.
- Interface pressure: Correct mounting torque keeps the baseplate in uniform contact with the thermal interface material.
- Junction limit: The completed cooling path must hold both semiconductor junctions within the specified temperature boundary.
Trigger and Transient Coordination
- Gate drive: The trigger circuit must provide the documented gate current and voltage between gate and cathode.
- Cathode reference: The control connection is electrically distinct from the main terminals but remains referenced to the thyristor cathode.
- Current rise: Circuit inductance and drive timing must keep turn-on di/dt within the device limit.
- Voltage rise: The surrounding snubber and commutation network must keep off-state dv/dt within its separate limit.
Mechanical and Electrical Interfaces
- Heat-sink face: The isolated baseplate requires a flat, clean mounting surface and an even thermal interface.
- Base fastening: Mounting hardware is tightened to 5 Nm to establish the specified mechanical contact.
- Power joints: Main-current conductors use the larger terminals and the separate 12 Nm terminal torque.
- Control tabs: Gate and auxiliary wiring connect through the 2.8 x 0.8 mm flat terminals rather than the power studs.
