Product details
Overview
T560N18TOFXPSA1 from Infineon Technologies is a high-power, phase-control thyristor designed for industrial AC power regulation in medium-voltage motor drives and static VAR compensators. It delivers 1800 V repetitive peak off-state voltage (VDRM/VRRM), 809 A RMS on-state current (ITRMSM), and 6900 A non-repetitive surge current (ITSM) at maximum junction temperature. Its pressure-contact silicon pellet construction enables robust operation in forced-air or liquid-cooled rectifier stacks.
For engineers reviewing the T560N18TOFXPSA1 datasheet, T560N18TOFXPSA1 pinout, T560N18TOFXPSA1 application, or T560N18TOFXPSA1 equivalent, key selection criteria include gate trigger current (≤200 mA), critical dv/dt rating (1000 V/µs), thermal resistance (0.042 °C/W junction-to-case, two-sided cooling), and commutated turn-off time (250 µs typical).
Technical Context
This thyristor operates as a line-commutated, gate-controlled switch in half- or full-wave AC phase control topologies. Its 125 °C maximum junction temperature, 0.6 mΩ slope resistance, and 0.8 V threshold voltage support stable conduction under high-current sinusoidal loads with conduction angles down to 30°.
The device features a dual-cathode structure (main cathode + auxiliary cathode) and flat-round gate terminals compatible with AMP 60598 standards. Its transient thermal impedance model (ZthJC) is defined by five RC network elements, enabling accurate loss and temperature simulation for DC and AC duty cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1800 V - Sustains 1800 V repetitive forward/reverse blocking in AC line applications up to 1 kV RMS systems. |
| ITRMSM | 809 A - Maximum RMS on-state current under specified thermal conditions; defines continuous power handling capability. |
| ITAVM @ TC=85°C | 559 A - Average on-state current limit at 85 °C case temperature; used for thermal derating in heatsink design. |
| (dvD/dt)cr | 1000 V/µs - Minimum required snubber dv/dt immunity to prevent false turn-on during voltage transients. |
| tq (typ) | 250 µs - Typical commutated turn-off time; determines minimum dead-time in forced-commutated inverters. |
| RthJC (two-sided) | 0.042 °C/W - Junction-to-case thermal resistance with two-sided cooling; sets baseline for heatsink sizing. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Main current terminal (positive conduction path) | High-current input node; requires low-inductance busbar connection and thermal interface to heatsink. |
| Cathode (2) | Main current terminal (negative conduction path) | Primary return path; electrically and thermally coupled to main heatsink surface. |
| Gate (4) | Control input for triggering conduction | Flat or round terminal per AMP 60598; accepts ≤200 mA trigger current with ≤2 V gate voltage. |

Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact Si pellet | Enables scalable current handling without wire bonds; supports >10 kN clamping force for low contact resistance and long-term thermal cycling reliability. |
| Dual-cathode architecture | Separates main power return from gate reference path, reducing gate loop inductance and improving di/dt immunity during turn-on. |
| 125 °C max junction temperature | Allows operation in high-ambient industrial environments (e.g., converter cabinets at 70 °C ambient) with margin for transient overloads. |
| 250 µs typical tq | Supports line-commutated switching up to 400 Hz in cycloconverters and static transfer switches with predictable commutation margins. |
| 1000 V/µs critical dv/dt | Reduces need for external snubbers in 50/60 Hz AC mains applications with moderate voltage transients (e.g., transformer inrush, capacitor switching). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT1600N18KOF | Higher ITAVM (625 A @ TC=85°C); lower RthJC (0.038 °C/W); same VDRM/VRRM and tq. | Better suited for space-constrained, high-efficiency rectifiers requiring <0.04 °C/W thermal resistance. | Select when thermal budget is tighter and clamping infrastructure supports higher mechanical load (12 kN). |
| T590N18TOF | Lower ITRMSM (720 A); identical VDRM/VRRM and gate characteristics; no auxiliary cathode terminal. | Targeted at cost-sensitive, single-cathode legacy systems where gate reference noise is not critical. | Choose for retrofit projects where footprint and gate drive compatibility are prioritized over peak RMS current. |
Compared with TT1600N18KOF and T590N18TOF, the T560N18TOFXPSA1 offers balanced trade-offs: sufficient RMS current for most industrial drives, auxiliary cathode for stable gate referencing, and proven field reliability in SVC deployments-making it optimal for new designs requiring verified performance at 1800 V and 800 A-class ratings.

FAQ
What is the recommended gate drive circuit for T560N18TOFXPSA1?
A pulse-transformer–based or optocoupler-isolated gate driver delivering ≥1 A peak trigger current for ≤20 µs is recommended. The gate must be driven with ≤2 V open-circuit voltage and ≤200 mA steady-state current. Use a 10 Ω series resistor and local 100 nF bypass capacitor at the gate terminal to suppress ringing and ensure reliable turn-on under high dv/dt conditions.
Can T560N18TOFXPSA1 be used in forced-commutated inverters?
No-it is a line-commutated thyristor without self-turn-off capability. It requires external commutation (e.g., LC snubber or auxiliary SCR) to interrupt current. Its 250 µs typical tq applies only to natural commutation in AC systems; it cannot be actively turned off by gate control.
What is the significance of the auxiliary cathode (terminal 5)?
The auxiliary cathode provides a dedicated, low-inductance reference point for the gate drive circuit, decoupling gate triggering from main cathode voltage transients. This improves turn-on consistency across the silicon area and reduces sensitivity to di/dt-induced false triggering in high-power stacks.
How does cooling configuration affect its rated current?
Rated ITAVM drops from 559 A (two-sided cooling) to 400 A (anode-only) and 350 A (cathode-only) at TC = 85 °C. Two-sided cooling halves the effective thermal resistance, allowing full RMS current utilization. Mounting must ensure uniform 5–10 kN clamping force across both ceramic interfaces to avoid hot spots.
