SMBG5380CE3/TR13

Single Zener Diodes Overview

The SMBG5380CE3/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 120 V with a ±2% tolerance. The device operates in a DO-215AA (SMBG) gull-wing package and supports a maximum power dissipation of 5.0 W at a lead temperature below 25 °C. Electrical characteristics include a test current of 10 mA, a maximum dynamic impedance of 170 Ohms, and a maximum reverse leakage current of 0.5 µA tested at 86.4 V.

Single Zener Diodes Feature Summary

• Surface mount equivalent to JEDEC registered 1N5333 thru 1N5388 series
• 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
• High-density and low-profile mounting applications
• Protection against high surge stresses

Single Zener Diodes Procurement Notes

Verify component authenticity and datasheet revision status before integration. Confirm that the RoHS compliance suffix matches project requirements. Check for any product change notifications or discontinuance alerts issued by the manufacturer. Ensure storage conditions adhere to the specified moisture sensitivity level to prevent package damage during soldering processes.

Single Zener Diodes Selection Notes

Select this component when a precise 120 V reference is required in a surface mount design. The ±2% tolerance offers tighter regulation than standard 5% or 10% variants. Verify thermal management capabilities, as the 5 W rating depends on adequate heat sinking and PCB copper area. Ensure the operating environment remains within the -65 °C to +150 °C junction temperature range.

Single Zener Diodes Part Context

This part belongs to the SMBG5333B–SMBG5388B family of 5-watt Zener diodes. These devices are designed as surface mount equivalents to the axial-leaded 1N5333–1N5388 series, sharing identical electrical characteristics. The series covers a wide voltage selection from 3.3 V to 200 V, utilizing different suffix letters to denote specific breakdown voltage tolerances.

Single Zener Diodes Replacement Considerations

Direct replacements include other SMBG5380 variants with matching tolerance suffixes, such as SMBG5380B or SMBG5380A, provided the voltage tolerance aligns with circuit requirements. Equivalent axial-leaded parts like 1N5380 can be used if board space permits.
