MM3Z3V0B

Single Zener Diodes Overview

The MM3Z3V0B is a voltage regulator diode manufactured by Fairchild Semiconductor, belonging to the MM3Z series. It is designed as a general-purpose Zener diode housed in a very small SOD323 (SC-76) surface-mounted device plastic package. The component provides stable voltage regulation with a nominal voltage of 3.0 V and a tolerance selection of ±2% for the B series. It features low differential resistance and is qualified under AEC-Q101 standards for automotive applications.

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required ±2% tolerance designation (B suffix). Confirm the package type is SOD323 and ensure compliance with RoHS and Pb-free requirements. Check for AEC-Q101 qualification if the application involves automotive systems. Validate manufacturer documentation against current Fairchild or ON Semiconductor specifications.

Single Zener Diodes Selection Notes

Select this component when a precise 3.0 V reference is needed in a space-constrained design. The B series offers tighter tolerance than standard variants. Ensure the circuit operates within the specified power dissipation limits. Consider the SOD323 footprint compatibility during PCB layout. Verify thermal management requirements for the intended operating environment.

Single Zener Diodes Part Context

This component is part of the MM3Z series of voltage regulator diodes. The series includes various nominal voltages ranging from 2.4 V to 75 V. The MM3Z3V0B specifically targets applications requiring a 3.0 V regulated output. It shares common features with other members of the family, such as the small package size and low differential resistance characteristics.

Single Zener Diodes Replacement Considerations

Equivalent parts may include other 3.0 V Zener diodes in SOD323 packages from different manufacturers. Verify electrical parameters such as tolerance, power dissipation, and package dimensions before substitution. Ensure the replacement meets any specific automotive qualification requirements if applicable.
