Infineon Technologies TD160N16SOFHPSA1

Overview

TD160N16SOFHPSA1 from Infineon Technologies is a phase-control thyristor module with dual anti-parallel thyristor configuration in an industrial-standard insulated package, rated for 1600 V repetitive peak off-state voltage (VDRM/VRRM), 160 A average on-state current at TC = 85 °C (ITAVM), and 5200 A non-repetitive surge current (ITSM). It serves as a high-power AC line commutated switching element in soft starters and static power controllers.

For engineers reviewing the TD160N16SOFHPSA1 datasheet, TD160N16SOFHPSA1 pinout, TD160N16SOFHPSA1 application, or TD160N16SOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.145 K/W), gate trigger current (≤145 mA), critical dv/dt rating (1000 V/µs), and electrically insulated baseplate for safe mounting on heatsinks without additional isolation.

Technical Context

This dual-thyristor module implements line-commutated AC power control using two inverse-parallel silicon-controlled rectifiers (SCRs) in a single package. It supports full-wave phase-angle control with gate-triggered turn-on and natural commutation at current zero-crossing.

Designed for forced-air or liquid-cooled industrial drives, it delivers 275 A RMS on-state current (ITRMSM) and withstands 1700 V non-repetitive reverse surge (VRSM). Its 0.99 mΩ slope resistance (rT) and 1.1 V threshold voltage (VT0) define conduction loss behavior under high-current DC or low-conduction-angle AC operation.

Key Specifications

FAQ

What is the maximum allowable case temperature for continuous operation?

The maximum case temperature (TC) for continuous operation is defined by the ITAVM derating curve: at TC = 85 °C, the module supports 160 A average on-state current per arm. Operation above 85 °C requires linear derating to zero at TC = 125 °C, per the thermal data on page 7 of the technical information document.

Does TD160N16SOFHPSA1 require external snubber circuits?

Snubbers are not mandatory due to its 1000 V/µs critical dv/dt rating, but may be needed in high-di/dt applications like motor drives with long cable runs. The module's 320 µs typical turn-off time (tq) and 100 A/µs critical di/dt rating support snubberless operation in most industrial phase-control topologies.

How is gate drive isolation implemented in this module?

Gate terminals G1 and G2 are electrically isolated from the main current terminals and baseplate. The module does not integrate gate drivers; external optocoupled or pulse-transformer-based gate drivers must provide ≥3.6 kV reinforced isolation between control circuitry and power stage, matching the baseplate's insulation rating.

Can TD160N16SOFHPSA1 be used in single-phase versus three-phase configurations?

Yes-it supports both. In single-phase, it functions as a full-wave AC switch (e.g., in soft starters). In three-phase, two modules configure a six-pulse bridge (B6), as shown in Figure 8 of the technical document, delivering up to 500 A output with RthCA = 0.15 K/W heatsink thermal resistance.
