Infineon TT120N16SOFHPSA1, Thyristor Module 1600 V 2.25 kA, 120 A 100 mA 1.75 V 7-Pin

Infineon TT120N16SOF Series Thyristor Module, 1600V Repetitive Peak Reverse Voltage, 120A Rated Average On State Current - TT120N16SOFHPSA1

This thyristor module is a high-voltage semiconductor device designed to control large AC or DC currents in power conversion and switching applications. It operates within elevated thermal environments and provides a controlled on-state for managing heavy current flow while withstanding substantial reverse and off-state conditions.

Features and Benefits:

• Repetitive Peak reverse withstands 1600V for high-voltage use
  Rated average on-state current 120A enables sustained current handling
  Surge current capability 2250A copes with transient overloads
  Low gate trigger voltage 2.5V simplifies drive circuitry
  Holding current 250mA ensures stable latching at low currents
  Peak on-state voltage 1.75V minimises conduction losses

Applications

• Suitable for high-voltage rectifier module assemblies
  Ideal for power conversion in industrial drives
  Used for controlled switching in surge-prone systems
  Can be used for heavy-current inverter stages
  Suitable for non-automotive high-voltage power supplies

What gate drive requirements are indicated for reliable triggering?

A gate drive capable of delivering up to 100mA with a trigger voltage at or above 2.5V is required to ensure consistent turn-on behaviour.

How does the device behave under short-term overloads?

It can tolerate surge events up to 2250A, providing brief protection against transient high-current conditions while maintaining average conduction at 120A.

What off-state leakage should designers account for?

Repetitive Peak off-state current is specified at 20mA, which should be considered when designing guarding and sensing circuits.

What thermal operating limit must system cooling respect?

The maximum permitted junction temperature is 130°C, so cooling strategies must maintain temperatures below this threshold for reliable operation.
