Infineon Technologies TT330N16AOFHPSA1

Overview

TT330N16AOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial drive systems. It delivers 330 A average on-state current (ITAVM) at TC = 85°C, 1600 V repetitive peak off-state voltage (VDRM/VRRM), and features pressure-contact die attachment for thermal reliability. Used in soft starters, static switches, and UPS rectifiers where robust surge handling and low conduction loss are critical.

For engineers reviewing the TT330N16AOFHPSA1 datasheet, TT330N16AOFHPSA1 pinout, TT330N16AOFHPSA1 application, or TT330N16AOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.106 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (≤200 mA), and crowbar-capable surge current (12.5 kA).

Technical Context

This dual-thyristor module operates in phase-controlled AC power circuits, enabling precise firing-angle control for voltage regulation and motor speed control. Its pressure-contact construction ensures stable thermal performance under high di/dt (250 A/µs) and dv/dt (1000 V/µs) transients, with insulated base plate supporting Class I safety isolation per IEC61140.

The device supports both two-pulse (B2) and six-pulse (B6) bridge configurations, with validated derating curves for ITAVM up to 330 A across conduction angles from 30° to 180°. Thermal transient impedance ZthJC data enables accurate junction temperature prediction under pulsed load conditions.

FAQ

What is the maximum allowable junction temperature for TT330N16AOFHPSA1?

The maximum junction temperature (Tvj max) is 130°C, as specified in the Infineon technical information document revision 3.5. This limit governs thermal design margins and must be maintained under all operating conditions-including worst-case ITAVM, ambient temperature, and heatsink resistance-to ensure long-term reliability and avoid thermal runaway.

Does TT330N16AOFHPSA1 require a heatsink, and what is the recommended mounting torque?

Yes, active heatsinking is mandatory: RthJC is 0.106 K/W per arm, and power dissipation exceeds 100 W at rated ITAVM. Mechanical mounting torque for the M1 screws is 5 Nm ±15%, and for M2 terminal screws it is 12 Nm ±10%, as defined in the mechanical properties section of the datasheet.

Can TT330N16AOFHPSA1 be used in a six-pulse (B6) rectifier configuration?

Yes-it is explicitly validated for B6 bridge operation, with published derating curves for ITAVM up to 330 A at 180° conduction angle and total circuit power dissipation charts covering RthCA from 0.10 to 2.00 K/W. Gate drive must be synchronized across all six arms using isolated trigger sources.

What is the gate trigger voltage and current specification at maximum junction temperature?

At Tvj = 130°C, the maximum gate trigger voltage (VGT) is 2 V and maximum gate trigger current (IGT) is 200 mA, measured at vD = 12 V. These values define the minimum driver capability required to ensure reliable turn-on under worst-case thermal and voltage conditions.
