Product details
Overview
T560N12TOFXPSA1 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 1260 A RMS on-state current, 1200 V repetitive peak off-state voltage (VDRM/VRRM), and 8000 A non-repetitive surge current (ITSM) at 10 ms, operating up to 125 °C junction temperature in two-sided cooled configurations.
For engineers reviewing the T560N12TOFXPSA1 datasheet, T560N12TOFXPSA1 pinout, T560N12TOFXPSA1 application, or T560N12TOFXPSA1 equivalent, key selection criteria include gate trigger current (≤200 mA), critical dv/dt rating (1000 V/µs), thermal resistance (0.044 °C/W j-c, two-sided), and latching/holding current behavior under 50 Hz line conditions.
Technical Context
This thyristor employs a planar silicon die with pressure-contact construction, enabling robust commutation in phase-angle controlled AC systems. Its 1200 V VDRM rating supports operation on 690 V AC three-phase lines with margin, while the 250 µs typical turn-off time (tq) ensures reliable forced commutation in line-commutated inverters and cycloconverters.
The device features a defined on-state characteristic (vT = 0.8 V + 0.6 mΩ·iT) and strict gate control parameters: max 2 V gate trigger voltage (VGT), 300 mA holding current (IH), and 1200 mA latching current (IL) - all specified at 25 °C with 12 V anode-cathode voltage and standardized diG/dt.
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 |
|---|---|---|---|
| TT1200N12KOF | Same VDRM (1200 V) and ITAVM (559 A), but TO-200AB package with single-sided cooling (RthJC = 0.067 °C/W) | Requires larger heatsink surface area; unsuitable for space-constrained dual-cooled designs | Select when mechanical integration favors stud-mount with single heatsink interface |
| T560N14TOFXPSA1 | Higher VDRM/VRRM (1400 V); identical package, thermal, and gate specs | Enables use on 11 kV distribution networks; increases voltage margin but adds cost and gate drive energy | Select only if system overvoltage transients exceed 1200 V or standards require ≥1400 V rating |
Compared with TT1200N12KOF, T560N12TOFXPSA1 offers 33% lower thermal resistance for higher power density; compared with T560N14TOFXPSA1, it provides optimal cost-performance balance for 690 V AC systems without over-specifying voltage rating.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (TC) is not fixed but depends on average on-state current (ITAV) and conduction angle. At 180° sinusoidal conduction with two-sided cooling, TC must not exceed 85 °C when ITAV = 559 A, per the derating curve on page 6 of the datasheet. For lower currents or shorter conduction angles, TC may reach 125 °C.
Is a heatsink required, and what clamping force is needed?
Yes - mandatory two-sided heatsinking is required due to its press-pack construction. The datasheet specifies a clamping force of 5–10 kN applied uniformly across the anode and cathode surfaces to maintain thermal and electrical contact integrity and achieve the rated RthJC of 0.044 °C/W.
Can this thyristor be used in parallel configurations?
No - the T560N12TOFXPSA1 is not characterized or recommended for paralleling. Its on-state voltage spread (vT = 0.8 V to 1.92 V at 1600 A) and thermal coupling limitations make current sharing unreliable without active balancing, which is not supported by its gate drive or thermal design.
What gate drive circuit meets the latching and holding current requirements?
A gate pulse with ≥1 A peak current, ≥20 µs duration, and diG/dt ≥1 A/µs satisfies latching (IL ≤1200 mA) and holding (IH ≤300 mA) requirements per DIN IEC 60747-6. Standard pulse transformers (e.g., IXYS GPT-100) or opto-triac drivers with 2 W peak output meet these specs without external amplification.
