MMSZ5250B-7-F

Single Zener Diodes Overview

The MMSZ5250B-7-F is a single surface-mount Zener diode manufactured by Diodes Incorporated, housed in an SOD123 package. It provides a nominal Zener voltage of 20 V with a tolerance range of 19.00 V to 21.00 V. The device supports a maximum power dissipation of 500 mW at a lead temperature of +75°C and operates within a junction temperature range of -65°C to +150°C. Electrical characteristics include a test current of 6.2 mA, a maximum Zener impedance of 25 Ohms at the test current, and a maximum reverse leakage current of 0.1 µA at 15 V.

Single Zener Diodes Feature Summary

• Designed for general-purpose applications requiring medium current handling capabilities.
• Suitable for automated assembly processes due to its surface-mount construction.
• Compliant with AEC-Q101 standards to ensure high reliability in demanding environments.

Single Zener Diodes Applications

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required commercial qualification and packaging format. Confirm the specific tape and reel quantity aligns with production needs. Ensure compliance with RoHS directives and halogen-free requirements if specified for the project. Cross-reference the date code key to confirm manufacturing timelines.

Single Zener Diodes Selection Notes

Select this component when a 20 V reference point is required in a compact surface-mount layout. Evaluate thermal resistance values against expected ambient temperatures to ensure safe operation below maximum ratings. Compare impedance and leakage specifications against circuit sensitivity requirements to verify performance adequacy.

Single Zener Diodes Part Context

This part belongs to the MMSZ5221B through MMSZ5259B series of 500mW surface mount Zener diodes. The series offers various voltage options within the SOD123 case style. The product line is characterized by lead-free plating and green molding compounds suitable for environmentally conscious manufacturing processes.

Single Zener Diodes Replacement Considerations

Substitute parts must match the 20 V nominal voltage, 500 mW power rating, and SOD123 footprint. Verify equivalent electrical parameters such as impedance and leakage current. Automotive-grade equivalents require AEC-Q101 qualification.
