Infineon Technologies TT500N16KOFXPSA1

Overview

TT500N16KOFXPSA1 from Infineon Technologies is a pressure-contact thyristor module designed for phase-controlled AC power regulation in industrial power converters. It delivers 500 A average on-state current at 85°C case temperature, supports 1600 V repetitive peak off-state voltage (VDRM/VRRM), and features 0.85 V threshold voltage and 0.35 mΩ slope resistance - enabling high-efficiency soft starters and static switches in motor drive rectifiers.

For engineers reviewing the TT500N16KOFXPSA1 datasheet, TT500N16KOFXPSA1 pinout, TT500N16KOFXPSA1 application, or TT500N16KOFXPSA1 equivalent, key selection criteria include verified surge current rating (17 kA @ 10 ms), junction-to-case thermal resistance (0.055 K/W), gate trigger parameters (IGT ≤ 250 mA, VGT ≤ 2.2 V), and electrically insulated base plate compliance with IEC61140 Class 1 insulation.

Technical Context

This double-sided, dual-arm thyristor module uses pressure-contact silicon pellet technology to eliminate wire bonds and enhance thermal cycling reliability. Its 180° conduction-angle capability supports full-wave phase control in B2 (two-pulse) and B6 (six-pulse) bridge configurations, with validated turn-off time (tq = 250 µs typ.) under commutated conditions (vRM = 100 V, dvD/dt = 20 V/µs).

The module integrates two independent thyristor arms in an industrial-standard 60 mm package with AlN-based internal insulation. Gate triggering is optimized for low diG/dt sensitivity (critical diT/dt = 200 A/µs) and high dvD/dt immunity (critical dvD/dt = 1000 V/µs), ensuring robust operation in noisy drive environments.

FAQ

What is the maximum allowable case temperature for continuous operation?

The TT500N16KOFXPSA1 is rated for continuous operation up to TC = 85°C, with derated ITAVM down to zero at TC = 125°C. The datasheet provides explicit ITAVM vs. TC curves for conduction angles from 30° to 180°, confirming 500 A at 85°C for full-wave (180°) operation.

Does this module require forced air or liquid cooling?

No - the module is designed for conduction-cooled mounting onto a heatsink with thermal interface material (TIM). With RthCH (case-to-heatsink) ≤ 0.0075 K/W using TIM, and RthCA (heatsink-to-ambient) ≤ 0.25 K/W, natural convection cooling suffices for ≤450 W total dissipation per arm at 40°C ambient.

Can TT500N16KOFXPSA1 be used in anti-parallel configuration for AC switching?

Yes - its dual-arm architecture supports anti-parallel connection by cross-wiring A1–K2 and K1–A2 to form a bidirectional AC switch. Gate drive must be synchronized with zero-crossing detection and respect tq = 250 µs minimum off-time to ensure commutation before next half-cycle.

What is the creepage distance and insulation class of the base plate?

The module features 19 mm creepage distance across the insulated base plate and complies with Basic Insulation (Class 1 per EN 61140 / IEC 61140), validated by 3.6 kV RMS insulation test voltage for 1 second. This permits direct mounting on grounded metal heatsinks without supplemental isolation.
