Product details
Overview
T1700N16H75VTXPSA1 from Infineon Technologies is a phase-control thyristor designed for high-power AC line commutation in industrial medium-voltage converters and soft starters. It delivers 1770 A average on-state current at 85 °C case temperature, 1600 V repetitive peak off-state voltage, and withstands 34 kA non-repetitive surge current - enabling robust rectification in drive systems operating up to 135 °C junction temperature.
For engineers reviewing the T1700N16H75VTXPSA1 datasheet, T1700N16H75VTXPSA1 pinout, T1700N16H75VTXPSA1 application, or T1700N16H75VTXPSA1 equivalent, key selection criteria include clamping force range (14–26 kN), two-sided thermal resistance (17.0 K/kW), gate trigger current ≤250 mA, and critical dv/dt rating of 1000 V/µs under full blocking conditions.
Technical Context
This thyristor operates as a line-commutated, gate-controlled power switch in half- or full-wave AC phase control topologies. Its design supports sinusoidal conduction angles up to 180° and rectangular waveforms down to 30°, with validated turn-off time of 230 µs under 100 V reverse voltage and 20 V/µs dv/dt stress.
It features a pressure-contact silicon pellet housed in an industry-standard disc-type package with auxiliary cathode terminal. Thermal performance is defined by analytical ZthJC transient impedance models for anode-, cathode-, and two-sided cooling configurations - critical for accurate loss and temperature prediction in high-duty-cycle drives.

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT1700N16KOF | Same VDRM (1600 V), higher ITAVM (1850 A @ TC=85°C), lower RthJC (16.0 K/kW), no auxiliary cathode terminal | Lacks auxiliary cathode - limits snubber layout flexibility in high-di/dt cycloconverter outputs | Select when maximum thermal efficiency is prioritized and gate drive return path can be routed through main cathode |
| ST1700N16H75 | Identical VDRM, ITAVM, and RthJC; differs in clamping force spec (12–24 kN vs. 14–26 kN) and gate pin geometry (round vs. flat) | Round gate pin requires different socket or clamp interface; slightly reduced mechanical margin for high-vibration environments | Choose for legacy ST-compatible tooling where flat-to-round adapter is unavailable |
Compared with TT1700N16KOF and ST1700N16H75, T1700N16H75VTXPSA1 offers superior gate drive isolation via auxiliary cathode and broader clamping force tolerance - critical for field-replaceable assemblies subject to repeated thermal cycling and mechanical wear.

FAQ
What is the maximum allowable clamping force for T1700N16H75VTXPSA1?
The specified clamping force range is 14–26 kN. Exceeding 26 kN risks mechanical damage to the pressure-contact silicon pellet or deformation of the copper housing, while forces below 14 kN increase contact resistance and thermal impedance beyond rated RthJC. Mounting must use calibrated torque tools and flat, parallel heatsink surfaces per Infineon Application Note AN2019-07.
Does T1700N16H75VTXPSA1 support forced commutation?
No - it is a line-commutated thyristor only. Turn-off relies on natural current zero-crossing in AC supply; it lacks integrated turn-off circuitry or gate-turn-off (GTO) capability. Forced commutation requires external LC snubbers or auxiliary inverters, and its 230 µs tq value defines the minimum safe commutation interval under specified test conditions (vRM = 100 V, dvD/dt = 20 V/µs).
Can this thyristor be used in DC applications?
Yes, but only in DC-switching roles where external circuitry ensures current interruption - such as crowbar protection or DC breaker stages. Its DC blocking rating (VDRM = 1600 V) and 1770 A ITAVM at TC = 85 °C are valid for steady-state DC, but it cannot self-commutate; sustained DC conduction without forced current zeroing will cause thermal runaway.
What gate drive voltage and current are required for reliable triggering?
A minimum gate trigger voltage of 2 V and current of 250 mA (at 25 °C, vD = 12 V) ensures turn-on under worst-case conditions. Gate pulse width must exceed 20 µs to guarantee latching, and peak gate power must stay within PGM = 60 W for 0.5 ms pulses. The flat-pin gate terminal is rated for 2.8 × 0.5 mm cross-section and requires low-inductance PCB routing to avoid false triggering from di/dt coupling.
