Infineon Technologies TD240N36KOFHPSA1

Overview

TD240N36KOFHPSA1 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-arm construction with AlN isolation, 0.039 °C/W junction-to-case thermal resistance per module, and is designed for industrial AC power control in medium-voltage rectifier and motor drive systems.

For engineers reviewing the TD240N36KOFHPSA1 datasheet, TD240N36KOFHPSA1 pinout, TD240N36KOFHPSA1 application, or TD240N36KOFHPSA1 equivalent, key selection criteria include verified V_DRM/V_RRM = 3600 V, I_TAVM = 240 A @ 85°C, critical (dv/dt)_cr = 1000 V/µs, gate trigger current ≤250 mA, and pressure-contact Si pellet packaging with M1 mechanical mounting torque specification.

Technical Context

This dual-thyristor module implements a B6 six-pulse bridge configuration with symmetrical arm layout and isolated gate terminals. Its design supports line-commutated operation up to 50/60 Hz, with validated turn-off time (t_q) of 350 µs at full-rated current and 100 V reverse recovery voltage.

Thermal performance is defined by transient junction-to-case impedance Z_thJC, with analytical R–τ elements enabling precise loss calculation under sinusoidal and rectangular conduction angles (Θ = 30°–180°). The module uses AlN ceramic for internal isolation and requires forced-air or natural cooling per specified heatsink types KM17/KM17-Papst 4650N.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum case temperature (T_C) is not fixed but depends on load current and conduction angle. At I_TAVM = 240 A and Θ = 180° sinusoidal conduction, T_C must not exceed 85°C with natural cooling on KM17 heatsink. Forced cooling extends allowable T_C up to 125°C only if junction temperature remains ≤125°C per thermal modeling using provided Z_thJC data.

Can TD240N36KOFHPSA1 be used in asymmetrical half-controlled rectifiers?

Yes-it supports asymmetrical configurations such as B2 two-pulse bridges. Each arm operates independently, allowing use of only one thyristor per AC phase leg with diode续流. The datasheet provides separate I_D vs. R_thCA curves for B2 operation, confirming 1000 A output at 25°C ambient with R_thCA = 0.015 °C/W.

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 T_vj = 25°C is required. For robust operation across temperature, gate pulses should deliver ≥300 mA peak into ≤10 Ω source impedance, with pulse width ≥20 µs and di/dt ≥1 A/µs to ensure latching at full junction temperature.

Is creepage distance sufficient for 3.6 kV isolation in polluted environments?

Yes-the module provides 19 mm creepage distance between main terminals and meets IEC 60664-1 requirements for Pollution Degree 3. When mounted per datasheet mechanical instructions (including specified torque and clean mounting surface), it achieves full 3.6 kV RMS insulation test rating at 50 Hz for 1 second, validated per EN 60747-5-1.
