BAV19W-TP

Overview

The BAV19W-TP is a small signal switching diode manufactured by Micro Commercial Components (MCC). It features a single silicon epitaxial planar configuration housed in an SOD-123 surface-mount package. Key electrical specifications include a maximum repetitive peak reverse voltage of 100 V and an average forward rectified current of 200 mA. The device exhibits a typical forward voltage of 1.25 V at 200 mA and a reverse leakage current of 100 nA at 100 V. It operates within a junction temperature range of -55°C to +150°C with a power dissipation rating of 410 mW.

Feature Summary

• Utilizes silicon epitaxial planar technology for reliable general-purpose switching performance.
• Encapsulated in halogen-free epoxy resin meeting UL 94 V-0 flammability ratings.
• Designed for high-temperature operation with a wide junction temperature range.

Applications

• General purpose signal switching circuits
• High-speed digital logic interfaces
• Protection against voltage transients

Procurement Notes

Verify the specific ordering suffix to confirm compliance requirements, as the standard TP designation indicates lead-free finish and RoHS compliance. Confirm the package type matches the required footprint, as variations exist within the series. Ensure the selected variant meets the necessary automotive or industrial qualification standards if applicable to the target application environment.

Selection Notes

Select this component when a compact surface-mount solution is required for low-current switching applications. The SOD-123 package offers space efficiency compared to through-hole alternatives. Consider the 100 V reverse voltage rating to ensure adequate margin for the specific circuit operating conditions. Verify thermal management needs based on the 410 mW power dissipation limit.

Part Context

This part belongs to the BAV19W series of small signal diodes from Micro Commercial Components. The series includes variants with different voltage ratings and packaging options, such as the BAV21W for higher voltage applications. These components are widely used in consumer electronics and industrial equipment requiring reliable, low-cost switching elements.

Replacement Considerations

Direct substitutes may include other 100V, 200mA SOD-123 small signal diodes from manufacturers like Diodes Incorporated or Nexperia, provided pinout and electrical characteristics align. Verify that alternative parts meet the same RoHS and halogen-free requirements.
