BAV19TR

Single Diodes Overview

The BAV19TR is a small signal switching diode from onsemi, packaged in the DO-35 through-hole format. It is a single-element silicon rectifier designed for general-purpose applications. Key electrical specifications include a maximum repetitive reverse voltage of 120V and an average rectified forward current of 200mA. The device exhibits a typical forward voltage drop of 1.25V at rated current and features a fast recovery time of 50ns. It supports a peak forward surge current of 4A, making it suitable for high-speed switching tasks in low-power circuits.

Single Diodes Feature Summary

• High-voltage capability with 120V reverse voltage rating
• Fast switching performance with 50ns recovery time
• Compact DO-35 axial leaded package for through-hole mounting

Single Diodes Applications

• General-purpose signal switching
• Clamping and protection circuits

Single Diodes Procurement Notes

Verify the component marking and date code against official onsemi documentation to ensure authenticity. Confirm that the DO-35 package dimensions match your PCB footprint requirements. Check for any specific handling instructions regarding electrostatic discharge during assembly. Ensure the supplier provides traceability data consistent with industry standards for electronic components.

Single Diodes Selection Notes

Select this component when a fast-recovery diode with moderate voltage ratings is required in a through-hole configuration. The 120V rating suits applications with higher transient voltages compared to standard 50V diodes. Consider the 200mA current limit for load requirements. The DO-35 package offers robust mechanical stability for manual or automated insertion processes in legacy or industrial designs.

Single Diodes Part Context

The BAV19TR belongs to onsemi's portfolio of discrete semiconductor devices, specifically within the small-signal diode category. It utilizes silicon planar technology optimized for reliability and performance. This part is commonly used in conjunction with other passive and active components to manage signal integrity and power flow in compact electronic assemblies.

Single Diodes Replacement Considerations

Compatible substitutes include the BAV19 from other manufacturers such as Nexperia or Vishay, provided they meet the same 120V, 200mA, and DO-35 package specifications. Verify pinout compatibility and thermal characteristics before substitution.
