PS11014

Overview

The PS11014 is a flat-base insulated integrated power module by Mitsubishi Semiconductor, designed for 3-phase AC-to-DC conversion and motor control. It integrates a 3-phase IGBT inverter bridge with dynamic braking capabilities. The device supports an output current capability of 5.0A (rms) at 100% load and 7.5A (rms) for 1-minute overload conditions. Key electrical ratings include a collector-emitter static voltage of 600V and a converter repetitive peak reverse voltage of 800V. Thermal resistance from junction to case ranges from 2.8°C/W to 6.0°C/W depending on the specific component.

Feature Summary

• Integrates a 3-phase IGBT inverter bridge using advanced generation technology alongside a dedicated dynamic braking circuit for regenerative energy management.
• Includes application-specific intelligent power module functions such as high-voltage isolated drive circuits, short-circuit protection, and under/over-voltage locking mechanisms.

• General motor control applications requiring integrated drive and protection
• Systems utilizing dynamic braking for regenerative energy dissipation

Procurement Notes

Verify the specific datasheet version and manufacturer origin, as the model is originally identified with Mitsubishi Semiconductor while distributed by Powerex Inc. Confirm that the flat-base insulated package type matches your thermal management requirements. Ensure the control supply voltages align with the specified 13.5V to 16.5V range for VDH and VDB terminals to guarantee proper operation of the internal drive circuits.

Selection Notes

Select this module for applications requiring a compact solution combining power switching and control logic. The 600V rating suits standard 200V class AC input systems. Consider the thermal resistance values when designing heatsinking, noting the junction temperature limits. The integrated short-circuit and over-temperature protections reduce external component count but require adherence to the recommended pulse-by-pulse reset sequences during fault conditions.

Part Context

This component belongs to the family of Application Specific Intelligent Power Modules (ASIPMs). It combines power semiconductor devices with control ICs to simplify inverter design. The flat-base construction facilitates mounting to heat sinks while providing electrical insulation. These modules are engineered to replace discrete component solutions, offering reduced board space and improved reliability through integrated protection features.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and thermal characteristics if considering alternative ASIPM families from other manufacturers.

FAQ

How does the module handle short-circuit protection?

The module provides instantaneous short-circuit protection that operates on a pulse-by-pulse scheme. Upon detecting a high short-circuit current, it shuts down the gate signal for the affected IGBT and outputs a fault signal via FO1. The protection is designed to prevent destruction rather than regulate load current.

What is the function of the CL terminal?

The CL terminal outputs a current-limit warning signal. It activates when the arm current exceeds a specific limit, indicating an overload condition. This signal is useful for system-level current regulation or overload control, distinct from the immediate shutdown triggered by short-circuit protection.

Can the module be driven directly by a CPU?

Yes, the module features a 5V CMOS/TTL compatible input interface with Schmitt trigger inputs. This allows direct coupling to a CPU without requiring optical or transformer isolation, simplifying the control circuit design.
