Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm that the component meets required environmental standards such as MIL-S-19500 if applicable to the design. Ensure the selected variant matches the exact electrical ratings needed for the target circuit operation.
Selection Notes
Select this component when a 1000V reverse voltage rating and 1.0A continuous current are required. Consider the 500 ns reverse recovery time for high-frequency switching requirements. Evaluate thermal management needs based on the specified operating temperature range and derating curves.
Part Context
This part belongs to the 1N4942GP through 1N4948GP series of glass passivated junction fast switching plastic rectifiers manufactured by Vishay General Semiconductor. The series utilizes a patented glass-plastic encapsulation technique and brazed-lead assembly for enhanced durability.
Replacement Considerations
Consult official datasheets for cross-reference information. Verify that any substitute component matches the 1000V reverse voltage, 1.0A forward current, and DO-204AL package dimensions.
