Infineon Technologies TT60N16SOFHPSA1

Overview

TT60N16SOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line commutated switching in industrial power conversion systems. It features 1600 V repetitive peak off-state voltage (VDRM/VRRM), 55 A average on-state current at TC = 85 °C, 1500 A non-repetitive surge current (10 ms), and electrically insulated baseplate construction for safe mounting on heatsinks. It is used in soft starters for three-phase motors.

For engineers reviewing the TT60N16SOFHPSA1 datasheet, TT60N16SOFHPSA1 pinout, TT60N16SOFHPSA1 application, or TT60N16SOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.47 K/W), gate trigger current (≤100 mA), critical dv/dt rating (1000 V/µs), and isolation test voltage (3.6 kV for 1 sec).

Technical Context

This dual-thyristor module operates in line-commutated mode with symmetrical forward/reverse blocking capability and is rated for 130 °C maximum junction temperature. Its gate-controlled turn-on behavior requires precise triggering pulses with minimum 1 A peak gate current and ≤1 µs delay time under standard test conditions.

The module uses solder-solder interconnection technology and an industrial-standard package with Al₂O₃-based electrical insulation between the baseplate and semiconductor die. Thermal performance is characterized by transient junction-to-case impedance (ZthJC) curves and DC thermal resistance values differentiated per arm and per module configurations.

Key Specifications

Pinout & Package

TT60N16SOFHPSA1 is housed in an industrial-standard isolated baseplate module with solder-solder termination. The package includes two thyristor arms sharing a common electrically insulated copper baseplate (20 mm thick), with terminals labeled T1/T2 (main anode/cathode per arm) and G1/G2 (independent gate connections). Mechanical mounting uses M1 screws (5 Nm torque) and electrical connections use M2 terminals (3 Nm torque).

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum case temperature (TC) for continuous operation is +125 °C, as specified in the mechanical properties section. However, the rated average on-state current (ITAVM = 55 A) is defined at TC = 85 °C. Operation above 85 °C requires linear derating per the TC vs. ITAVM curve on page 7 of the datasheet, down to zero current at 125 °C.

Does TT60N16SOFHPSA1 require a heatsink, and what thermal interface material is recommended?

Yes, a heatsink is mandatory due to its 0.47 K/W junction-to-case thermal resistance. Infineon specifies a maximum RthCH (case-to-heatsink) of 0.11 K/W per module. Use thermally conductive grease or silicone-based pads with ≤0.1 mm bond line thickness and ≥1.5 W/m·K thermal conductivity, applied uniformly to the 20 mm insulated baseplate surface before mounting with 5 Nm torque.

Can this module be used in a single-phase full-wave rectifier configuration?

Yes-TT60N16SOFHPSA1 contains two independent thyristor arms and can be wired as a single-phase full-wave (B2) bridge rectifier. Terminals T1/T2 form one arm and T3/T4 the second; gates G1/G2 are triggered 180° out-of-phase. This configuration supports up to 55 A average DC output with natural commutation at 50/60 Hz.

What is the gate drive power requirement for reliable turn-on?

Reliable turn-on requires a gate pulse with peak current ≥1 A, duration ≥20 µs, and peak voltage ≤2.5 V. The maximum rated peak gate power is 60 W for 0.5 ms (curve "c" on page 6). Gate resistor selection must limit IGT to ≤100 mA while delivering sufficient di/dt to exceed the 140 A/µs critical rate, typically using 10–22 Ω series resistance with isolated pulse transformers or optocouplers.
