MMBZ5245BT-7-F

Single Zener Diodes Overview

The MMBZ5245BT-7-F is a single-channel surface mount Zener diode manufactured by Diodes Incorporated. It features a nominal Zener voltage of 15 V with a tolerance range of 14.25 V to 15.75 V at a test current of 8.5 mA. The device operates within a power dissipation limit of 150 mW and maintains a maximum reverse leakage current of 0.1 µA at 11 V. Electrical performance includes a maximum Zener impedance of 16 Ω at the test current and 600 Ω at knee current. The component utilizes an SOT-523 package, supports an operating temperature range from -65 °C to +150 °C, and offers a forward voltage of 0.9 V at 10 mA.

Single Zener Diodes Feature Summary

• Constructed with planar die technology for general-purpose regulation
• Compliant with lead-free and RoHS standards using matte tin plating

Single Zener Diodes Applications

• Voltage reference circuits requiring compact form factors
• General purpose voltage clamping in signal paths
• Protection against overvoltage transients in low-power electronics

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration. Confirm that the date code aligns with material specifications regarding green molding compounds if halogen-free requirements are critical. Ensure the procurement documentation references the correct electrical characteristics table for the 15V variant to validate impedance and leakage parameters during incoming inspection.

Single Zener Diodes Selection Notes

Select this component when space constraints necessitate the SOT-523 footprint while maintaining precise 15V regulation. Consider the 150 mW power dissipation limit and thermal resistance of 833 °C/W for heat management. Evaluate the low leakage current specification for high-impedance applications. Compare against other series members for alternative voltage levels or higher power ratings if system demands exceed these limits.

Single Zener Diodes Part Context

This part belongs to the MMBZ5221BT through MMBZ5259BT family of 150 mW surface mount Zener diodes. The family shares identical mechanical dimensions and mounting styles but varies in Zener voltage and test currents. The MMBZ5245BT specifically addresses the 15V segment of this portfolio, offering standardized marking codes and consistent reliability metrics across the broader product line.

Single Zener Diodes Replacement Considerations

Substitutes must match the SOT-523 package and 15V nominal voltage. Verify equivalent power dissipation and impedance characteristics. Cross-reference manufacturer-specific markings and compliance certifications to ensure functional parity without altering board layout or thermal design.
