Infineon Technologies TT260N22KOFHPSA1

Overview

TT260N22KOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching in industrial power converters. It delivers 260 A average on-state current at TC = 85 °C, 2200 V repetitive peak off-state voltage (VDRM/VRRM), and features pressure-contact construction with electrically insulated base plate for crowbar, soft starter, and UPS rectifier applications.

For engineers reviewing the TT260N22KOFHPSA1 datasheet, TT260N22KOFHPSA1 pinout, TT260N22KOFHPSA1 application, or TT260N22KOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.113 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (≤200 mA), and surge current capability (8000 A, 10 ms).

Technical Context

This dual-thyristor module operates in B2 (two-pulse) and B6 (six-pulse) bridge configurations, supporting phase-angle control of AC mains-fed loads. Its pressure-contact die attachment ensures low parasitic inductance and stable thermal performance under repetitive surge conditions up to 8 kA.

The device integrates two inverse-parallel thyristor arms in a single industrial-standard package with AlN-based electrical isolation. Gate drive requirements are defined by triggering voltage ≤2 V and threshold voltage ≤0.85 V, enabling compatibility with standard pulse transformers and optocoupled drivers.

FAQ

What is the maximum allowable junction temperature for TT260N22KOFHPSA1?

The maximum junction temperature (Tvj max) is 125 °C, as specified in the thermal characteristics section. Operation beyond this limit risks irreversible degradation of the silicon die and pressure-contact interface. Thermal design must ensure that junction temperature remains below 125 °C under worst-case conduction and surge conditions, using the provided ZthJC transient impedance curves and RthJC value of 0.113 K/W.

Can TT260N22KOFHPSA1 be used in a single-phase B2 bridge configuration?

Yes - TT260N22KOFHPSA1 contains two inverse-parallel thyristor arms and is explicitly rated for B2 (two-pulse) bridge operation, as confirmed in the "Maximaler Strom bei B2 und B6" diagrams. It supports up to ~1400 A output current with appropriate heatsinking and RthCA ≤ 0.25 K/W, making it suitable for high-power single-phase rectifiers and soft starters.

What gate drive requirements must be met for reliable triggering?

Each gate (G1/G2) requires ≤200 mA trigger current and ≤2 V trigger voltage at 25 °C with 12 V anode-cathode voltage. The gate characteristic curve shows valid triggering within the shaded region bounded by vG = f(iG); minimum pulse width is 20 µs. Exceeding PGM limits (e.g., 150 W/0.1 ms) risks gate damage.

Is the baseplate electrically isolated, and what is its isolation rating?

Yes - the baseplate incorporates aluminum nitride (AlN) ceramic insulation rated for 3.6 kV RMS (1 second, 50 Hz), meeting Class I insulation per EN 61140. This allows direct mounting to grounded heatsinks without supplemental insulation, simplifying mechanical integration and improving thermal coupling in industrial enclosures.
