SMBZ5920B-M3/5B

Single Zener Diodes Overview

The SMBZ5920B-M3/5B is a surface-mount power voltage-regulating diode manufactured by Vishay General Semiconductor - Diodes Division. It operates within the SMBZ5919B through SMBZ5945B series and utilizes the SMB (DO-214AA) package. The device provides a nominal Zener voltage of 6.2 V with a tolerance range of 5.89 V to 6.51 V at a test current of 60.5 mA. Maximum steady-state power dissipation reaches 3000 mW at a lead temperature of 75 °C, or 550 mW at an ambient temperature of 25 °C. The component supports an operating junction and storage temperature range from -55 °C to +150 °C.

Single Zener Diodes Feature Summary

• Low profile package suitable for automated placement
• Low Zener impedance and low regulation factor
• Halogen-free, RoHS-compliant commercial grade construction

Single Zener Diodes Applications

• General purpose voltage regulation
• Circuit protection applications

Single Zener Diodes Procurement Notes

Verify compliance requirements before procurement. The M3 suffix indicates halogen-free material composition in addition to RoHS compliance. Confirm that the ordering suffix /5B corresponds to the required delivery mode and base quantity specifications. Ensure technical parameters align with specific application needs prior to purchase.

Single Zener Diodes Selection Notes

Select this component based on the required 6.2 V nominal Zener voltage and the 5.89 V to 6.51 V tolerance range. Evaluate thermal management capabilities, as maximum power dissipation varies significantly between lead-mounted and ambient conditions. Verify that the SMB (DO-214AA) package dimensions fit the target PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the SMBZ5919B through SMBZ5945B series of surface-mount power voltage-regulating diodes. All devices in this series share identical mechanical characteristics, including the SMB (DO-214AA) case and matte tin-plated terminals. They are designed for general-purpose regulation and protection applications requiring reliable performance across a wide temperature range.

Single Zener Diodes Replacement Considerations

Substitute parts must match the 6.2 V nominal Zener voltage, DO-214AA package, and equivalent electrical characteristics. Verify that alternative components meet the same thermal resistance and maximum power dissipation ratings under similar operating conditions.
