Infineon Technologies TT210N16KOFHPSA1

Overview

TT210N16KOFHPSA1 from Infineon Technologies is a phase-control thyristor module with dual 1600 V VDRM/VRRM rating, 210 A average on-state current (TC = 85 °C), and pressure-contact construction for high-reliability power switching in industrial AC line control. It integrates two inverse-parallel thyristor arms in an electrically insulated industrial-standard package, used in soft starters, static switches, and UPS rectifiers.

For engineers reviewing the TT210N16KOFHPSA1 datasheet, TT210N16KOFHPSA1 pinout, TT210N16KOFHPSA1 application, or TT210N16KOFHPSA1 equivalent, key selection criteria include repetitive peak voltage (1600 V), surge current capability (6600 A), junction-to-case thermal resistance (0.124 K/W), gate trigger parameters (IGT ≤ 200 mA, VGT ≤ 2 V), and pressure-contact reliability for high-cycle industrial operation.

Technical Context

This thyristor module implements a dual-arm, inverse-parallel configuration enabling bidirectional AC conduction without external anti-parallel diodes. Each arm supports 1600 V blocking and delivers 210 A average current at TC = 85 °C, with critical dv/dt rating of 1000 V/µs and di/dt capability of 150 A/µs under specified gate drive conditions.

Thermal performance is defined by a maximum junction temperature of 125 °C and a transient thermal impedance ZthJC profile optimized for sinusoidal and rectangular conduction angles (Θ = 30°–180°). The electrically insulated base plate (AlN ceramic) enables direct mounting to heatsinks without additional isolation hardware.

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum case temperature for continuous operation is 85 °C, at which the device delivers its rated 210 A average on-state current per arm. Operation above this temperature requires derating per the ITAVM vs. TC curve in the datasheet, with absolute maximum junction temperature limited to 125 °C.

Does TT210N16KOFHPSA1 require external snubber circuits?

Snubbers are recommended for inductive loads due to its 1000 V/µs critical dv/dt rating. While the module can operate without snubbers in resistive or lightly inductive applications, RC snubbers are advised to suppress voltage overshoot during commutation and ensure reliable turn-off in motor drive and UPS rectifier topologies.

How is gate drive isolation implemented for this module?

Gate terminals G1/K1 and G2/K2 are referenced to their respective cathodes (K1 and K2), not to the base plate. Isolation must be provided between gate drivers and main power circuitry-typically using pulse transformers or optocouplers rated for ≥3.6 kV RMS to match the module's insulation test voltage.

Can TT210N16KOFHPSA1 be paralleled with identical units for higher current capacity?

No-this module is not designed for parallel operation. Its pressure-contact construction and thermal coupling to a shared base plate make current sharing unpredictable. For higher current, select a higher-rated module (e.g., TT330N series) or use multi-module systems with independent thermal management and forced current balancing.
