Product details
Overview
ETT420N22P60HPSA1 from Infineon Technologies is a pressure-contact, dual-arm phase-control thyristor module rated for 2200 V repetitive peak off-state voltage (VDRM/VRRM), 427 A average on-state current at TC = 85°C (ITAVM), and 13.4 kA non-repetitive surge current (ITSM). It features electrically insulated AlN baseplate, 0.548 mΩ slope resistance (rT), and 0.0795 K/W junction-to-case thermal resistance per arm - designed for high-reliability industrial power control in soft starters and drive rectifiers.
For engineers reviewing the ETT420N22P60HPSA1 datasheet, ETT420N22P60HPSA1 pinout, ETT420N22P60HPSA1 application, or ETT420N22P60HPSA1 equivalent, key selection criteria include verified gate trigger parameters (IGT ≤ 250 mA, VGT ≤ 2.2 V), critical dv/dt rating (1000 V/µs), transient thermal impedance ZthJC profile, and mechanical mounting torque (M10, 6 Nm).
Technical Context
This dual-thyristor module implements forced-commutated phase-angle control with symmetrical forward/reverse blocking capability. Its pressure-contact die attachment enables stable thermal performance under high di/dt (150 A/µs) and dv/dt (1000 V/µs) stress, while the 60 mm insulated baseplate supports direct heatsink mounting without additional isolation hardware.
The device operates across -40°C to +135°C case temperature range and delivers 1.94 V max on-state voltage at 1700 A and Tj = 135°C. Its 280 µs typical turn-off time (tq) and 897.8 kA²s I²t rating support robust crowbar and static switch protection functions in UPS and battery charger systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 2200 V - Maximum repetitive blocking voltage in both directions; defines safe AC line voltage handling up to 1550 V RMS. |
| ITAVM (TC = 85°C) | 427 A - Continuous DC or sine-conduction average current per arm; sets thermal design baseline for heatsink sizing. |
| ITSM (10 ms) | 13400 A - Non-repetitive surge current capability; determines short-circuit withstand in motor start-up or fault conditions. |
| RthJC (per arm) | 0.0795 K/W - Junction-to-case thermal resistance under DC conduction; used with measured case temp to derive max junction temp. |
| (dvD/dt)cr | 1000 V/µs - Minimum critical rate-of-rise of off-state voltage before spurious turn-on; requires snubber design validation. |
| V(TO) / rT | 0.85 V / 0.548 mΩ - Threshold voltage and slope resistance; defines on-state conduction loss model VT = V(TO) + rT × IT. |
| tq (typ.) | 280 µs - Circuit commutated turn-off time at full current; constrains minimum pulse width and commutation circuit design. |
Pinout & Package
ETT420N22P60HPSA1 uses an industrial-standard press-pack module package with 60 mm × 124 mm electrically insulated AlN baseplate and M10 mounting screw pattern. Terminals are arranged in dual-arm configuration: two main AC terminals (T1/T2 per arm), two isolated gate terminals (G/K per arm), and baseplate as thermal reference and electrical isolation barrier.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| T1 (Arm 1) | Anode of first thyristor arm | High-side AC line connection point; rated for full ITAVM and ITSM; requires low-inductance busbar interface. |
| T2 (Arm 1) | Cathode of first thyristor arm | Load-side output for Arm 1; shares baseplate thermal path; must be isolated from Arm 2 cathode if not paralleled. |
| G1 / K1 | Gate and cathode control pair (Arm 1) | Isolated low-power control interface; 250 mA max trigger current; requires separate gate driver with <4 µs delay. |
| T1 (Arm 2) | Anode of second thyristor arm | Second AC line connection; enables full-bridge or anti-parallel configurations; electrically isolated from Arm 1 terminals. |
| T2 (Arm 2) | Cathode of second thyristor arm | Second load output; allows independent phase control per arm; baseplate serves as common thermal sink but not electrical node. |
| G2 / K2 | Gate and cathode control pair (Arm 2) | Independent gate drive path; identical specs to G1/K1; enables synchronized or staggered firing for harmonic reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure contact die attachment | Eliminates wire bonds and solder fatigue; maintains stable RthJC and di/dt capability over >10⁵ thermal cycles. |
| Electrically insulated AlN baseplate | 3.0 kV RMS insulation rating (1 min); enables direct mounting to grounded heatsinks without isolation pads or bushings. |
| Advanced Medium Power Technology (AMPT) | Optimized for 400–690 V AC industrial drives; balances conduction loss (0.85 V threshold), switching speed (280 µs tq), and ruggedness (13.4 kA ITSM). |
| Standardized mechanical footprint | Compatible with DIN 46244 A 2.8×0.8 mm control terminals and M10 mounting; simplifies replacement and board-level integration. |
| Full 180° conduction angle support | Rated ITAVM = 427 A at Θ = 180°; enables linear power control in soft starters without derating for partial conduction. |
Applications
| Soft Starter Systems | Drive Rectifier Modules |

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 |
|---|---|---|---|
| ETT420N22P60HPSA2 | Same die, identical ratings, but with updated internal production lot traceability and minor packaging revision (Revision 3.2 vs. 3.1). | No functional difference; qualified for same soft starter and drive rectifier designs. | Select when requiring latest manufacturing revision with extended lifecycle documentation. |
| TT420N22KOF | Single-arm variant (no dual-gate isolation); lower ITAVM (380 A @ TC=85°C); same VDRM and ITSM. | Limited to single-phase or half-bridge topologies; lacks independent arm control for B6 rectifiers. | Choose only for cost-sensitive single-arm applications where dual-arm functionality is unnecessary. |
Compared with ETT420N22P60HPSA1, the HPSA2 offers identical electrical and thermal performance with enhanced traceability, while TT420N22KOF sacrifices dual-arm flexibility and 47 A current headroom for reduced cost and footprint - making it unsuitable for B6 bridges or synchronized soft-start control.

FAQ
What is the maximum allowable case temperature for continuous operation?
The ETT420N22P60HPSA1 supports continuous operation up to TC = 135°C, as confirmed by its thermal derating curves on page 7 of the technical information document. At this temperature, ITAVM remains 427 A for 180° conduction, provided RthCH (case-to-heatsink) is ≤ 0.03 K/W and ambient cooling maintains stable baseplate temperature.
Does this module require external snubbers for standard 50/60 Hz operation?
Yes - due to its 1000 V/µs critical dv/dt rating, external RC snubbers are required across each thyristor arm when switching inductive loads or operating near VDRM. The datasheet specifies snubber design guidelines on page 6, recommending dv/dt suppression to <500 V/µs for reliable gate-controlled turn-on without false triggering.
Can both arms be triggered simultaneously for parallel current sharing?
No - the arms are electrically isolated but thermally coupled; simultaneous triggering is possible only if gate drive timing matches within ±0.5 µs and current sharing is balanced via external busbar symmetry and matching dynamic impedance. The device is not characterized for forced parallel operation; use per-arm control for B6 or anti-parallel topologies instead.
What is the gate drive power requirement for reliable turn-on?
Peak gate power must reach ≥20 W for 10 ms (curve "a" on page 6), with gate trigger current ≤250 mA and voltage ≤2.2 V at 12 V anode-cathode bias. Gate drivers must deliver ≥1 A peak current for latching (IL = 1500 mA), and maintain ≥300 mA holding current (IH) until load current exceeds ITAVM threshold.
