BAV19W-G3-18

Single Diodes Overview

The BAV19W-G3-18 is a silicon epitaxial planar switching diode from Vishay Semiconductors, housed in an SOD-123 surface-mount package. It features a continuous reverse voltage of 100 V and a repetitive peak reverse voltage of 120 V. The device supports a DC forward current of 250 mA and a surge forward current of 1 A. Electrical characteristics include a maximum forward voltage of 1.25 V at 200 mA, a leakage current of 100 nA at 100 V, and a reverse recovery time of 50 ns. It operates within a temperature range of -55 °C to +150 °C.

Single Diodes Feature Summary

• Utilizes silicon epitaxial planar technology for high-voltage general-purpose applications
• Provides robust surge current capability with a 1 A non-repetitive peak rating
• Designed for efficient thermal management with a junction-to-ambient resistance of 375 K/W

Single Diodes Applications

• General purpose signal switching circuits
• High voltage rectification tasks
• Fast switching logic interfaces

Single Diodes Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm packaging details. The '-18' designation indicates tape and reel packaging containing 10,000 units per 13-inch reel. Ensure compliance with RoHS directives by checking the 'G3' marking which denotes green commercial grade materials. Confirm that the component meets AEC-Q101 qualification requirements if automotive application standards are necessary for your design.

Single Diodes Selection Notes

Select this component when a single diode configuration with a 100 V continuous reverse voltage rating is required. It is suitable for designs needing a compact SOD-123 footprint with a 250 mA continuous forward current capacity. Consider this part for applications requiring a 50 ns reverse recovery time and low capacitance of 1.5 pF. Verify that the operating temperature range of -55 °C to +150 °C aligns with your system's environmental constraints.

Single Diodes Part Context

This component belongs to the BAV19W-G series of small signal switching diodes manufactured by Vishay Semiconductors. The series includes variants with different reverse voltage ratings, such as the BAV20W-G and BAV21W-G. These devices share the same SOD-123 mechanical case and general electrical structure but differ in their maximum voltage specifications. The product line is designed for cost-effective, high-volume surface-mount assembly.

Single Diodes Replacement Considerations

Direct substitutes within the same Vishay family include the BAV20W-G3-18 and BAV21W-G3-18. These parts share identical physical dimensions and packaging but offer higher reverse voltage ratings of 150 V and 200 V respectively. Cross-manufacturer replacements require verification of pinout compatibility and matching electrical parameters.
