CD630815B

SCRs - Modules Overview

The Powerex CD630815B is a Dual SCR Isolated POW-R-BLOK module rated for 800 Volts and 150 Amperes. It features electrically isolated heatsinking with a DBC Alumina insulator and glass passivated chips. The device supports repetitive peak forward and reverse blocking voltages up to 1800 Volts across the series, with specific ratings of 800V for this variant. Key electrical parameters include a peak on-state voltage of 1.6 V at 500 A, gate trigger current of 150 mA, and holding current of 150 mA. Thermal resistance from junction to case is 0.085 °C/W per module. Operating temperature ranges from -40°C to +125°C.

SCRs - Modules Procurement Notes

Verify the complete nine-digit part number against the manufacturer's ordering table to ensure correct voltage and current ratings. Confirm that the specific suffix matches the required blocking voltage level within the CD63__15B family. Check revision dates on datasheets as specifications are subject to change without notice. Ensure mounting torque specifications are strictly followed during installation to maintain reliability.

SCRs - Modules Selection Notes

Select based on required blocking voltage from the available options (800V to 1800V) while maintaining the 150A current rating. Consider the thermal resistance values when designing heatsink solutions for continuous operation. Verify isolation voltage requirements against the 3600 Vrms specification. Ensure gate drive circuits can supply the necessary trigger current and voltage levels specified in the electrical characteristics.

SCRs - Modules Part Context

This component belongs to the CD63__15B series of Dual SCR Isolated POW-R-BLOK modules manufactured by Powerex Inc. The series offers various voltage ratings from 800V to 1800V, all sharing the same 150A current capacity and physical outline dimensions. These modules are designed for phase control applications requiring isolated packaging for easy mounting on common heatsinks.

SCRs - Modules Replacement Considerations

Direct replacements must match the 150A current rating, 800V blocking voltage, and identical mechanical footprint. Verify that alternative dual SCR modules provide comparable thermal resistance and isolation voltage ratings. Ensure gate trigger characteristics are compatible with existing drive circuitry.
