IXGH85N30C3

Overview

The IXYS IXGH85N30C3 is an N-channel Insulated Gate Bipolar Transistor (IGBT) belonging to the GenX3 power device series. It utilizes XPT (eXtended Plate Technology) to optimize switching performance and conduction losses. The component features a TO-247AD three-pin through-hole package designed for high-power industrial applications. Key electrical specifications include a collector-emitter breakdown voltage of 300V and a continuous collector current rating of 85A at case temperature. The device incorporates an integrated anti-parallel fast recovery diode, functioning as a reverse-conducting IGBT (RC-IGBT). This configuration eliminates the need for external freewheeling diodes in bridge circuits, simplifying design and reducing parasitic inductance.

Feature Summary

• Integrated anti-parallel fast recovery diode for reverse conduction capability
• GenX3 trench gate technology for optimized switching characteristics
• XPT structure providing square Reverse Bias Safe Operating Area (RBSOA)
• Short-circuit withstand capability for robust system protection

Applications

• High-frequency induction heating systems
• Motor drive inverters and servo amplifiers
• Uninterruptible Power Supplies (UPS) and DC-AC converters
• Switched-mode power supplies (SMPS) requiring high efficiency

Procurement Notes

Verify the specific suffix 'C3' against the manufacturer's latest datasheet to confirm pinout compatibility and thermal characteristics. Ensure the procurement channel provides original packaging with intact moisture barrier indicators. Check for RoHS compliance documentation if required by regional regulations. Confirm that the supplier offers traceability certificates matching the lot codes on the physical components.

Selection Notes

Select this component when designing circuits requiring integrated freewheeling functionality to minimize board space and parasitic inductance. Evaluate the thermal resistance parameters against the expected junction temperature limits under maximum load conditions. Consider the switching frequency capabilities relative to the application's power loss constraints. Verify that the gate drive circuitry can handle the total gate charge requirements for efficient turn-on and turn-off transitions.

Part Context

This device is part of IXYS's GenX3 portfolio, which represents a generation of trench-gate IGBTs offering improved switching speed compared to previous planar technologies. The XPT technology distinguishes it by enabling higher blocking voltages with lower saturation voltage, enhancing overall system efficiency. It serves as a critical power switching element in medium-voltage AC drives and resonant converter topologies where compactness and reliability are paramount.

Replacement Considerations

Potential substitutes must match the 300V/85A rating and TO-247AD package. Verify if alternative RC-IGBTs from other manufacturers provide compatible gate threshold voltages and thermal resistance values. Ensure any replacement maintains the same short-circuit rating and diode recovery characteristics to avoid circuit instability.
