BAV19

Overview

The BAV19 is a high-voltage general-purpose silicon switching diode manufactured by onsemi. It features a single internal configuration housed in the DO-35 axial leaded package. The device is rated for a peak reverse voltage of 120 V and supports a maximum forward current of 200 mA. Key electrical characteristics include a low forward voltage drop and fast switching capabilities, making it suitable for applications requiring reliable rectification and signal processing.

Feature Summary

• High-voltage capability with a 120 V peak reverse voltage rating
• Fast switching performance optimized for general-purpose applications
• Robust surge current handling up to 4 A

Applications

• General-purpose rectification in electronic circuits
• Signal clamping and protection
• Switching applications in consumer electronics

Procurement Notes

Verify the specific ordering suffix (e.g., G) to ensure compliance with RoHS directives and halogen-free requirements. Confirm that the DO-35 package matches your PCB footprint constraints. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a single diode with a 120 V reverse voltage rating is required. It is appropriate for circuits where a 200 mA continuous forward current is sufficient. Consider alternative packages if surface-mount technology is preferred over through-hole mounting.

Part Context

The BAV19 belongs to onsemi’s portfolio of small-signal diodes, which also includes the BAV20 and BAV21 series. These devices share similar structural designs but differ in internal configurations, such as dual common-anode or common-cathode arrangements, whereas the BAV19 is a single unit.

Replacement Considerations

Direct substitutes include the BAV20 and BAV21, though these feature dual-diode configurations rather than a single diode. Verify pinout compatibility and electrical ratings before substituting with generic equivalents from other manufacturers.
