Product details
Overview
TT160N16SOFHPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial drive systems. It features 1600 V repetitive peak off-state voltage (VDRM/VRRM), 160 A average on-state current at TC = 85 °C, 5200 A non-repetitive surge current (ITSM), and electrically insulated Al₂O₃ baseplate. It is used in soft starters for three-phase induction motors.
For engineers reviewing the TT160N16SOFHPSA1 datasheet, TT160N16SOFHPSA1 pinout, TT160N16SOFHPSA1 application, or TT160N16SOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.145 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (≤145 mA), and isolation test voltage (3.6 kV for 1 sec).
Technical Context
This dual-thyristor module operates in phase-controlled AC power regulation, where conduction angle is modulated via gate triggering to control RMS output voltage. Its 125 °C maximum junction temperature and 0.99 mΩ slope resistance enable stable operation under high-current, low-duty-cycle transients typical in motor soft-start sequences.
The module uses solder-bond interconnection technology and industrial-standard package with electrically isolated ceramic baseplate. Its 10 mm creepage distance and 3.6 kV isolation support use in grounded-neutral industrial mains (400–690 VAC) with reinforced insulation requirements per IEC 61140 Class 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1600 V - Withstands repetitive 1600 V reverse or forward blocking voltage during AC half-cycles without conduction. |
| ITAVM (TC = 85 °C) | 160 A - Maximum continuous average on-state current per arm at heatsink temperature of 85 °C. |
| ITSM (10 ms) | 5200 A - Peak non-repetitive surge current capability for short-circuit or motor lock-rotor protection. |
| RthJC | 0.145 K/W - Thermal resistance from junction to case per arm, defining minimum heatsink requirement for thermal design. |
| (dvD/dt)cr | 1000 V/µs - Minimum rate of rise of off-state voltage before false triggering, enabling robust noise immunity in EMI-prone drive cabinets. |
| VISOL (1 sec) | 3.6 kV RMS - Reinforced insulation withstand voltage between terminals and baseplate, meeting IEC 61140 safety standards. |
| Weight | 165 g - Mechanical mass consistent with compact industrial module footprint and mounting torque specification (5 Nm). |

IC Role / Device Role / Timing Role: Bidirectional power switch implementing zero-crossing or phase-shifted firing to adjust effective power delivered to load. Use Value: 1000 V/µs (dv/dt)cr rating prevents spurious turn-on from voltage transients induced by SCR-based heater banks sharing same bus. | Use Scenario: Contactless replacement of mechanical tap changers in distribution transformers to avoid arcing and maintenance downtime. IC Role / Device Role / Timing Role: High-voltage static switch performing make-before-break transitions between transformer taps under load.

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TD160N16SOF | Same VDRM/VRRM (1600 V), identical ITAVM (160 A), but lower ITSM (4500 A vs. 5200 A); RthJC = 0.165 K/W (per arm, DC). | Reduced surge margin limits suitability for motor starting with high inertia loads or frequent restarts. | Select when thermal budget allows higher RthJC and surge events are infrequent or externally clamped. |
| TT175N16SOF | Higher ITAVM (175 A at TC = 85 °C), same VDRM/VRRM, ITSM = 5600 A, RthJC = 0.135 K/W (per arm, DC). | Enables higher continuous power density in space-constrained UPS or heating controllers. | Choose for new designs targeting >10% power headroom or extended lifetime under thermal cycling. |
Compared with TD160N16SOF and TT175N16SOF, TT160N16SOFHPSA1 offers optimal balance of surge capability (5200 A), thermal resistance (0.145 K/W), and gate sensitivity (≤145 mA IGT), making it preferred for soft starters where transient overload and precise low-current triggering are jointly critical.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum allowable case temperature (TC) is +125 °C, but the rated average on-state current ITAVM = 160 A is specified at TC = 85 °C. Derating curves in the datasheet show linear reduction to ~110 A at TC = 125 °C for Θ = 180° conduction, based on thermal impedance modeling and junction temperature limit of 125 °C.
Does TT160N16SOFHPSA1 require external snubber circuits?
Snubbers are recommended for applications exceeding 1000 V/µs dv/dt or involving inductive loads with rapid current interruption. While the device has a rated (dv/dt)cr of 1000 V/µs, real-world line transients in industrial environments often exceed this; RC snubbers across A–K terminals improve reliability in soft starters and static switches.
How is gate drive isolation implemented in this module?
Gate terminals G1 and G2 are electrically isolated from the main terminals (A1/K1/A2/K2) and baseplate. Isolation is achieved via internal creepage/clearance design and reinforced insulation (3.6 kV/1 sec). External gate drivers must provide ≥3.6 kV isolation and comply with IEC 61800-5-1 for functional safety in drive applications.
Can TT160N16SOFHPSA1 be used in parallel configurations?
Parallel operation is not recommended due to mismatch in dynamic parameters (e.g., tq, vT) and thermal coupling limitations. The module is designed for single-arm or dual-arm bridge use. For higher current, Infineon specifies multi-module layouts with individual heatsinking and matched gate drive timing-never direct paralleling of A/K terminals without active current balancing.
