Procurement Notes
Verify the specific ordering suffix against official documentation to confirm compliance status and packaging details. Confirm RoHS compliance and material categorization requirements prior to procurement. Ensure design suitability as this component is designated not for new designs. Validate thermal resistance and lead length specifications for your specific mounting configuration.
Selection Notes
Select this component for applications requiring fast recovery characteristics and low leakage current. The DO-41 package provides through-hole mounting compatibility. Consider the 175 °C maximum junction temperature for high-temperature environments. Verify that the 600 V reverse voltage rating meets the circuit's peak inverse voltage requirements.
Part Context
This part belongs to the Vishay 1N493xGP series of fast switching plastic rectifiers. The series includes variants with different reverse voltage ratings ranging from 50 V to 600 V. All members share similar electrical characteristics including 1.0 A forward current and 200 ns reverse recovery time. The GP designation indicates the Superectifier structure and glass passivation technology used across the family.
Replacement Considerations
Cross-reference with other manufacturers' 1N4937 equivalents. Verify pinout compatibility and package dimensions (DO-41). Ensure replacement parts meet or exceed the 600 V reverse voltage and 1.0 A forward current ratings. Check if alternative components offer improved thermal performance or lower forward voltage drop.
