Product details
Overview
ETT630N18P60XPSA1 from Infineon Technologies is a press-pack, double-sided cooled phase-control thyristor module rated for 1800 V repetitive peak off-state voltage (VDRM/VRRM), 628 A average on-state current at TC = 85°C (ITAVM), and 20 kA non-repetitive surge current (ITSM). It features electrically insulated baseplate, pressure-contact silicon pellet construction, and Advanced Medium Power Technology (AMPT) for high reliability in industrial power control circuits.
For engineers reviewing the ETT630N18P60XPSA1 datasheet, ETT630N18P60XPSA1 pinout, ETT630N18P60XPSA1 application, or ETT630N18P60XPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.0575 K/W), threshold voltage (0.8 V), slope resistance (0.341 mΩ), gate trigger current (≤250 mA), and critical dv/dt rating (1000 V/µs) in high-noise drive and crowbar systems.
Technical Context
This thyristor module implements a dual-arm, anti-parallel configuration optimized for line-commutated AC phase control. Its pressure-contact die assembly enables low thermal resistance and high surge robustness, with validated turn-off time (tq = 270 µs typ.) under 100 V reverse recovery conditions and 20 A/µs commutation di/dt.
The device operates with DC or sinusoidal conduction angles from 30° to 180°, supporting both B2 (two-pulse) and B6 (six-pulse) bridge topologies. Gate triggering is specified at 12 V anode-cathode voltage, with latching current ≤1500 mA and holding current ≤300 mA - enabling reliable firing in soft-start and static switch applications without auxiliary snubbers.
Key Specifications

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 |
|---|---|---|---|
| ETT630N18P60XPSA2 | Same electrical specs; differs only in datecode and internal production order tracking (DMX digit positions 13–24) | No functional difference; identical thermal, electrical, and mechanical behavior in all applications | Select when traceability to specific production lot or week is required for quality audits |
| eTD630N18P60 | Identical VDRM/VRRM (1800 V), ITAVM (628 A), and RthJC (0.0575 K/W); differs in gate trigger sensitivity (IGT ≤ 200 mA vs. 250 mA) | Better suited for low-power gate drivers; otherwise interchangeable in soft starters and static switches | Prefer when driving with microcontroller-based gate drivers lacking 250 mA peak output capability |
Compared with ETT630N18P60XPSA1, the XPSA2 variant offers identical performance with enhanced lot-level traceability, while eTD630N18P60 provides marginally lower gate drive demand - making it advantageous in space-constrained or low-power-control designs without sacrificing surge or thermal capability.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum allowable case temperature (TC) is +135°C, aligned with the maximum junction temperature (Tvj max = 135°C) and zero thermal resistance between case and junction under DC conduction. Derating curves on page 7 of the technical information show ITAVM decreases to 300 A at TC = 100°C for Θ = 180° sinusoidal conduction, confirming thermal design margins must respect this limit.
Does ETT630N18P60XPSA1 require forced cooling?
Forced cooling is not mandatory but strongly recommended above 300 A ITAVM. At 628 A ITAVM and TC = 85°C, the module dissipates ~1.8 kW per arm (calculated from PTAV curves), requiring a heatsink with RthCA ≤ 0.15 K/W - achievable only with forced air or liquid cooling per the thermal diagrams on pages 7–8 of the datasheet.
Can this module be used in single-phase applications?
Yes - ETT630N18P60XPSA1 supports single-phase configurations including B2 two-pulse bridges and single-arm phase controllers. Its dual-arm anti-parallel structure allows full-wave AC control, and the 1800 V VDRM rating accommodates 1000 V peak line voltages common in 700 V AC industrial systems.
What is the creepage distance and insulation class?
The creepage distance is 19 mm, and the module provides basic insulation (Class 1 per IEC 61140) using an aluminum nitride (AlN) ceramic substrate. It achieves 3.6 kV RMS insulation test voltage for 1 second, enabling direct mounting to grounded heatsinks without supplemental isolation barriers in UL/EN-compliant equipment.
