Product details
Overview
TD340N22KOFXPSA1 from Infineon Technologies is a phase-control thyristor module designed for high-power AC line switching and rectification in industrial drive systems. It features 2200 V repetitive peak off-state voltage (VDRM/VRRM), 338 A average on-state current at TC = 85°C, and 9500 A non-repetitive surge current (ITSM), with electrically insulated baseplate and pressure-contact die attachment for thermal and mechanical robustness. It is deployed in soft starters and static power controllers operating at 50/60 Hz line frequencies.
For engineers reviewing the TD340N22KOFXPSA1 datasheet, TD340N22KOFXPSA1 pinout, TD340N22KOFXPSA1 application, or TD340N22KOFXPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.1 K/W), gate trigger current (≤200 mA), critical dv/dt rating (1000 V/µs), and isolation test voltage (3.6 kV for 1 sec).
Technical Context
This dual-thyristor module implements a press-pack, double-sided cooled design with AlN-based electrical insulation and a 50 mm baseplate. Its pressure-contact technology eliminates wire bonds and solder layers, enabling stable thermal performance under high di/dt (250 A/µs) and repeated surge stress.
The device operates in phase-controlled mode with precise gate triggering (tgd ≤ 3 µs) and supports conduction angles from 30° to 180° in both sinusoidal and rectangular current waveforms. Its transient thermal impedance ZthJC is characterized analytically for accurate loss modeling in dynamic load profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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 |
|---|---|---|---|
| TT340N22KOF | Same silicon die and thermal specs, but non-insulated baseplate requiring external isolation kit. | Requires additional insulating hardware and tighter layout clearance; unsuitable for direct-grounded heatsink mounting. | Select when cost-sensitive designs allow added assembly steps and have space for isolation accessories. |
| TD330N22KOF | Lower ITAVM (310 A @ TC = 85°C) and higher RthJC (0.107 K/W per arm); identical VDRM and package outline. | Derates to ~92% of TD340N22KOFXPSA1's continuous current capacity under same cooling conditions. | Choose only if thermal margin exists and peak surge requirements remain within 8000 A (ITSM) limit. |
Compared with TT340N22KOF and TD330N22KOF, TD340N22KOFXPSA1 provides superior thermal performance (0.1 K/W vs. 0.107 K/W), integrated baseplate isolation (no external insulator needed), and highest surge rating (9500 A), making it optimal for space-constrained, high-reliability industrial power controls.

FAQ
What is the maximum allowable junction temperature for TD340N22KOFXPSA1?
The maximum junction temperature (Tvj max) is 135°C, as specified in the Infineon technical information document revision 3.2. This limit governs thermal design margins and must be respected during steady-state and transient operation to prevent parametric drift or premature failure.
Does TD340N22KOFXPSA1 require external gate resistors?
Yes - gate resistors (typically 10–33 Ω) are required to limit peak gate current and ensure clean turn-on without oscillation. The datasheet specifies maximum gate trigger current (IGT ≤ 200 mA) and non-trigger current (IGD ≤ 10 mA), necessitating controlled gate drive impedance.
Can TD340N22KOFXPSA1 be used in parallel configurations?
No - this module is not characterized or recommended for paralleling. Its pressure-contact construction and lack of built-in current-sharing features (e.g., emitter ballasting or matched VTO) make forced current sharing unreliable without external active balancing circuitry.
What is the creepage distance specification for TD340N22KOFXPSA1?
The creepage distance is 17 mm, measured between main power terminals and the insulated baseplate, complying with IEC 61140 Class 1 basic insulation requirements for industrial equipment operating at up to 1000 V RMS mains voltage.
