Infineon Technologies TD260N22KOFHPSA1

Overview

TD260N22KOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial drive systems. It delivers 260 A average on-state current at 85 °C case temperature, 2200 V repetitive peak off-state voltage, and features pressure-contact die attachment for thermal and mechanical robustness in static power controllers.

For engineers reviewing the TD260N22KOFHPSA1 datasheet, TD260N22KOFHPSA1 pinout, TD260N22KOFHPSA1 application, or TD260N22KOFHPSA1 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 insulated baseplate construction for safe mounting in grounded heatsink configurations.

Technical Context

This dual-thyristor module operates in B2 (two-pulse) and B6 (six-pulse) bridge topologies with symmetrical forward/reverse blocking capability up to 2200 V. Its pressure-contact silicon pellet structure enables stable conduction under high di/dt (250 A/µs) and high I²t surge tolerance (320,000 A²s at T_{vj max}).

The module integrates electrically isolated aluminum nitride (AlN) baseplate insulation per IEC 61140 Class 1, supporting direct mounting without additional insulators. Thermal performance is characterized by transient Z_thJC curves and DC R_thJC = 0.113 K/W per arm, enabling precise junction temperature estimation in soft-start and crowbar applications.

FAQ

What is the maximum allowable junction temperature for TD260N22KOFHPSA1?

The maximum junction temperature (T_{vj max}) is 125 °C, as specified in the thermal characteristics section of the official technical information document. This limit applies under all operating conditions including surge events and must be maintained via proper heatsink design and thermal interface management to ensure long-term reliability and prevent thermal runaway.

Does TD260N22KOFHPSA1 require external gate resistors for standard operation?

No external gate resistor is required for basic triggering, as the device specifies gate trigger current ≤200 mA and gate trigger voltage ≤2 V at 25 °C. However, a series gate resistor (typically 10–47 Ω) is recommended to limit peak gate current during fast dv/dt events and improve noise immunity in noisy industrial environments per Infineon's application note AN2012-05.

Can TD260N22KOFHPSA1 be used in single-phase applications?

Yes-it supports single-phase B2 (two-pulse) bridge configurations, as confirmed by its maximum output current curves for L-load and R-load in the datasheet. In single-phase soft starters, it delivers up to 1400 A peak current with appropriate thermal derating and gate drive synchronization to the AC zero-crossing point.

What is the creepage distance and why does it matter for this module?

The creepage distance is 17 mm, measured across the insulated baseplate surface between high-voltage terminals. This value ensures compliance with IEC 61800-5-1 for functional insulation in drive systems operating at 1000 V AC mains, preventing tracking failure under humid or contaminated conditions in factory environments.
