SMBJ5915C/TR13

Single Zener Diodes Overview

The SMBJ5915C/TR13 is a surface mount 2.0 W Zener diode from the SMBJ59 family, equivalent to JEDEC registered 1N5918–1N5924 series but with a higher power rating enabled by lower thermal resistance. It operates within a Zener voltage range of 5.1 V to 9.1 V and features standard tolerances including ±2%. Packaged in the DO-214AA (SMB) J-bend configuration for high-density mounting, it offers Level 1 moisture classification without requiring dry packing.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Resistant to electrostatic discharge per MIL-STD-750 method 1020
• Capable of withstanding high surge stresses with minimal voltage variation versus current

Single Zener Diodes Applications

• Voltage regulation in high-density circuit designs
• Protection against transient voltage spikes
• Reference voltage sources in low-profile electronic assemblies

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized Microchip channels or certified distributors. Confirm RoHS compliance status via the specific ordering suffix and check for recent product discontinuance notifications. Ensure storage conditions meet IPC/JEDEC standards despite Level 1 moisture classification.

Single Zener Diodes Selection Notes

Select this component when a 2.0 W power rating is required in a compact SMB package. The J-bend design supports greater PC board mounting density compared to axial equivalents. Consider thermal derating requirements if operating above ambient temperatures or without adequate heat sinking on FR4 substrates.

Single Zener Diodes Part Context

This device belongs to the SMBJ59 series of silicon Zener diodes manufactured by Microchip Technology. The series bridges the gap between traditional axial-lead components and modern surface-mount requirements, offering identical electrical characteristics to the 1N5918–1N5924 series while delivering a 30% higher power rating due to improved thermal performance.

Single Zener Diodes Replacement Considerations

Direct replacements include other SMBJ59 series variants with matching Zener voltages and tolerances. Axial equivalents such as the 1N5918–1N5924 series are electrically compatible but differ in power handling and physical footprint.
