PP100T120

Overview

The Powerex PP100T120 is a POW-R-PAK configurable IGBT-based power assembly rated for 100A continuous collector current and 1200V blocking voltage. It integrates F-series trench gate IGBTs with low conduction and switching losses, mounted on a forced air-cooled heatsink. The unit includes a DC-link capacitor bank of 3300 µF, isolated gate drive interfaces, and a control board providing overvoltage, undervoltage lockout, overcurrent, overtemperature, and short circuit detection. It supports DC bus voltages up to 800VDC and switching frequencies above 20kHz.

Feature Summary

• High performance IGBT inverter bridge utilizing advanced F-series trench gate technology
• Integrated gate drive with fault monitoring including overcurrent, overtemperature, and shoot-through prevention
• Low inductance laminated bus structure for improved electromagnetic compatibility
• Output current measurement and feedback capabilities for precise system control

Applications

• Motor control systems
• Power supply units
• Uninterruptible Power Supply (UPS)
• Three-phase inverters
• Converters and choppers

Procurement Notes

Verify the specific datasheet revision and part number suffix when ordering, as configurations may vary. Confirm thermal interface requirements and mounting torque specifications against your mechanical design. Ensure the cooling solution provides at least 1500 LFM airflow to maintain junction temperatures within the specified -40°C to +150°C range. Validate that the input power supplies match the required 24VDC or 15VDC ranges without simultaneous connection.

Selection Notes

Select this assembly for applications requiring high efficiency and integrated protection in a compact form factor. It is suitable for designs needing built-in current sensing and fault isolation. Consider the weight of 21 lb and the requirement for forced air cooling when designing the enclosure. Ensure the control logic can handle the open-collector error outputs and analog feedback signals provided by the gate drive board.

Part Context

This component belongs to the Powerex POW-R-PAK family of configurable power assemblies. These modules are designed to simplify the integration of high-power semiconductor devices by combining the IGBT chips, gate drive electronics, and passive components into a single unit. This approach reduces parasitic inductance and simplifies the overall system architecture compared to discrete component designs.

Replacement Considerations

Direct replacements must match the 100A/1200V rating and three-phase configuration. Verify that alternative modules support similar switching frequencies and include comparable integrated protection features. Mechanical dimensions and mounting hole patterns should be checked for compatibility with existing heatsinks and enclosures.
