BAV19W-G

Single Diodes Overview

The BAV19W-G is a small signal switching diode manufactured by Taiwan Semiconductor. It features a single silicon junction in an SOD-123 surface-mount package. Key electrical parameters include a maximum repetitive peak reverse voltage of 120 V and a continuous forward current rating of 0.2 A. The device supports a maximum non-repetitive peak forward surge current of 2.5 A. It operates within a temperature range of -55 °C to +150 °C junction temperature, with a specified power dissipation capability suitable for general-purpose high-speed switching applications.

Single Diodes Feature Summary

• Designed for fast switching operations with low leakage current characteristics
• Utilizes plastic encapsulation for reliable surface-mount installation
• Engineered for high efficiency and low power loss during conduction

Single Diodes Applications

• High-speed switching circuits
• General purpose rectification tasks
• Protection against voltage spikes in sensitive electronics

Single Diodes Procurement Notes

Verify the specific manufacturer marking and date code on the component body to confirm authenticity from Taiwan Semiconductor. Ensure the ordering suffix matches the required packaging format, such as reel quantities, as indicated in official distributor catalogs. Cross-reference the Mouser part number or manufacturer catalog ID to prevent substitution errors with similar BAV series devices that may have different voltage ratings.

Single Diodes Selection Notes

Select this component when a single diode configuration with a 120 V reverse voltage rating is required in an SOD-123 footprint. It serves as a direct replacement for standard BAV19 types where Taiwan Semiconductor sourcing is preferred. Consider the 0.2 A average forward current limit and thermal dissipation constraints relative to the PCB layout. Verify compatibility with automated pick-and-place equipment due to the small outline package dimensions.

Single Diodes Part Context

This device belongs to the BAV series of small signal switching diodes produced by Taiwan Semiconductor. The series is characterized by fast switching speeds and robust surge current handling capabilities. The BAV19W-G specifically addresses applications requiring higher reverse voltage tolerance compared to lower-voltage variants like the BAV99, while maintaining a compact form factor for dense circuit board designs.

Single Diodes Replacement Considerations

Direct substitutes include the Vishay BAV19W-HE3-18 and Panjit BAV19W. These alternatives share identical pinouts and comparable electrical specifications, including the 120 V reverse voltage and SOD-123 package type. Verify that the substitute's forward voltage drop and recovery time meet the specific timing requirements of the target application.
