Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details and compliance status. The datasheet indicates that the E3 suffix denotes RoHS compliance and commercial grade material categorization. Confirm lead length specifications if thermal resistance calculations are required for the application. Ensure the component meets the intended environmental operating conditions before integration.

Selection Notes

Select this component for designs requiring fast recovery times and low leakage in through-hole configurations. The 50 V rating suits low-voltage rectification tasks where high surge capability is beneficial. Consider the thermal resistance and derating curves when determining heat dissipation requirements. Validate suitability for the specific frequency and current loads of the target circuit.

Part Context

This part belongs to the Vishay 1N4933GP series, which includes variants with different reverse voltage ratings such as 100 V, 200 V, 400 V, and 600 V. All members share the same physical package and general electrical characteristics except for the voltage ratings. The GP designation indicates the glass passivated junction technology used across the family.

Replacement Considerations

Direct substitutes within the same Vishay series include 1N4934GP, 1N4935GP, 1N4936GP, and 1N4937GP, provided their higher voltage ratings do not conflict with design constraints. Verify pinout compatibility and package dimensions when considering alternatives from other manufacturers.
