Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure compatibility with required packaging or tape-and-reel specifications. Confirm that the component status remains active for production use. Cross-reference the datasheet revision date to ensure all electrical limits and thermal characteristics align with current design requirements before finalizing procurement orders.

Single Diodes Selection Notes

Select this component for applications requiring fast switching capabilities within a standard axial leaded glass package. Ensure the circuit operates within the specified continuous reverse voltage of 150 V and forward current limits. Consider the thermal resistance values when designing heat dissipation strategies for ambient temperatures exceeding standard conditions.

Single Diodes Part Context

The BAV20 belongs to a series of general purpose diodes manufactured by Nexperia. It shares the same physical package and manufacturing technology as the BAV21, differing primarily in voltage ratings. This family of components is designed for robust performance in industrial and consumer electronics environments where hermetic sealing and fast switching are critical.

Single Diodes Replacement Considerations

The BAV21 is a direct functional substitute within the same package, offering higher voltage ratings of 250 V repetitive peak reverse voltage and 200 V continuous reverse voltage. Verify that the lower voltage rating of the BAV20 meets the specific circuit requirements if substituting from a higher-rated variant.

Single Diodes FAQ

What is the maximum non-repetitive peak forward current?

The maximum non-repetitive peak forward current is 9 A for a pulse duration of 1 μs.

How does the junction temperature affect reverse current?

The reverse current increases significantly with junction temperature, reaching a maximum of 100 μA at Tj = 150 °C.
