TT120N16SOFHPSA1 SCR module 1600V Vdrm 120A Itav pressure contact high surge low loss industrial grade for power control

Features

• 1600V Repetitive Peak Off-State Voltage (Vdrm) – Suitable for high-voltage AC line control (e.g., 380V–480V systems).

• 120A Average On-State Current (Itav) – Handles high continuous load currents with margin.

• Pressure Contact Technology – Ensures reliable connection, excellent thermal cycling endurance, and reduced risk of bond wire fatigue.

• High Surge Current Capability – Withstands inrush and fault currents (typical Itsm > 2kA) for robust protection.

• Low Power Loss – Low on-state voltage (Vtm) improves efficiency in high-current circuits.

• Isolated Baseplate – Simplifies mounting on common heat sinks (rated for 2500V~ isolation typically).

• Industrial Grade Reliability – Designed for continuous operation in harsh environments (wide temp range, vibration resistant).

Applications

• AC Motor Soft Starters – Controlled ramp-up of three-phase induction motors to reduce mechanical and electrical stress.

• Phase Control Rectifiers – AC to DC conversion for battery chargers, electroplating, and DC motor drives.

• Heating Control – Zero-crossing or phase angle control of resistive loads (industrial furnaces, ovens, kilns).

• Static Transfer Switches – Fast switching between power sources for UPS and critical backup systems.

• Lighting Control – Dimming of high-power incandescent or LED lighting in stadiums/theaters.

• Power Supplies – Primary side phase control in high-voltage, high-current regulated supplies.

• Renewable Energy – Crowbar protection and AC switching in wind turbine converters or solar inverters.

Description

The TT120N16SOFHPSA1 is a high-power thyristor (SCR) module from Infineon Technologies, designed for phase control and power switching applications. With a repetitive peak off-state voltage (Vdrm) of 1600V and average on-state current (Itav) of 120A, this module is built for demanding industrial environments. It utilizes pressure contact technology for reliable long-term performance and excellent thermal cycling capability. The isolated baseplate simplifies heat sinking and system assembly. This module is typically used in AC motor controls, soft starters, rectifiers, and power supplies where robust surge handling and low conduction losses are essential.
