- Thick copper baseplate combined with Al2O3 DBC insulator for superior mechanical ruggedness and thermal spread
- UL E78996 approved with 3500V RMS isolating voltage between circuit and base
- Generation V Add-A-pak design eliminates hard mold stress on leads
Applications
- High voltage regulated power supplies
- Lighting circuits
- Temperature control circuits
- Motor speed control circuits
- UPS systems and battery chargers
Procurement Notes
Verify the specific configuration code suffix against the ordering table in Bulletin I27133. Confirm that the dv/dt rating matches application requirements, as standard versions are rated at 500 V/µs while S90 variants offer 1000 V/µs. Ensure mounting torque specifications are strictly followed to maintain the integrity of the isolation voltage and thermal interface.
Selection Notes
Select based on required blocking voltage within the 400V to 1600V range and the necessary surge current capability. Consider the thermal resistance characteristics when designing heatsink interfaces, noting the internal junction-to-case resistance. Verify gate triggering requirements against the specified maximum gate currents and voltages across the operating temperature range.
Part Context
This component belongs to the IRK.105 series of high-power thyristor modules. The 'T' designation indicates a Thyristor/Diode configuration, while '106' specifies the current code and '14' denotes the 1400V voltage rating. These modules are designed for general-purpose high-voltage applications requiring robust mechanical construction and reliable switching performance.

FAQ
What is the maximum repetitive peak off-state voltage?
The maximum repetitive peak off-state voltage (VRRM) is 1400V.
How is the isolation voltage defined?
The module provides 3500V RMS isolation voltage for one second or 2500V RMS for one minute at 50Hz between the circuit terminals and the base.
What is the maximum rate of rise of off-state voltage?
The critical rate of rise of off-state voltage (dv/dt) is 500 V/µs at a junction temperature of 130°C with the gate open circuit.
