Single Diodes Procurement Notes

Verify the specific suffix PBF for lead-free compliance against current datasheets, as manufacturing sites may vary. Confirm availability status, as this part number is listed as discontinued in multiple distributor records. Ensure the ordering quantity matches the tube packaging format if applicable. Cross-reference the exact electrical parameters with the official Vishay datasheet before finalizing procurement to avoid mismatches with updated specifications.

Single Diodes Selection Notes

Select this component when a standard recovery time is sufficient for the application frequency, offering a balance between cost and performance. The 1.2 kV rating provides adequate margin for high-voltage AC lines. Consider the TO-247AC package for efficient heat dissipation in high-current scenarios. Evaluate the 1.1 V forward voltage drop impact on overall system efficiency compared to faster recovery alternatives if switching losses are critical.

Single Diodes Part Context

This rectifier belongs to Vishay's high-power diode portfolio, designed for robust industrial applications. The TO-247AC package is standard for medium-to-high current discrete semiconductors, facilitating direct heatsink mounting. The product line emphasizes reliability under harsh electrical conditions, serving as a fundamental building block for power electronics where standard recovery characteristics meet operational requirements.

Single Diodes Replacement Considerations

Direct substitutes include other Vishay 40 A, 1200 V standard recovery rectifiers in TO-247 packages, such as the VS-40EPF12 series, though recovery times differ. Verify pinout compatibility and thermal resistance values when replacing with components from other manufacturers like Littelfuse or ON Semiconductor.
