Infineon Technologies ETD480N22P60HPSA1

Overview

ETD480N22P60HPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching in industrial power controllers and soft starters. It delivers 480 A average on-state current (ITAVM) at TC = 85°C, 2200 V repetitive peak off-state voltage (VDRM/VRRM), and 14.7 kA non-repetitive surge current (ITSM), operating with electrically insulated base plate and pressure-contact die attachment for thermal and mechanical robustness in drive rectifier applications.

For engineers reviewing the ETD480N22P60HPSA1 datasheet, ETD480N22P60HPSA1 pinout, ETD480N22P60HPSA1 application, or ETD480N22P60HPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.0705 K/W), gate trigger current (≤250 mA), critical dv/dt rating (1000 V/µs), and RMS on-state current capability (700 A) under sinusoidal conduction.

Technical Context

This dual-thyristor, press-pack module implements phase-angle control in AC power circuits using two anti-parallel thyristor chips mounted on an AlN-insulated 60 mm base plate. Its design supports forced-air or liquid-cooled heatsinking, with validated turn-off time (tq = 300 µs typ.) and commutation-safe operation under 100 V reverse recovery voltage and 20 V/µs dv/dt stress.

The module features gate-controlled delay time ≤4 µs, threshold voltage ≤0.85 V, and slope resistance ≤0.484 mΩ - enabling precise firing-angle control and low conduction losses in high-current rectification and crowbar protection circuits where thermal stability and isolation integrity are mission-critical.

FAQ

What is the maximum allowable junction temperature for ETD480N22P60HPSA1?

The maximum junction temperature (Tvj max) is 135°C, as specified in the official Infineon technical information document revision 3.1. Operation beyond this limit risks irreversible degradation of the silicon die and pressure-contact interface. Thermal design must ensure that under worst-case ITAVM and ambient conditions, junction temperature remains below 135°C using the provided RthJC (0.0705 K/W) and RthCH (0.03 K/W) values.

Does ETD480N22P60HPSA1 require gate resistors for reliable triggering?

Yes - a series gate resistor (typically 10–33 Ω) is required to limit peak gate current and shape the gate pulse edge, preventing localized heating at the gate-cathode junction. The datasheet specifies maximum gate trigger current (IGT ≤ 250 mA) and non-trigger current (IGD ≤ 10 mA), so resistor selection must ensure gate drive stays within these bounds while maintaining diG/dt ≥ 1 A/µs for reliable turn-on.

Can ETD480N22P60HPSA1 be used in single-phase versus three-phase configurations?

Yes - the dual-arm architecture supports both configurations: as a single-phase back-to-back pair (B2) for AC voltage control, or as one leg of a three-phase six-pulse bridge (B6). Derating curves in the datasheet explicitly show ITAVM vs. conduction angle for both 180° sinewave and rectangular waveforms, confirming validated use in either topology with appropriate heatsinking and gate drive synchronization.

What is the creepage distance and why does it matter for this module?

The creepage distance is 19 mm, measured across the insulated base plate surface between high-voltage terminals. This value meets IEC 61800-5-1 requirements for Pollution Degree 3 environments, ensuring safe operation in dusty, humid, or conductive-contaminant industrial settings. It directly impacts system-level insulation coordination and determines minimum spacing requirements on PCBs or busbars when mounting adjacent modules.
