Product details
Overview
T880N18TOFXPSA1 from Infineon Technologies is a phase-control thyristor designed for high-power AC line commutated switching in industrial rectifiers, motor drives, and static VAR compensators. It delivers 880 A average on-state current at TC = 85 °C, 1800 V repetitive peak off-state voltage (VDRM/VRRM), and 17.5 kA non-repetitive surge current (ITSM) with 200 A/µs critical di/dt rating.
For engineers reviewing the T880N18TOFXPSA1 datasheet, T880N18TOFXPSA1 pinout, T880N18TOFXPSA1 application, or T880N18TOFXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.032 °C/W two-sided), gate trigger current (≤250 mA), holding current (≤300 mA), and transient thermal impedance behavior under 180° sinusoidal conduction.
Technical Context
This thyristor operates in natural- or forced-commutated AC power circuits where precise phase-angle control of high-current loads is required. Its 125 °C maximum junction temperature, 250 µs circuit commutated turn-off time (tq), and 1000 V/µs critical dv/dt rating support robust operation in 50/60 Hz grid-connected systems with inductive loads.
The device uses a silicon pellet with pressure-contact construction and dual-sided cooling interface. Gate triggering is optimized for low-energy firing (≤2.2 V VGT, ≤250 mA IGT) while maintaining immunity to false turn-on via 0.25 V non-trigger gate voltage (VGD) and 10 mA non-trigger gate current (IGD) at full blocking voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1800 V - Maximum repetitive blocking voltage in forward/reverse direction at Tvj max, enabling use in 1380 V AC line applications with safety margin. |
| ITAVM (TC = 85 °C) | 880 A - Continuous DC or sine-wave average on-state current with two-sided heatsink cooling, defining steady-state power handling capability. |
| ITSM (tP = 10 ms) | 17500 A - Non-repetitive surge current rating, supporting short-circuit withstand in industrial drive DC-link protection. |
| (diT/dt)cr | 200 A/µs - Minimum required rate of rise of on-state current to avoid localized hot-spot formation during turn-on. |
| RthJC (two-sided) | 0.032 °C/W - Junction-to-case thermal resistance under optimal dual-face mounting, directly determining heatsink sizing for 85 °C case temperature limit. |
| VGT / IGT | 2.2 V / 250 mA - Maximum gate trigger voltage and current at 25 °C and 12 V anode voltage, defining minimum driver output capability. |
| tq | 250 µs - Typical commutated turn-off time at Tvj max, critical for minimum off-time in phase-controlled rectifier designs. |
Pinout & Package
Package: TO-240AA (also designated as "Press-Pack" or "Stud Mount") with isolated anode/cathode terminals and flat gate contact. Requires mechanical clamping force of 10.5–21 kN for reliable thermal and electrical contact.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Main current entry terminal | High-current path carrying full load current into device; electrically and thermally coupled to heatsink via pressure contact. |
| Cathode (2) | Main current exit terminal | Carries full on-state current out; symmetric thermal interface enables bidirectional cooling configuration. |
| Gate (4) | Control input for turn-on | Low-energy trigger terminal requiring ≤250 mA pulse; flat contact ensures stable gate drive connection under vibration. |
| Auxiliary Cathode (5) | Secondary cathode reference | Provides dedicated low-inductance return path for gate drive circuitry, improving noise immunity and triggering reliability. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact Si pellet | Enables direct metal-to-metal thermal path with <0.032 °C/W RthJC, eliminating bond wire failure modes in high-cycle industrial applications. |
| 125 °C maximum junction temperature | Supports continuous operation in ambient temperatures up to +85 °C with appropriate heatsinking, meeting industrial and traction-grade thermal requirements. |
| 250 µs turn-off time (tq) | Allows reliable commutation in 50/60 Hz phase-controlled rectifiers with ≥10 ms off-periods, preventing shoot-through in multi-pulse configurations. |
| 1000 V/µs critical dv/dt | Prevents spurious turn-on during rapid voltage transients in transformer-fed or long-cable motor drive systems without snubber networks. |
| 0.25 V gate non-trigger voltage (VGD) | Ensures immunity to noise-induced false triggering when anode voltage reaches 67% of VDRM, reducing risk of uncontrolled conduction. |

FAQ
What is the recommended gate drive circuit for T880N18TOFXPSA1?
A pulse-transformer or optocoupler-isolated gate driver delivering ≥1 A peak current for ≥20 µs duration is recommended. Gate resistor must limit IGT to ≤250 mA while ensuring VGT ≥2.2 V under worst-case temperature and supply conditions. Auxiliary cathode connection reduces ground loop noise.
Can T880N18TOFXPSA1 be used in forced-commutated circuits?
No - this device is designed exclusively for line-commutated (natural-commutation) operation. Its 250 µs tq and lack of integrated reverse-blocking capability make it unsuitable for chopper or inverter topologies requiring active turn-off. Use IGCTs or GTOs for forced-commutation.
What mechanical mounting torque is required for reliable thermal performance?
Clamping force must be maintained between 10.5 kN and 21 kN using calibrated torque tools and hardened washers. Under-torque increases RthJC beyond 0.032 °C/W; over-torque risks silicon fracture. Surface flatness ≤0.05 mm and Ra ≤0.8 µm on heatsink mating surfaces are mandatory.
Does T880N18TOFXPSA1 require snubber circuits in standard 50 Hz applications?
Snubbers are not required for basic 50/60 Hz phase control if dv/dt remains below 1000 V/µs and di/dt stays within 200 A/µs. However, RC snubbers are recommended when driving highly inductive loads or operating near VDRM limits to suppress voltage overshoot during commutation.
