Product details
Overview
TD700N22KOFXPSA1 from Infineon Technologies is a press-pack, dual-arm phase-control thyristor module rated for 2200 V repetitive peak off-state voltage (VDRM/VRRM), 700 A average on-state current (ITAVM) at TC = 85°C, and 20.4 kA non-repetitive surge current (ITSM). It features electrically insulated baseplate, pre-applied thermal interface material (TIM), and Advanced Medium Power Technology (AMPT) for industrial power control in soft starters and UPS rectifiers.
For engineers reviewing the TD700N22KOFXPSA1 datasheet, TD700N22KOFXPSA1 pinout, TD700N22KOFXPSA1 application, or TD700N22KOFXPSA1 equivalent, this module's validated junction-to-case thermal resistance (0.046 K/W per arm), critical dv/dt rating (1000 V/µs), gate trigger threshold (≤2.2 V), and crowbar-capable surge handling are key selection criteria in high-reliability AC power switching designs.
Technical Context
This dual-thyristor module implements symmetrical, gate-controlled phase-angle switching in AC line-commutated topologies. Its pressure-contact construction ensures stable thermal and electrical performance under high di/dt (200 A/µs) and dv/dt stress, with verified turn-off time (tq = 260 µs typ.) at full-rated current and voltage conditions.
The module supports both single- and three-phase bridge configurations (B2/B6), delivering up to 1050 A RMS on-state current (ITRMSM) and sustaining 3.6 kV insulation test voltage (1 sec). Its analytical ZthJC transient thermal model enables precise loss and temperature prediction across conduction angles from 30° to 180°.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 2200 V - Maximum repetitive blocking voltage per arm; defines maximum AC line voltage compatibility (e.g., 1.15 kV RMS systems). |
| ITAVM (TC = 85°C) | 700 A - Continuous DC-equivalent current per arm; sets steady-state thermal design basis for heatsink sizing. |

Pinout & Package
TD700N22KOFXPSA1 is housed in an industrial-standard press-pack module with electrically insulated AlN-ceramic baseplate (60 mm × 60 mm footprint), rated for 3.6 kV isolation. Mechanical mounting uses M1 screws (6 Nm torque); electrical terminals use M2 screws (12 Nm torque) with DIN 46244 A 2.8 × 0.8 mm² cross-section.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (Anode 1) | Main anode of first thyristor arm | Carries full forward current in half-wave or B2/B6 rectifier configurations; requires low-inductance busbar connection. |
| K1 (Cathode 1) | Main cathode of first thyristor arm | Common return path for arm 1; electrically isolated from baseplate; connects to load or bridge midpoint. |
| A2 (Anode 2) | Main anode of second thyristor arm | Enables complementary conduction in full-wave phase control; matched thermal path to A1 for balanced current sharing. |
| K2 (Cathode 2) | Main cathode of second thyristor arm | Provides independent cathode node for dual-arm operation; supports asymmetrical firing in specialized controllers. |
| G1, K1G | Gate and cathode control terminals for arm 1 | Isolated low-power interface (≤250 mA IGT); requires separate gate driver with <4 µs delay for synchronized triggering. |
| G2, K2G | Gate and cathode control terminals for arm 2 | Galvanically separated from G1/K1G; enables independent or complementary gating for advanced firing sequences. |
Key Features
| Feature | Design Value |
|---|---|
| Pressure contact technology | Eliminates wire bonds and solder joints; maintains stable RthJC and on-state voltage over >10⁵ thermal cycles. |
| Pre-applied TIM | Reduces effective RthCH by ≥25% vs. bare copper interface; eliminates manual TIM application error in production assembly. |
| Electrically insulated baseplate | 3.6 kV/1 sec isolation enables direct mounting on grounded heatsinks without additional insulation hardware. |
| Advanced Medium Power Technology (AMPT) | Optimized silicon layout and pellet metallization deliver 0.35 mΩ slope resistance (rT) and 0.85 V threshold voltage (VT0) at 135°C. |
| Validated tq = 260 µs | Guarantees reliable forced commutation in line-commutated inverters operating up to 400 Hz fundamental frequency. |

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 |
|---|---|---|---|
| TT700N22KOF | Same die, identical ratings, but non-insulated baseplate and no pre-applied TIM. | Requires external isolation kit and manual TIM application; unsuitable for direct-mount on grounded heatsinks. | Select TT700N22KOF only when cost sensitivity outweighs assembly labor and isolation safety requirements. |
| TD900N22KOFXPSA1 | Higher ITAVM (900 A), same VDRM, larger package (70 mm × 70 mm), RthJC = 0.036 K/W per arm. | Supports higher continuous power in space-constrained UPS or traction converters where thermal margin is critical. | Choose TD900N22KOFXPSA1 when system-level thermal modeling shows >10°C junction temp margin shortfall with TD700N22KOFXPSA1. |
Compared with TT700N22KOF, TD700N22KOFXPSA1 adds baseplate insulation and TIM for simplified thermal management and safety compliance; compared with TD900N22KOFXPSA1, it trades 200 A current headroom for smaller footprint and lower cost in mid-power soft starters and static switches.

FAQ
What is the maximum allowable junction temperature for TD700N22KOFXPSA1?
The maximum junction temperature (Tvj max) is 135°C, validated across all operating conditions including surge events. This rating is used with RthJC = 0.046 K/W and measured case temperature to compute real-time junction temperature during thermal design verification.
Does TD700N22KOFXPSA1 require external snubbers in standard B6 rectifier applications?
Snubbers are required only when circuit dv/dt exceeds 1000 V/µs - the device's critical (dvD/dt)cr rating. In typical 50/60 Hz B6 rectifiers with standard line inductance, passive RC snubbers are optional; however, they are mandatory in high-frequency PWM-fed line reactors or regenerative braking interfaces.
Can TD700N22KOFXPSA1 be used in asymmetrical firing configurations?
Yes - its galvanically isolated gate terminals (G1/K1G and G2/K2G) support independent triggering of each arm. This enables asymmetrical conduction angles for harmonic mitigation, reactive power control, or specialized motor braking waveforms without cross-talk or timing skew.
What is the creepage distance and why does it matter for this module?
The creepage distance is 19 mm, measured across the insulated baseplate surface between high-voltage terminals. This value satisfies IEC 61800-5-1 requirements for Pollution Degree 3 environments, ensuring safe operation in dusty, humid industrial enclosures without risk of surface tracking or flashover.
