SMBJ5348C/TR13

Single Zener Diodes Overview

The SMBJ5348C/TR13 is a surface mount 5.0 watt Zener diode manufactured by Microchip Technology, housed in the DO-215AA gull-wing package. It provides a nominal breakdown voltage of 11 V with a tight tolerance of +/- 2%, indicated by the 'C' suffix. The device operates within a junction temperature range of -65°C to +150°C and features RoHS compliant matte-tin plating. Electrical characteristics include a maximum dynamic impedance of 2.5 Ohms at a test current of 125 mA, a maximum reverse leakage current of 5.0 µA at 8.0 V, and a maximum regulator current of 8.4 A.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a tight +/- 2% tolerance for sensitive circuit applications.
• Features a gull-wing lead frame design that allows for visible solder connections during assembly.
• Capable of withstanding high surge stresses and non-sensitive to electrostatic discharge.
• Moisture classification is Level 1, eliminating the requirement for dry pack storage.

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High-density and low-profile mounting in surface mount designs
• Protection against high surge stresses in electronic circuits

Single Zener Diodes Procurement Notes

Verify the specific part number suffixes to confirm RoHS compliance and tolerance levels, as the datasheet indicates variations based on these identifiers. Confirm the package type matches the required footprint, noting that this component utilizes the DO-215AA gull-wing configuration rather than standard J-bend packages. Ensure procurement channels provide documentation verifying the matte-tin finish if lead-free specifications are mandatory for the assembly process.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and an 11 V reference voltage are required with high precision. The +/- 2% tolerance makes it suitable for applications demanding strict voltage stability compared to standard 5% or 10% variants. Consider the gull-wing package geometry for assembly visibility requirements and verify thermal management capabilities, as power dissipation ratings depend on the specific mounting conditions and ambient temperature.

Single Zener Diodes Part Context

This component belongs to the SMBG5333B through SMBG5388B series of surface mount silicon Zener diodes. The series offers a selection of voltages ranging from 3.3 to 200 volts. These devices are electrically equivalent to the JEDEC registered 1N5333 through 1N5388 axial-leaded series, providing identical electrical characteristics while offering a compact surface mount alternative for modern PCB layouts.

Single Zener Diodes Replacement Considerations

The SMBJ5348C/TR13 is functionally equivalent to the 1N5348B axial-leaded Zener diode regarding electrical performance. For direct surface mount replacement without reflow profile changes, verify compatibility with other SMBG5348 variants from different manufacturers that utilize the DO-215AA gull-wing package.
