3SMBJ5927B-TP

Single Zener Diodes Overview

The 3SMBJ5927B-TP is a surface mount silicon Zener diode manufactured by Micro Commercial Components (MCC). It provides voltage regulation with a nominal Zener voltage of 12 V and a power dissipation rating of 3.0 W. The device features a ±5% voltage tolerance and operates within a junction temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 6.5 Ω at a test current of 31.2 mA, a maximum reverse leakage current of 1 µA at 9.1 V, and a forward voltage of 1.5 V at 200 mA. It utilizes the DO-214AA (SMB) package.

Single Zener Diodes Feature Summary

• Glass passivated junction for enhanced reliability
• Halogen-free "Green" device compliant with environmental standards
• Lead-free finish and RoHS compliant construction
• Epoxy material meets UL 94 V-0 flammability rating

Single Zener Diodes Applications

• Voltage regulation in high-density circuit boards
• Low profile mounting applications
• Surge stress protection circuits

Single Zener Diodes Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase from Micro Commercial Components Corp. to avoid counterfeit parts. Confirm that the ordering suffix "-TP" indicates tape and reel packaging containing 3000 pieces per reel. Ensure compliance with specific project requirements regarding halogen-free status and RoHS directives before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 12 V reference with 3.0 W power handling capability in an SMB package. Consider the thermal resistance values of 226°C/W junction-to-ambient and 25°C/W junction-to-lead for heat dissipation planning. Verify that the operating environment stays within the specified -65°C to +150°C temperature range.

Single Zener Diodes Part Context

This part belongs to the 3SMBJ5918B through 3SMBJ5956B series of 3.0 Watt Surface Mount Silicon Zener Diodes. The series covers a voltage range from 5.1 V to 200 V. The 3SMBJ5927B-TP specifically corresponds to the 12 V variant within this lineup, sharing common mechanical and electrical characteristics with other members of the family.

Single Zener Diodes Replacement Considerations

Equivalent devices include the SMBJ5927B series which offers identical electrical characteristics but may differ in power rating or package style depending on the manufacturer. Cross-referencing should verify the 3.0 W rating and DO-214AA footprint compatibility.
