SMBJ5358BE3/TR13

Single Zener Diodes Overview

The SMBJ5358BE3/TR13 is a surface mount 5.0 Watt Zener diode manufactured by Microchip Technology, equivalent to the JEDEC registered 1N5358B series. It features a gull-wing lead frame in a DO-215AA package with RoHS compliant matte-tin plating. The device provides a nominal Zener voltage of 22 V with a ±5% tolerance (suffix B). Key electrical characteristics include a maximum dynamic impedance of 3.5 Ohms and a maximum reverse current of 0.5 µA at 17.3 V. It operates within a junction temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

• Surface mount design compatible with high-density and low-profile mounting requirements
• Equivalent electrical performance to the JEDEC registered 1N5333 through 1N5388B axial-leaded series
• RoHS compliant matte-tin finish available for soldering per MIL-STD-750 standards
• Moisture classification Level 1 requiring no dry pack storage

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Protection against high surge stresses in electronic circuits
• Replacement for axial-leaded components in surface mount PCB layouts

Single Zener Diodes Procurement Notes

Verify component authenticity and datasheet revision status prior to procurement. Confirm that the specific ordering suffix matches the required tolerance and packaging configuration. Ensure compliance with relevant environmental directives applicable to your region. Cross-reference the manufacturer's part nomenclature to validate the breakdown voltage tolerance and terminal plating specifications.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and 22-volt regulation are required in a surface mount form factor. The ±5% tolerance offers standard precision suitable for general-purpose applications. Consider the thermal resistance values and derating curves if operating near maximum temperature limits. Verify footprint compatibility with the DO-215AA gull-wing package dimensions during the PCB layout phase.

Single Zener Diodes Part Context

This device belongs to the SMBG5333B through SMBG5388B series of surface mount silicon Zener diodes. It serves as the direct surface-mount equivalent to the traditional 1N5333B through 1N5388B axial-leaded parts. The series covers a wide voltage selection from 3.3 V to 200 V, allowing designers to maintain consistent mechanical profiles across different voltage requirements while utilizing identical testing and electrical characteristics.

Single Zener Diodes Replacement Considerations

Direct replacement is available in the form of the axial-leaded 1N5358B, which shares identical electrical characteristics. Designers must account for the physical package difference between the DO-215AA gull-wing and the T-18 axial leaded format. Ensure the PCB footprint supports the specific terminal geometry of the SMBG series.
