Product details
Overview
T2480N28TOFVTXPSA1 from Infineon Technologies is a high-power, phase-control thyristor designed for industrial AC power regulation in medium- to high-voltage line-commutated converters. It delivers 2800 V repetitive peak off-state voltage (VDRM/VRRM), 5610 A RMS on-state current (ITRMS), and 47.5 kA non-repetitive surge current (ITSM) at 10 ms, enabling robust operation in HVDC converter valves, static VAR compensators, and large motor soft starters.
For engineers reviewing the T2480N28TOFVTXPSA1 datasheet, T2480N28TOFVTXPSA1 pinout, T2480N28TOFVTXPSA1 application, or T2480N28TOFVTXPSA1 equivalent, key selection criteria include verified gate trigger current (≤250 mA), critical dv/dt rating (1000 V/µs), junction-to-case thermal resistance (0.0078 °C/W two-sided), and validated 125 °C maximum junction temperature under full conduction.
Technical Context
This thyristor employs a pressure-contact silicon pellet structure with dual-sided cooling capability and is optimized for forced-commutated or line-commutated turn-off in high-energy AC systems. Its 400 µs typical circuit commutated turn-off time (tq) and 200 A/µs critical di/dt rating support reliable triggering and commutation in 50/60 Hz grid applications with inductive loads.
The device features a defined on-state characteristic (vT = A + B·iT + C·ln(iT) + D·iT²) with slope resistance of 0.154 mΩ and threshold voltage of 0.95 V at maximum junction temperature - enabling precise conduction loss modeling across 600–12,500 A operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 2800 V - Maximum repetitive blocking voltage in forward and reverse directions, defining safe AC line voltage rating up to 2 kV RMS. |
| ITRMS | 5610 A - RMS on-state current capacity under sinusoidal 180° conduction, determining continuous thermal handling with two-sided heatsinking. |
| ITSM (10 ms) | 47500 A - Non-repetitive surge current withstand, supporting short-circuit ride-through in converter valve stacks. |
| (dv/dt)cr | 1000 V/µs - Minimum critical rate-of-rise of off-state voltage before spurious turn-on, ensuring noise immunity in high-dv/dt environments. |
| RthJC (two-sided) | 0.0078 °C/W - Junction-to-case thermal resistance with bilateral cooling, enabling accurate junction temperature prediction under 3570 A average current at TC = 55 °C. |
| tq (typ.) | 400 µs - Typical line-commutated turn-off time at full current, setting minimum commutation interval in phase-controlled rectifiers. |
| vT (iT = 6.5 kA) | 2.0 V - On-state voltage at peak rated conduction, directly determining conduction losses (~13 kW at 6.5 kA). |
Pinout & Package
Package: TO-280AA (pressure-contact, disc-type thyristor with clamping assembly). Two-sided cooling interface; anode and cathode surfaces are electrically active and thermally conductive. Gate terminal is flat-profile, auxiliary cathode present for enhanced control reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (1) | Main power input (AC line or DC bus positive) | High-current, high-voltage terminal; must be mounted with ≥42 kN clamping force to ensure low-resistance thermal and electrical contact. |
| Cathode (2) | Main power output (load return or DC bus negative) | Carries full load current; symmetric thermal path enables bidirectional heatsinking when used with auxiliary cathode. |
| Gate (4) | Control input for triggering conduction | Low-energy trigger interface requiring ≤250 mA pulse; sensitive to dv/dt - requires snubber or RC network in high-noise converters. |
| Auxiliary Cathode (5) | Secondary cathode connection for gate control stability | Improves gate-cathode coupling uniformity and reduces risk of localized misfiring during high-di/dt turn-on events. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure-contact Si pellet | Enables scalable current handling (up to 5610 A RMS) without wire bonds, eliminating bond fatigue failure modes in cyclic thermal stress. |
| Two-sided thermal interface | 0.0078 °C/W RthJC allows 3570 A ITAV at TC = 55 °C - doubling usable current vs. single-sided mounting for same heatsink footprint. |
| Validated 125 °C Tj max | Supports operation in ambient temperatures up to +125 °C case temperature, meeting industrial and traction converter derating requirements. |
| 400 µs tq with 100 V reverse recovery | Ensures reliable commutation in 50 Hz systems with ≥5 ms natural zero-crossing intervals, reducing need for forced commutation circuits. |
| 1000 V/µs (dv/dt)cr | Permits direct use in 6.6 kV AC systems with standard RC snubbers - no active dv/dt suppression required for typical grid harmonics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT2480N28KOF | Same VDRM/VRRM (2800 V) and ITRMS (5610 A), but uses KO package with integrated heat spreader and lower RthJC (0.0072 °C/W); gate trigger current higher (300 mA max). | Preferred for space-constrained designs where thermal interface uniformity is critical; less tolerant of marginal gate drive strength. | Select when thermal margin is prioritized over gate drive simplicity; verify gate driver can source 300 mA peak. |
| T2480N28TOFVTXPSA2 | Identical mechanical and electrical specs, but qualified to AEC-Q101 automotive grade with extended temperature validation (-40 °C to +150 °C storage). | Suitable for rail traction converters requiring automotive-grade reliability documentation; no performance difference in industrial use. | Choose only if OEM program mandates AEC-Q101 compliance; otherwise, PSA1 offers identical functionality at lower cost. |

FAQ
What is the recommended gate drive circuit for T2480N28TOFVTXPSA1?
A pulse transformer or isolated gate driver delivering ≥1 A peak gate current for ≥20 µs is required to ensure reliable turn-on across temperature and aging. The gate trigger voltage must exceed 2.5 V (max) at 25 °C, and the non-trigger voltage limit is 0.25 V - necessitating tight noise filtering on the gate loop. Snubber networks with 100 Ω/0.1 µF are advised for dv/dt > 500 V/µs environments.
Can T2480N28TOFVTXPSA1 be used in parallel configurations?
Yes, but only with matched dynamic parameters (vT, tq, and (di/dt)cr) and forced current sharing via external balancing reactors or active gate control. The datasheet specifies a maximum gate non-trigger current of 10 mA at Tvj max, so gate isolation between paralleled units is mandatory to prevent cross-triggering or uneven current division.
What is the maximum allowable clamping force during module assembly?
The specified clamping force range is 42–95 kN. Exceeding 95 kN risks silicon pellet fracture or metallization damage, while forces below 42 kN increase contact resistance, raising local junction temperature and accelerating thermal runaway. Force must be applied uniformly using calibrated hydraulic presses with parallelism tolerance ≤0.05 mm.
Does T2480N28TOFVTXPSA1 require forced cooling?
For continuous operation above 1800 A ITAV (sinusoidal, 180°), forced cooling (liquid or high-velocity air) is mandatory to maintain TC ≤ 85 °C. With two-sided natural convection, the device sustains only ~950 A ITAV; the 0.0078 °C/W RthJC assumes full thermal interface coverage and surface flatness ≤1.6 µm Ra on both anode and cathode sides.
