Infineon TT320N16SOFHPSA1, Thyristor Module 1.6 kV 9.5 kA, 320 A 150 mA 1.47 V 7-Pin

This thyristor module is a high-voltage power semiconductor device designed to control large currents in demanding electrical systems. It operates at elevated junction temperatures and is intended for applications requiring substantial on-state current handling and strong transient tolerance.

• Repetitive Peak reverse withstand of 1600V aids high-voltage switching
• Rated average on-state current 320A supports continuous load handling
• Surge current capability 9500A absorbs severe transient events
• Maximum operating temperature 130°C allows elevated-temperature operation
• Low gate trigger voltage 2V enables sensitive gate-drive requirements
• Holding current 150mA ensures stable latch behaviour under low currents

• Suitable for high-voltage industrial power conversion systems
• Ideal for heavy-duty motor control and soft-start circuits
• Used with high-energy Pulse and surge protection equipment
• Can be used for bulk power switching in renewable installations
• Appropriate for utility-scale rectification and inverter modules

The gate requires a trigger drive that does not exceed 2V and can supply up to 150mA to ensure reliable turn-on.

It can withstand surge currents up to 9500A for short durations without immediate failure, provided thermal limits are respected.

Repetitive Peak off-state leakage is 60mA when the device is subjected to its maximum reverse voltage.

Continuous operation is intended at temperatures up to 130°C, sustained operation beyond this risks performance degradation.

The package exposes seven electrical pins for mounting and circuit interfacing.
