C430PB

Scrs Overview

The C430PB is a Phase Control Silicon Controlled Rectifier (SCR) manufactured by Powerex Inc. It features a disk button package with four terminals and a ceramic metal-sealed cofired body. The device supports an average on-state current of 680 Amperes and a maximum RMS on-state current of 1070 Amperes. It offers a repetitive peak reverse voltage range of 500 to 1300 Volts, with a specific rating of 1200 V documented in parameter lists. Key electrical characteristics include a circuit commutated turn-off time of 125 µs, a critical rate of rise of off-state voltage of 200 V/µs, and a non-repetitive peak on-state current of 8000 A. The component operates within a temperature range of -40 °C to 125 °C.

Scrs Feature Summary

• High-power phase control capability for industrial applications
• Robust ceramic metal-sealed disk button construction
• Fast circuit commutated turn-off performance

Scrs Applications

• Industrial motor drives
• Power supply systems
• Phase-controlled rectification circuits

Scrs Procurement Notes

Verify the specific voltage rating required, as datasheets indicate a range from 500 to 1300 Volts. Confirm the gate trigger specifications match the driving circuit requirements. Ensure the thermal management system supports the specified operating temperature range up to 125 °C. Check for any specific packaging or handling instructions due to the disk button form factor.

Scrs Selection Notes

Select this component based on the required average current of 680 A and the necessary blocking voltage within the 500-1300 V range. Consider the 125 µs turn-off time for high-frequency commutation needs. Evaluate the physical dimensions of the SC-4 disk button package for mounting compatibility. Compare against similar Powerex SCR models if specific voltage or current ratings differ slightly from project requirements.

Scrs Part Context

The C430PB belongs to Powerex's line of phase control SCRs, designed for high-current industrial power conversion. It is part of a family that includes variants like the C430EX555, which shares similar structural characteristics but may differ in specific current or voltage ratings. These devices are typically used in heavy-duty applications requiring reliable high-power switching.

Scrs Replacement Considerations

Check for direct substitutes within the Powerex C430 series, such as the C430EX555, noting differences in average current ratings. Verify pinout compatibility and thermal resistance values when considering cross-manufacturer replacements. Ensure any alternative device meets or exceeds the 125 µs turn-off time and 200 V/µs dv/dt rating.
