Infineon Technologies TD330N16KOFTIMHPSA1

Overview

TD330N16KOFTIMHPSA1 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 at 85°C case temperature, 1600 V repetitive peak off-state voltage, and features pressure-contact die attachment for thermal and mechanical robustness. Used in soft starters, static switches, and UPS rectifiers where high surge immunity and reliable forced-commutation are required.

For engineers reviewing the TD330N16KOFTIMHPSA1 datasheet, TD330N16KOFTIMHPSA1 pinout, TD330N16KOFTIMHPSA1 application, or TD330N16KOFTIMHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.106 K/W per arm), critical dv/dt rating (1000 V/µs), gate trigger current (≤200 mA), and pre-applied thermal interface material (TIM) integration.

Technical Context

This dual-thyristor module implements a B6 six-pulse bridge configuration with electrically insulated baseplate and pressure-contact silicon pellet mounting. Its 130°C maximum junction temperature, 12500 A non-repetitive surge current (10 ms), and 250 µs typical turn-off time support controlled commutation in medium-voltage motor drives and crowbar protection circuits.

The module uses Advanced Medium Power Technology (AMPT) and supports both sinusoidal and rectangular conduction angles (30°–180°). Thermal performance is characterized by analytical ZthJC transient impedance data and includes separate derating curves for DC, rectified, and sinusoidal load conditions.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum allowable case temperature (TC) is +130°C, as defined by the device's thermal design limits and junction temperature rating (Tvj max = 130°C). Derating curves in the datasheet show that at TC = 85°C, the module supports 330 A ITAVM; operation above 85°C requires linear current derating per the published ITAVM vs. TC graph.

Does TD330N16KOFTIMHPSA1 require external gate resistors?

Yes - external gate resistors are required to limit peak gate current and ensure reliable triggering. The datasheet specifies maximum gate trigger current IGT ≤ 200 mA and gate trigger voltage VGT ≤ 2 V at 12 V anode-cathode voltage. Typical designs use 10–22 Ω series resistors with pulse transformers or opto-triggers to meet these constraints.

Can this module be used in a single-phase full-wave rectifier?

Yes - TD330N16KOFTIMHPSA1 contains two independent thyristor arms and can be wired as a single-phase full-wave (center-tapped or bridge) rectifier. Each arm handles one polarity half-cycle; gate signals must be synchronized to the AC input phase with appropriate isolation and timing delay to achieve desired output voltage control.

What is the creepage distance and why does it matter for safety certification?

The creepage distance is 17 mm, measured across the insulated baseplate surface between high-voltage terminals. This value satisfies IEC 61800-5-1 and UL 508 requirements for Pollution Degree 2 environments, enabling direct use in industrial drives without additional slotting or potting - critical for achieving reinforced insulation in Class 1 safety systems.
