Infineon Technologies TT240N36KOFHPSA1

Overview

TT240N36KOFHPSA1 from Infineon Technologies is a phase-control thyristor module rated for 3600 V repetitive peak off-state voltage (V_DRM/V_RRM), 240 A average on-state current (I_TAVM) at T_C = 85°C, and 6100 A non-repetitive surge current (I_TSM). It features dual thyristor arms in press-pack construction with AlN isolation, designed for high-power AC line commutated rectification and motor speed control in industrial medium-voltage drives.

For engineers reviewing the TT240N36KOFHPSA1 datasheet, TT240N36KOFHPSA1 pinout, TT240N36KOFHPSA1 application, or TT240N36KOFHPSA1 equivalent, key selection criteria include verified V_DRM/V_RRM = 3600 V, I_TAVM = 240 A, critical dv/dt rating of 1000 V/µs (6th letter F), gate trigger current ≤250 mA, and junction-to-case thermal resistance of 0.0373 °C/W per arm under DC conditions.

Technical Context

This thyristor module implements a two-arm, bidirectional phase-controlled switching topology optimized for B2 (two-pulse) and B6 (six-pulse) bridge configurations. Its pressure-contact Si pellet design with aluminum nitride (AlN) insulation enables high transient thermal impedance resilience and stable operation up to 125°C junction temperature.

It supports natural and forced cooling modes with validated thermal performance on KM17 heatsinks. The device requires precise gate triggering (V_GT ≤ 1.5 V, I_GT ≤ 250 mA) and exhibits low conduction loss (V_T ≤ 3.43 V at 1200 A, r_T = 1.7 mΩ) while maintaining high critical rate-of-rise immunity (dv/dt)_cr = 1000 V/µs and (di/dt)_cr = 100 A/µs.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum allowable case temperature (T_C) is 125°C, aligned with the 125°C maximum junction temperature (T_{vj max}) and thermal resistance R_thJC = 0.0373 °C/W. At I_TAVM = 240 A, case temperature must be maintained ≤85°C to ensure junction stays within limit under worst-case thermal conditions.

Does TT240N36KOFHPSA1 require forced cooling?

No-natural cooling is viable for reduced-load operation, but forced cooling (e.g., Papst 4650N fan on KM17 heatsink) is required to sustain full I_TAVM = 240 A. Thermal data shows T_C exceeds 125°C under natural convection at rated current, making forced airflow essential for continuous duty.

Can this module be used in anti-parallel configuration for AC output switching?

Yes-its dual-arm architecture supports anti-parallel connection (A1–K2 and A2–K1 cross-linked) to form a bidirectional AC switch. Gate timing must ensure strict non-overlap to prevent shoot-through; the 350 µs t_q and 1000 V/µs (dv/dt)_cr enable robust commutation in such topologies.

What gate drive voltage and current are required for reliable turn-on?

A minimum gate trigger voltage of 1.5 V and current of 250 mA (at v_D = 6 V, T_vj = 25°C) is required. Practical designs use 15–20 V pulses with ≥500 mA peak current and <2 µs rise time to ensure margin against temperature drift and parameter spread across production lots.
