SMBG5359A/TR13

Single Zener Diodes Overview

The SMBG5359A/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 24 V with a ±10% tolerance, indicated by the 'A' suffix. The device operates in a DO-215AA (SMBG) gull-wing package and is rated for a maximum power dissipation of 5.0 W at a lead temperature below 25 °C. Electrical characteristics include a test current (IZT) of 50 mA, a maximum dynamic impedance (ZZ) of 3.5 Ohms, and a maximum reverse current (IR) of 0.5 µA tested at 17.3 V.

Single Zener Diodes Feature Summary

• Surface mount equivalent to JEDEC registered 1N5359B series with identical electrical characteristics.
• Gull-wing design in the DO-215AA package allows for visible solder connections.
• Plastic encapsulated body meets UL94V-0 standards with Level 1 moisture classification.
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020.

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 prior to integration. Confirm that the specific ordering suffix matches required plating options, as the series offers both Sn/Pb and RoHS compliant matte-tin finishes. Ensure thermal management aligns with the specified derating curves for the intended PCB footprint.

Single Zener Diodes Selection Notes

Select this component when a 24 V reference or clamp is required in a surface mount topology. The DO-215AA package is suitable for designs prioritizing visible solder joints. Verify that the ±10% voltage tolerance meets circuit requirements, as tighter tolerances are available in other part numbers within the same series.

Single Zener Diodes Part Context

This device belongs to the SMBG5333B through SMBG5388B family of 5-watt Zener diodes. These components serve as direct surface-mount replacements for the axial-leaded 1N5333 through 1N5388B series. The SMBG variant specifically utilizes a gull-wing lead frame configuration distinct from the J-bend SMBJ package.

Single Zener Diodes Replacement Considerations

Direct equivalents include the axial-leaded 1N5359B and the J-bend surface mount SMBJ5359B. When substituting, verify that the replacement package supports the required thermal dissipation and mechanical footprint constraints.
