- High surge capability utilizing glass passivated chips
- Industrial standard New INT-A-pak power module package
Applications
- DC motor control and drives
- Battery chargers
- Welders
- Power converters
- Lighting control systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's Bulletin I27117 rev. C to confirm the exact circuit configuration and voltage code. Ensure that thermal interface materials are compatible with the NEW INT-A-PAK case style. Confirm UL E78996 approval status if required for end-product certification. Check for optional hardware availability per Bulletin I27900.
Selection Notes
Select this component based on the 160 A average on-state current rating and 800 V blocking voltage requirements. Consider the 3500 V RMS isolation voltage for safety-critical applications. Evaluate thermal management needs using the provided RthJC values and power loss characteristics. Verify compatibility with the intended conduction angles and surge current demands.
Part Context
This part belongs to the IRK.136, .142, and .162 series of high-voltage thyristor modules. These modules utilize high-voltage power thyristors and diodes in various configurations. The series is designed for industrial power applications requiring robust performance and reliable switching capabilities under high current and voltage conditions.
Replacement Considerations
Consult official documentation for confirmed substitute part numbers within the same series or equivalent product lines. Ensure any replacement matches the IT(AV), VRRM, and package dimensions. Verify thermal resistance and isolation voltage specifications before implementation.
