Overview
The Powerex PD411811 is a POW-R-BLOK dual diode isolated module rated for 1100 Amperes and up to 2600 Volts. It features electrically isolated heatsinking, compression bonded elements, and a metal baseplate with low thermal impedance. The module supports repetitive peak reverse blocking voltages up to 2600 V and offers an isolation voltage of 4000 Vrms at 25°C. Operating temperatures range from -40 to +150 °C, with typical weight of 5.33 kg.
Feature Summary
- Electrically isolated heatsinking design
- Compression bonded elements
- Metal baseplate construction
- Low thermal impedance for improved current capability
Applications
- Bridge circuits
- AC & DC motor drives
- Battery supplies
- Power supplies
- Large IGBT circuit front ends
Procurement Notes
Verify the specific voltage rating suffix (e.g., 18 for 1800V) when ordering, as the PD41__11 series covers multiple voltage options up to 2600V. Confirm UL recognition status (E78240) and mounting torque specifications for M6 and M10 screws during integration planning.
Selection Notes
Select based on required repetitive peak reverse blocking voltage within the 2600V limit. Consider case temperature ratings for RMS current derating curves. Ensure heatsink interface meets the specified thermal resistance requirements for optimal performance.
Part Context
Part of the POW-R-BLOK dual diode isolated module family designed for rectification and isolated packaging. These modules allow easy mounting with other components on a common heatsink without additional insulation parts.
Replacement Considerations
Check equivalent models in the PD41__11 series for different voltage ratings such as PD412411 or PD412611 if higher voltage blocking is needed while maintaining the 1100A current rating.
FAQ
What is the maximum isolation voltage?
The module provides 4000 Vrms isolation at 25°C.
What are the operating temperature limits?
The operating junction temperature ranges from -40 to +150 °C.
How is the module mounted?
It uses M6 mounting screws and M10 terminal screws with specified maximum torques.
