Product details
Overview
T560N16TOFXPSA1 from Infineon Technologies is a phase-control thyristor designed for high-power AC line commutation in industrial rectifiers, motor drives, and static VAR compensators. It delivers 1600 V repetitive peak off-state voltage (VDRM/VRRM), 809 A RMS on-state current (ITRMSM), and 559 A average on-state current at 85°C case temperature, operating reliably in forced-air or liquid-cooled 3-phase bridge configurations.
For engineers reviewing the T560N16TOFXPSA1 datasheet, T560N16TOFXPSA1 pinout, T560N16TOFXPSA1 application, or T560N16TOFXPSA1 equivalent, key selection criteria include its 120 A/µs critical di/dt rating, 1000 V/µs critical dv/dt capability, two-sided clamping thermal interface, and gate-trigger compatibility with standard pulse transformers or opto-triac drivers in medium-voltage SCR-based power converters.
Technical Context
This thyristor employs a planar silicon die with pressure-contact construction and dual-side heat sinking to sustain high-current conduction angles (up to 180°) under continuous sinusoidal or rectangular waveforms. Its gate-controlled turn-on behavior follows DIN IEC 60747-6 standards, with maximum 4 µs gate delay time and 1200 mA latching current ensuring robust triggering even under elevated junction temperatures.
The device features a defined on-state characteristic (vT = A + B·iT + C·ln(iT) + D·iT²) with slope resistance of 0.6 mΩ and threshold voltage of 0.8 V at 125°C, enabling accurate conduction loss modeling across 100–2800 A load ranges. Its transient thermal impedance (ZthJC) is analytically characterized for anode-, cathode-, and two-sided cooling modes, supporting precise thermal design in high-reliability industrial systems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT560N16KOF | Same VDRM/VRRM (1600 V) and ITAVM (559 A), but uses ceramic housing and single-side cooling (RthJC = 0.067 °C/W). | Lower thermal performance limits use in high-duty-cycle applications without auxiliary heatsinking. | Select when space constraints prohibit two-sided mounting or when lower-cost packaging suffices for intermittent loads. |
| T560N16TOF | Identical electrical specs but lacks auxiliary cathode terminal and has higher gate trigger current (IGT ≤ 250 mA). | Reduced triggering reliability in noisy EMI environments or long gate cable runs. | Select only for cost-sensitive legacy designs where auxiliary cathode is unused and gate drive margin is ample. |
Compared with TT560N16KOF and T560N16TOF, T560N16TOFXPSA1 offers superior thermal management via two-sided cooling and enhanced noise immunity through its auxiliary cathode, making it optimal for high-reliability, continuously rated industrial power conversion where thermal stability and gate robustness are critical.

FAQ
What is the maximum clamping force required for reliable thermal contact?
The T560N16TOFXPSA1 requires a mechanical clamping force between 5 kN and 10 kN across its copper baseplate to ensure low thermal resistance and uniform current distribution through the pressure-contact silicon die. Exceeding 10 kN risks die fracture, while forces below 5 kN increase RthJC and risk localized overheating under full-load operation.
Can this thyristor be used in forced-commutated circuits?
No - T560N16TOFXPSA1 is a line-commutated (natural-commutation) thyristor with no gate-turn-off capability. Its 250 µs typical turn-off time (tq) and lack of reverse gate control make it unsuitable for chopper or inverter topologies requiring active commutation; it is strictly intended for phase-controlled rectifiers and AC controllers where current naturally crosses zero.
What gate drive voltage and current are needed for reliable triggering?
A minimum gate trigger current of 200 mA and voltage of 2 V must be delivered within a 20 µs pulse width to guarantee turn-on at 125°C junction temperature. Recommended gate drive uses a pulse transformer or optocoupler delivering ≥1 A peak current for margin, with di/dt ≥1 A/µs to meet the 1200 mA latching current requirement under worst-case conditions.
Is auxiliary cathode connection mandatory in all applications?
The auxiliary cathode (Kaux) is not mandatory but strongly recommended for applications with high di/dt transients (>50 A/µs) or long gate loop inductance. It provides a dedicated low-inductance return path for gate current, reducing susceptibility to false triggering and improving consistency of firing angle control in multi-thyristor stacks.
