Product details
Overview
TD700N22KOFHPSA1 from Infineon Technologies is a press-pack, double-sided, phase-control thyristor module rated for 2200 V repetitive peak off-state voltage (VDRM/VRRM), 700 A average on-state current at TC = 85°C (ITAVM), 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 TD700N22KOFHPSA1 datasheet, TD700N22KOFHPSA1 pinout, TD700N22KOFHPSA1 application, or TD700N22KOFHPSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.046 K/W), critical dv/dt rating (1000 V/µs), gate trigger current (≤250 mA), and pressure-contact construction enabling high-reliability operation in crowbar and static switch circuits.
Technical Context
This thyristor module implements a dual-arm, anti-parallel configuration with isolated gate terminals per arm, supporting line-commutated AC phase control. Its pressure-contact die attachment ensures stable thermal performance under high di/dt (200 A/µs) and high dv/dt (1000 V/µs) transients typical in drive rectifier and bypass switch applications.
The device operates with a threshold voltage (VT0) of 0.85 V and slope resistance (rT) of 0.35 mΩ at maximum junction temperature, delivering predictable on-state conduction loss up to 1050 A RMS (ITRMSM). Its 135°C maximum junction temperature and 60 mm baseplate support integration into forced-air or liquid-cooled industrial power assemblies.

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 | No pre-applied TIM; requires external thermal interface; identical electrical specs and package footprint. | Suitable where TIM selection is customer-defined or thermal cycling profile demands custom grease formulation. | Select TT700N22KOF when TIM process control, rework flexibility, or qualification against specific thermal pastes is required. |
| TD700N22KOFS | Same core die and package, but uses standard (non-pre-applied) TIM process and different datecode/sourcing traceability. | Used in legacy OEM designs where procurement history mandates exact historical revision tracking. | Choose TD700N22KOFS only if backward compatibility with prior production lots or SAP material mapping is mandatory. |
Compared with TT700N22KOF and TD700N22KOFS, TD700N22KOFHPSA1 delivers immediate thermal readiness out-of-box, reduces assembly steps by eliminating TIM dispensing, and improves batch-to-batch thermal impedance consistency-critical for high-volume UPS and soft starter manufacturing.

FAQ
What is the maximum allowable junction temperature for TD700N22KOFHPSA1?
The maximum junction temperature (Tvj max) is 135°C, validated per IEC 60747-6. Operation beyond this limit risks irreversible degradation of the silicon die and pressure-contact interface. Thermal design must ensure junction temperature remains below 135°C under worst-case ambient, load, and cooling conditions.
Does TD700N22KOFHPSA1 require external gate resistors for reliable triggering?
No external gate resistor is required for basic triggering, as the device specifies IGT ≤250 mA and VGT ≤2.2 V at 25°C. However, a 10–22 Ω series resistor is recommended to dampen ringing and limit peak gate current during fast edge transitions in noisy industrial environments.
Can TD700N22KOFHPSA1 be used in single-phase applications?
Yes-it supports single-phase configurations including half-wave and full-wave (bridge) rectification, soft starting, and static switching. Its dual-arm structure allows flexible connection as two independent thyristors or as a back-to-back pair for AC voltage control without reverse-blocking diodes.
What is the creepage distance and insulation rating of the baseplate?
The creepage distance is 19 mm, and the baseplate provides reinforced insulation rated for 3.6 kV RMS (1 second) and 3.0 kV RMS (1 minute) per IEC 60664-1. This meets Class 1 safety requirements and enables direct mounting on grounded metal heatsinks without additional insulating hardware.
