Product details
Overview
TD520N22KOFXPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial power electronics. It delivers 520 A average on-state current (ITAVM) at TC = 85 °C, 2200 V repetitive peak off-state voltage (VDRM/VRRM), and 18 kA non-repetitive surge current (ITSM), operating up to 125 °C junction temperature. It is used in soft starters, static switches, and UPS rectifiers requiring robust, press-pack reliability.
For engineers reviewing the TD520N22KOFXPSA1 datasheet, TD520N22KOFXPSA1 pinout, TD520N22KOFXPSA1 application, or TD520N22KOFXPSA1 equivalent, this module's pressure-contact construction, insulated baseplate, pre-applied TIM option, and dual-arm configuration are critical for thermal management and isolation in medium-power drive systems.
Technical Context
This thyristor module integrates two anti-parallel thyristor chips in a single press-pack housing with electrically isolated aluminum nitride (AlN) baseplate. Its gate trigger characteristics require ≤250 mA IGT and ≤2.2 V VGT at 25 °C, with critical di/dt capability of 200 A/µs and dv/dt rating of 1000 V/µs at maximum junction temperature.
Thermal design relies on low RthJC (0.055 K/W per module, DC) and optional pre-applied TIM reducing RthCH to 0.0075 K/W. The module supports conduction angles from 30° to 180°, with transient thermal impedance ZthJC modeled analytically for accurate loss calculation under sinusoidal and rectangular load currents.
Key Specifications

Pinout & Package
TD520N22KOFXPSA1 uses an industrial-standard press-pack module package with 60 mm × 60 mm baseplate, AlN insulation, and M1 (6 Nm) mechanical mounting. Terminals include two main AC power terminals (anode/cathode per arm), two gate control terminals (G/K), and an isolated baseplate serving as thermal and electrical reference.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 / K1 | Main terminal pair for Arm 1 | Carries full-phase current in one direction; configured anti-parallel with Arm 2 for bidirectional AC control. |
| A2 / K2 | Main terminal pair for Arm 2 | Enables reverse conduction path; paired with Arm 1 to form full-wave phase-controlled bridge or static switch. |
| G1 / K1 | Gate control for Arm 1 | Receives pulsed trigger signal (≤250 mA, ≤2.2 V); referenced to K1, not baseplate or other arm. |
| G2 / K2 | Gate control for Arm 2 | Independent gate drive required; no shared gate connection - enables asymmetric or sequential firing control. |
| Baseplate | Electrically isolated thermal interface | AlN-insulated surface rated 3.0 kV isolation; serves as heatsink interface and safety barrier, not circuit ground. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure contact technology | Eliminates wire bonds and solder joints, enabling >10⁶ power cycles and stable contact resistance under thermal cycling. |
| Pre-applied TIM option | Reduces case-to-heatsink thermal resistance to 0.0075 K/W per module, minimizing thermal interface assembly steps and variability. |
| Electrically insulated baseplate | AlN ceramic layer provides 3.0 kV RMS isolation, allowing direct mounting to grounded heatsinks without external insulation kits. |
| Advanced Medium Power Technology (AMPT) | Optimized chip layout and gate structure deliver 200 A/µs di/dt immunity and <4 µs gate delay, supporting fast-switching phase control. |
| Dual-arm anti-parallel configuration | Enables bidirectional AC switching in single-package footprint, reducing system size vs. discrete thyristor pairs with external isolation. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TT520N22KOF | Same die, identical electrical specs, but non-TIM version with higher RthCH (0.01 K/W vs. 0.0075 K/W). | No pre-applied TIM; requires user-applied thermal interface and tighter torque control for optimal RthCH. | Select when thermal interface material is standardized in-house and process control ensures consistent mounting pressure. |
| TD520N22KOFTMA1 | Includes integrated temperature sensor (NTC) on baseplate; otherwise matches TD520N22KOFXPSA1 electrically and thermally. | Enables closed-loop thermal monitoring and overtemperature shutdown in safety-critical drives and UPS systems. | Select when real-time junction temperature estimation or functional safety compliance (e.g., IEC 61800-5-2) is required. |

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (TC) is +125 °C, aligned with the 125 °C maximum junction temperature (Tvj max). Derating curves in the datasheet show ITAVM decreases to ~300 A at TC = 125 °C for 180° conduction, requiring active cooling or reduced load in high-ambient environments.
Is the baseplate electrically connected to any internal terminal?
No-the baseplate is fully electrically isolated via an aluminum nitride (AlN) ceramic layer rated for 3.0 kV RMS isolation. It serves solely as a thermal interface and must not be used as a circuit node or ground reference for gate signals or power paths.
Can TD520N22KOFXPSA1 be used in a single-phase full-wave bridge?
Yes-it contains two independent, anti-parallel thyristor arms, making it suitable for single-phase full-wave phase control. Each arm handles one polarity; gate signals must be isolated and timed separately to avoid shoot-through during commutation.
What gate drive requirements must be met for reliable triggering?
Gate pulses must deliver ≥1 A peak current with diG/dt ≥1 A/µs and duration ≥20 µs to ensure latching (IL ≤1500 mA). Trigger voltage must exceed VGT (≤2.2 V) at 12 V anode-cathode voltage; gate-cathode non-trigger leakage (IGD ≤10 mA) must be respected in high-noise industrial environments.
