SMBG5919AE3/TR13

Single Zener Diodes Overview

The SMBG5919AE3/TR13 is a Zener voltage regulator diode manufactured by Microsemi. It utilizes the SMBG surface-mount package, specifically the DO-215AA form factor with gull-wing leads. The device provides a standard Zener voltage of 19V and supports a maximum power dissipation of 2.0W. It operates within a junction temperature range of -65°C to +150°C. The component is RoHS compliant and features a moisture sensitivity level of 1.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation in a compact surface-mount configuration
• Features gull-wing design for visible solder connections and high-density mounting
• Offers higher power rating compared to equivalent axial-leaded JEDEC series

Single Zener Diodes Applications

• Voltage regulation in low-profile electronic assemblies
• High-density circuit board mounting applications
• General-purpose Zener diode protection circuits

Single Zener Diodes Procurement Notes

Verify current availability status as this specific part number may be discontinued or subject to limited supply conditions. Confirm that the required packaging format matches the TR13 designation. Ensure compatibility with RoHS standards if applicable to the target assembly. Cross-reference with official Microsemi documentation for any recent product change notifications or lifecycle updates before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 2.0W surface-mount Zener diode is required for voltage regulation. The DO-215AA package is suitable for applications needing gull-wing termination for visual inspection of solder joints. Consider thermal management requirements given the 2.0W power rating. Verify that the 19V Zener voltage aligns with the circuit design specifications and operating temperature range.

Single Zener Diodes Part Context

This component belongs to the SMBG series of Zener diodes from Microsemi. The series offers surface-mount equivalents to the traditional axial-leaded 1N5913 through 1N5956 JEDEC registered numbers. The SMBG variant specifically distinguishes itself with a 2.0W power rating, which is higher than the 1.5W rating of the axial counterparts, enabled by the lower thermal resistance of the surface-mount packaging.
