3SMBJ5921B-TP

Single Zener Diodes Overview

The 3SMBJ5921B-TP is a unidirectional silicon Zener diode manufactured by MCC in the SMB (DO-214AA) surface-mount package. It features a nominal Zener voltage of 6.8 V with a ±5% tolerance and a maximum power dissipation of 3.0 W. The device includes a glass-passivated junction, operates within a temperature range of -65°C to +150°C, and complies with RoHS standards.

Single Zener Diodes Feature Summary

• Glass-passivated junction for enhanced reliability
• Halogen-free 'Green' device compliant with environmental standards
• Lead-free finish meeting UL 94 V-0 flammability rating

Single Zener Diodes Applications

• General-purpose voltage regulation circuits
• Transient voltage suppression applications
• Protection of sensitive electronic components from overvoltage events

Single Zener Diodes Procurement Notes

Verify authenticity through authorized distributors or direct purchase from MCC to avoid counterfeit parts. Confirm the specific suffix '-TP' indicates tape and reel packaging containing 3,000 pieces per reel. Ensure the component meets required RoHS compliance and halogen-free specifications for your manufacturing process.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V Zener reference or clamp is needed in a compact SMB footprint. Consider the 3.0 W power rating and thermal resistance values for heat dissipation requirements. Verify that the operating temperature range aligns with the intended application environment.

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 5.1V to 200V, offering various voltage options in the same DO-214AA package form factor for design flexibility.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same MCC series include 3SMBJ5920B-TP (6.2V) and 3SMBJ5922B-TP (7.5V). Cross-manufacturer replacements must match the 6.8V nominal voltage, 3W power rating, and DO-214AA package dimensions.
