Single Diodes Procurement Notes

Verify the specific ordering suffix matches the required packaging quantity, as the -18 designation indicates tape and reel configuration. Confirm that the component meets the necessary AEC-Q101 requirements if automotive qualification is needed, noting that standard E3 versions are commercial grade while HE3 variants offer automotive compliance. Ensure the datasheet revision aligns with current manufacturing specifications before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a single diode with a 100 V reverse voltage rating is required in a compact SMD form factor. Consider the thermal resistance and power dissipation limits relative to ambient operating conditions. Evaluate the reverse recovery time and capacitance against the specific frequency requirements of the target circuit to ensure adequate switching speed and signal integrity.

Single Diodes Part Context

This part belongs to the BAV19W/BAV20W/BAV21W series of small signal switching diodes manufactured by Vishay Semiconductors. The series shares common mechanical dimensions and packaging options, differentiated primarily by their reverse voltage ratings. The BAV19W specifically targets applications requiring 100 V blocking capability within the SOD-123 footprint.

Single Diodes Replacement Considerations

Cross-reference with BAV20W or BAV21W if higher reverse voltage ratings are acceptable. Verify pinout compatibility and thermal characteristics when substituting with other SOD-123 switching diodes from different manufacturers.
