Procurement Notes
Verify the specific part number against the manufacturer's datasheet to confirm electrical ratings and package compatibility before ordering. Ensure that the intended application environment falls within the specified operating temperature range and does not exceed the absolute maximum ratings defined in the official documentation.
Selection Notes
Select this component when a 400 V reverse voltage rating and 1 A continuous forward current are required in a standard SMA footprint. Consider the thermal resistance characteristics and derating curves if the application involves high ambient temperatures or significant surge currents.
Part Context
This component belongs to the CD214A-S1x series of rectifier chip diodes from Bourns Inc. The series offers various voltage ratings ranging from 200 V to 1600 V while maintaining a consistent 1 A forward current capability and DO-214AC package format for standardized surface-mount integration.
Replacement Considerations
Compatible substitutes include other glass passivated rectifiers in the DO-214AC package with matching 400 V reverse voltage and 1 A forward current specifications. Verify pinout compatibility and thermal performance parameters before implementation.
