• Power supply units requiring robust diode modules

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is limited to existing stock from distributors, and no new production is scheduled. Buyers should verify part authenticity and storage conditions carefully due to the discontinued status. Long-term supply stability cannot be guaranteed, making this suitable only for replacement or non-production purposes.

Selection Notes

Select this module when a 1200 V, 100 A common cathode diode solution is required in a D1 package. Ensure the application supports base-mount cooling methods. Verify that the operating junction temperature remains within the specified -40°C to +150°C range. Consider alternative components if long-term availability is critical, as this part is discontinued.

Part Context

The MSCD100-12 belongs to Microsemi's series of glass-passivated rectifier diode modules. These components are designed for high-reliability applications in power electronics. The D1 package variant provides a standardized footprint for mounting on heatsinks. This specific model represents a standard recovery time device intended for general-purpose rectification tasks in industrial environments.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the product is discontinued, engineers must identify cross-functional equivalents based on matching voltage, current, package type (D1), and electrical characteristics. Verification of pinout compatibility and thermal resistance is essential when selecting a replacement.
