SMBJ5380B-TP

Single Zener Diodes Overview

The SMBJ5380B-TP is a 5.0 W surface mount silicon Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 120 V with a ±5% tolerance, housed in the low-profile DO-214AA (SMB) package. The device operates within a junction temperature range of -55°C to +150°C and exhibits a maximum dynamic impedance of 170 Ω at a test current of 10 mA. It supports a maximum forward voltage of 1.2 V at 1.0 mA and includes lead-free finish compliant with RoHS standards.

Single Zener Diodes Feature Summary

• Low profile package design for accurate surface mounting placement
• Halogen-free green device construction meeting UL 94 V-0 flammability rating
• Moisture sensitivity level 1 classification for standard handling

Single Zener Diodes Applications

• Voltage regulation circuits requiring 120 V reference
• Surge protection applications utilizing peak pulse power capabilities
• General purpose clamping in electronic assemblies

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized MCC distributors or direct purchase to ensure traceability and compliance with quality standards. Confirm that ordering suffixes match specific packaging requirements such as tape and reel quantities. Review datasheet specifications regarding derating curves and thermal resistance values before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 120 V Zener voltage with 5 W steady-state power dissipation is required in a surface mount configuration. Ensure the application environment remains within the specified -55°C to +150°C operating junction temperature range. Consider the 170 Ω dynamic impedance characteristics for circuit stability requirements.

Single Zener Diodes Part Context

This part belongs to the SMBJ5338B through SMBJ5388B series of 5.0 W surface mount silicon Zener diodes. The series covers a voltage range from 5.1 V to 200 V, all sharing the same DO-214AA package footprint and thermal characteristics. The SMBJ5380B-TP specifically addresses higher voltage regulation needs within this standardized product family.

Single Zener Diodes Replacement Considerations

Substitute only with verified equivalent parts offering identical 120 V nominal voltage, 5 W power rating, and DO-214AA package dimensions. Cross-referencing must confirm matching electrical parameters including dynamic impedance and leakage current limits.
