SMBG5346BE3/TR13

Single Zener Diodes Overview

The SMBG5346BE3/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 9.1 V with a ±5% tolerance and a maximum power dissipation of 5.0 W at 25°C lead temperature. The device utilizes a DO-215AA gull-wing package (SMBG) and operates within a junction and storage temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 2.0 Ohms and a reverse leakage current of 7.5 µA at 6.6 V.

• Surface mount equivalent to JEDEC registered 1N5333 thru 1N5388 series for high-density mounting
• RoHS compliant matte-tin finish available
• Moisture classification Level 1 per IPC/JEDEC J-STD-020B

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Protection against high surge stresses
• ESD protection non-sensitive per MIL-STD-750 method 1020

Single Zener Diodes Procurement Notes

Verify component authenticity and datasheet revision alignment before procurement. Confirm RoHS compliance status and suffix designations match specific ordering requirements. Check for discontinuance notifications or lifecycle changes directly from the manufacturer. Ensure packaging specifications align with automated assembly needs.

Single Zener Diodes Selection Notes

Select this component when a 9.1 V reference with ±5% tolerance is required in a surface mount configuration. Consider the 5 W power rating and thermal resistance values for heat sinking requirements. Verify compatibility with existing PCB footprints designed for the DO-215AA SMBG package.

Single Zener Diodes Part Context

This part belongs to the SMBG5333B through SMBG5388B series of 5-watt Zener diodes. These devices are designed as surface mount equivalents to the legacy axial-leaded 1N5333 through 1N5388 series, offering identical electrical characteristics while enabling lower-profile circuit board designs.

Single Zener Diodes Replacement Considerations

Direct replacements include other SMBG5346 variants with different tolerances or plating options, such as SMBG5346A or SMBG5346C. Legacy axial equivalents like the 1N5346 may be used if form factor constraints allow.
