Product details
Overview
T570N65TOFXPSA1 from Infineon Technologies is a phase-control thyristor designed for medium-voltage power conversion and soft-start applications. It delivers 540 A average on-state current at 85°C case temperature, 6500 V repetitive peak off-state voltage, and withstands 10.5 kA surge current (10 ms). Its ceramic-encapsulated, pressure-contact construction enables operation in high-reliability industrial rectifier and drive systems.
For engineers reviewing the T570N65TOFXPSA1 datasheet, T570N65TOFXPSA1 pinout, T570N65TOFXPSA1 application, or T570N65TOFXPSA1 equivalent, key selection criteria include verified di/dt capability (150 A/µs), dv/dt rating (1000 V/µs), thermal resistance (21 K/kW junction-to-case, two-sided cooling), and gate trigger parameters (IGT ≤ 350 mA, VGT ≤ 2.5 V).
Technical Context
This thyristor operates as a line-commutated, gate-controlled power switch in AC phase-angle control topologies. Its 125°C maximum junction temperature, 1000 µs typical turn-off time (tq), and 6.2 mAs recovered charge (Qr) define its commutation behavior under high-voltage, high-current conditions.
The device uses a silicon pellet with double-sided pressure contact and hermetically sealed ceramic housing. Its gate-cathode terminals follow DIN 46244 mechanical standards, and clamping force must be maintained between 13–23 kN to ensure stable thermal and electrical performance across -40°C to +125°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 6500 V - blocks 50/60 Hz AC line voltages up to medium-voltage distribution levels (e.g., 6.6 kV systems) |
| ITAVM (TC = 85°C) | 540 A - continuous DC or RMS current handling capacity under forced-air or liquid-cooled heatsink conditions |
| ITSM (10 ms) | 10500 A - short-circuit robustness during fault clearing without latch-up or thermal runaway |
| (diT/dt)cr | 150 A/µs - ensures reliable turn-on even with steep current transients in high-inductance drive circuits |
| (dvD/dt)cr | 1000 V/µs - prevents false triggering during rapid voltage transients in converter snubber networks |
| RthJC (two-sided) | 21 K/kW - thermal path efficiency enabling 85°C case temperature with ≤25.7 kW conduction loss dissipation |
| VTO / rT | 1.35 V / 1.4 mΩ - low conduction loss profile supporting high-efficiency rectification at rated current |
Pinout & Package
Hermetically sealed ceramic package with double-sided cooling interface, 76 mm max diameter, 26 mm height, and 50 mm contact diameter. Designed for bolt-down mounting with controlled clamping force (13–23 kN).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Main current terminal (high-side) | Carries full load current into device; requires low-inductance busbar connection and thermal interface to heatsink |
| Cathode (2) | Main current terminal (low-side) | Completes main conduction path; symmetric thermal design allows bidirectional heatsinking |
| Gate (4) | Control input | DIN 46244-compliant 2.8×0.5 mm flat contact; accepts ≤350 mA trigger current at ≤2.5 V |
| Kathode (4) | Reference return for gate drive | Shared cathode reference ensures low-noise gate triggering; must be routed with minimal loop area |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic ceramic housing | Enables operation in humid, dusty, or corrosive industrial environments without potting or conformal coating |
| High di/dt turn-on capability | 150 A/µs rating supports direct switching into highly inductive motor windings without snubber assistance |
| Two-sided thermal interface | 21 K/kW RthJC enables balanced heat extraction from both anode and cathode surfaces for compact thermal design |
| Pressure-contact silicon pellet | Eliminates wire bonds and solder interfaces, improving long-term reliability under thermal cycling stress |
| 125°C maximum junction temperature | Extends usable lifetime in high-ambient-temperature enclosures such as MV drive cabinets and traction converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT570N65KOF | Same voltage/current ratings but TO-247-3L package; lower surge rating (9.5 kA vs. 10.5 kA); no pressure-contact construction | Not suitable for >500 A RMS or high-di/dt industrial drives requiring ceramic hermeticity | Select only for PCB-mount prototyping or low-power auxiliary controls where thermal cycling stress is minimal |
| T570N65TOF | Identical core specs but lacks XPSA1 suffix indicating extended production traceability and enhanced gate parameter screening | No difference in functional performance; differs only in manufacturing lot control and test documentation depth | Prefer T570N65TOFXPSA1 for OEM production requiring full DMX code traceability and I²t consistency validation |
Compared with TT570N65KOF and T570N65TOF, the T570N65TOFXPSA1 provides superior surge robustness, hermetic reliability, and production traceability-critical for medium-voltage infrastructure where field failure consequences are severe and replacement logistics are constrained.

FAQ
What is the required gate drive voltage and current for reliable turn-on?
The T570N65TOFXPSA1 requires ≤2.5 V gate trigger voltage and ≤350 mA gate trigger current at 25°C with 12 V anode-cathode voltage. Gate pulse width must exceed 20 µs, and diG/dt ≥6 A/µs ensures consistent latching. Exceeding 40 W peak gate power (1 ms pulse) risks gate metallization damage.
How should the clamping force be applied during mounting?
Clamping force must be uniformly applied between 13 kN and 23 kN using calibrated torque tools and hardened steel washers. Under-torque increases contact resistance and thermal impedance; over-torque risks ceramic fracture or silicon pellet deformation. Force verification per DIN EN 60747-6 is mandatory before energization.
Can this thyristor be used in asymmetrical half-controlled bridges?
Yes-it supports asymmetrical configurations where only one leg is thyristor-controlled and the other uses diodes. Its 6500 V VDRM/VRRM and 1000 V/µs dv/dt rating maintain safe blocking during reverse recovery of freewheeling diodes, provided snubber networks limit voltage overshoot to <80% VRRM.
What is the maximum allowable case temperature for continuous operation?
The maximum continuous case temperature is 85°C for rated ITAVM = 540 A. At 70°C case, ITAVM rises to 660 A; at 55°C, it reaches 760 A. Operation above 85°C case requires derating per the thermal transient impedance curve (ZthJC) and must not exceed 125°C junction temperature under any condition.
