Infineon Technologies TT430N22KOFHPSA2

Overview

TT430N22KOFHPSA2 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial power electronics. It delivers 430 A average on-state current (ITAVM) at TC = 85 °C, 2200 V repetitive peak off-state voltage (VDRM/VRRM), and features pressure-contact Si-pellet construction with electrically insulated baseplate. It is deployed in soft starters, static switches, and battery charger rectifiers requiring robust thermal performance and high surge immunity.

For engineers reviewing the TT430N22KOFHPSA2 datasheet, TT430N22KOFHPSA2 pinout, TT430N22KOFHPSA2 application, or TT430N22KOFHPSA2 equivalent, key selection criteria include junction-to-case thermal resistance (0.062 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (≤250 mA), and pre-applied TIM option for enhanced thermal interface reliability.

Technical Context

This dual-thyristor module operates in phase-controlled AC circuits using gate-triggered conduction with latching current ≥1500 mA and holding current ≤300 mA. Its 125 °C maximum junction temperature and 14 kA non-repetitive surge current (ITSM) support short-circuit tolerant operation in motor drives and crowbar protection systems.

The module employs Advanced Medium Power Technology (AMPT) with AlN-based internal insulation and pressure-contact die attachment, enabling stable RthJC of 0.062 K/W per module under DC conditions and 0.065 K/W at 180° conduction angle. Its 3.0 kV RMS insulation test voltage ensures safety in grounded industrial equipment.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum allowable case temperature (TC) is +125 °C, validated per IEC 61140 insulation standards and confirmed in thermal derating curves for ITAVM at 180° conduction angle. Operation above this temperature risks irreversible degradation of the AlN insulation layer and pressure-contact interface.

Does TT430N22KOFHPSA2 support forced-air or liquid cooling?

Yes - the module's 0.062 K/W RthJC and 60 mm insulated baseplate are compatible with both forced-air heatsinks (RthCA ≥0.12 K/W) and liquid-cooled cold plates (RthCH ≤0.0075 K/W with TIM). Thermal performance data for rec/sin wave loads is provided in Figures 7–8 of the official technical information document.

How is gate drive isolation implemented in this module?

Gate terminals G1/G2 are galvanically isolated from the baseplate and main power terminals via internal PCB traces and reinforced insulation barriers. The module meets 3.0 kV RMS insulation test requirements at 50 Hz for 1 minute, ensuring safe low-voltage gate control in grounded industrial systems.

Can TT430N22KOFHPSA2 be used in single-phase versus three-phase topologies?

Yes - its dual-arm architecture supports both single-phase B2 bridges and three-phase B6 configurations. Derated current limits (e.g., 1200 A ID for B6 at RthCA = 0.05 K/W) are explicitly plotted in Figure 8, confirming suitability for either topology when thermal design aligns with published ZthJC transient models.
