SMBG4738E3/TR13

Single Zener Diodes Overview

The SMBG4738E3/TR13 is a single silicon Zener diode manufactured by Microsemi Corporation. It features a nominal Zener voltage of 8.2V with a tolerance of ±10%. The component is rated for a maximum power dissipation of 2W and operates within a temperature range of -65°C to +150°C. It utilizes the DO-215AA (SMBG) surface-mount package, which supports gull-wing termination designs. The device complies with RoHS standards and carries the e3 suffix indicating lead-free construction.

Single Zener Diodes Feature Summary

• Provides voltage regulation in surface-mount applications
• Features low thermal resistance for efficient heat dissipation
• Compatible with JEDEC registered axial equivalents

Single Zener Diodes Applications

• Voltage regulation circuits
• Protection against overvoltage transients
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration to ensure compatibility with required tolerance levels and packaging formats. Confirm that the DO-215AA footprint matches the target PCB design. Check for RoHS compliance documentation if environmental regulations apply to the final assembly process.

Single Zener Diodes Selection Notes

Select this component when a 2W surface-mount Zener diode is required for space-constrained designs. Consider the ±10% tolerance for general regulation tasks. Ensure the operating temperature range meets the environmental conditions of the intended application.

Single Zener Diodes Part Context

This part belongs to the SMBG series of 2.0 Watt Zener diodes from Microsemi. The series offers a wide selection of voltages from 3.3 to 100 volts. These components are designed as surface-mount equivalents to traditional axial-leaded diodes, providing identical electrical characteristics with higher power ratings.

Single Zener Diodes Replacement Considerations

The SMBG4738E3 is electrically equivalent to the JEDEC registered 1N4764A axial diode, except for the increased 2.0 W rating. Verify pinout compatibility when substituting into existing axial-leaded designs.
