SMBG5349BE3/TR13

Single Zener Diodes Overview

The SMBG5349BE3/TR13 is a surface mount silicon Zener diode from the SMBG5333B through SMBG5388B series, manufactured by Microchip Technology. It provides a nominal Zener voltage of 12 V with a tolerance of ±5%. The device operates in a DO-215AA gull-wing package and features a maximum power dissipation of 5.0 W at a lead temperature below 25 °C. Electrical characteristics include a test current (IZT) of 100 mA, a maximum dynamic impedance (ZZT) of 2.5 Ohms, and a maximum reverse current (IR) of 2.0 µA tested at 8.6 V. The component supports an operating junction and storage temperature range from -65 °C to +150 °C.

Single Zener Diodes Feature Summary

• Surface mount equivalent to JEDEC registered 1N5333 thru 1N5388 series for high-density mounting.
• RoHS compliant matte-tin finish available alongside Sn/Pb plating options.
• Moisture classification Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack.
• Non-sensitive to ESD per MIL-STD-750 method 1020.

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges.
• High surge stress withstand applications.
• Low-profile circuit board mounting.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'e3' confirms RoHS compliance and 'TR13' indicates tape and reel packaging per EIA-481-1-A standards. Confirm the manufacturer designation as Microchip Technology or its predecessor entity Microsemi Corporation depending on production date. Ensure the part number matches the exact electrical parameters required for the design, specifically the 12 V breakdown voltage and ±5% tolerance.

Single Zener Diodes Selection Notes

Select this component when a 5-watt surface mount Zener diode with gull-wing leads is required. The DO-215AA package allows for visible solder connections compared to standard J-bend packages. Consider the thermal resistance values of 25 °C/W junction-to-lead and 90 °C/W junction-to-ambient for heat sinking calculations. Verify that the application does not require moisture sensitivity levels higher than Level 1.

Single Zener Diodes Part Context

This device belongs to the SMBG5333B through SMBG5388B series of surface mount 5.0 watt Zener diodes. The series offers a selection of voltages from 3.3 to 200 volts with various tolerances identified by suffix letters. These parts are electrically equivalent to the JEDEC registered 1N5333 through 1N5388 axial-leaded series but utilize the SMBG gull-wing package format.
