C441P

Scrs Overview

The Powerex C441P is a standard recovery thyristor (SCR) designed for high-power industrial applications. It features a 1600V repetitive peak reverse voltage and an 800A maximum RMS on-state current capability within a TO-200AC Press-Pak package. The device supports a gate trigger voltage of up to 5V and a maximum gate trigger current of 300mA. With a non-repetitive peak surge current rating of 11,000A and a circuit turn-off time of 125µs, it provides robust performance in demanding environments operating between -45°C and 125°C.

• Standard recovery characteristics suitable for general-purpose rectification

Scrs Applications

• Industrial motor drives and variable frequency drives
• High-power DC power supplies and rectifiers
• Welding equipment power stages
• Static power switching systems

Scrs Procurement Notes

Verify the specific suffix designation against official datasheets, as variations such as C441PM may indicate different voltage or current ratings. Confirm package compatibility with heatsinking requirements before procurement. Ensure ordering documentation matches the exact part number to avoid functional mismatches in high-current circuits.

Scrs Selection Notes

Select this component based on its 1600V blocking capability and 800A RMS current rating. Evaluate the 125µs turn-off time against the system's switching frequency requirements. Consider the TO-200AC form factor for mechanical integration and thermal dissipation needs in high-power density designs.

Scrs Part Context

This device belongs to the Powerex DSC series of silicon controlled rectifiers. It utilizes a press-pak technology that integrates the semiconductor die directly into a cooling structure, offering superior thermal conductivity compared to traditional leaded packages. This design is typical for heavy-duty industrial power electronics requiring reliable operation under extreme electrical stress.

Scrs Replacement Considerations

Direct cross-compatibility should be verified using official substitution guides. Alternative devices must match the 1600V voltage class, TO-200AC footprint, and comparable current ratings. Differences in gate charge or turn-off times may require circuit adjustments.
