MMSZ5252B-7-F

Single Zener Diodes Overview

The MMSZ5252B-7-F is a single Zener diode manufactured by Diodes Incorporated, designed for surface mount applications in the SOD123 package. It provides a nominal Zener voltage of 24 V with a tolerance range of 22.80 V to 25.20 V at a test current of 5.2 mA. The device supports a maximum power dissipation of 500 mW at an ambient temperature of +25°C and 370 mW at a lead temperature of +75°C. Key electrical parameters include a maximum Zener impedance of 33 Ohms at the test current and a maximum reverse leakage current of 600 nA at 18 V. The component operates within a temperature range of -65°C to +150°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a nominal breakdown voltage of 24 V
• Suitable for automated assembly processes due to surface mount packaging
• Compliant with RoHS directives and free from halogen and antimony

Single Zener Diodes Applications

• General purpose voltage regulation circuits
• Medium current protection applications
• Automated assembly manufacturing lines

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to commercial grade qualification and standard tape and reel packaging containing 3,000 units per reel. Confirm that the requested part number matches the exact Zener voltage and package type required for the design. Ensure compliance with environmental specifications such as RoHS and halogen-free status if mandated by the project requirements.

Single Zener Diodes Selection Notes

Select this component when a 24 V reference or clamp is needed in a compact surface mount footprint. The SOD123 case offers a balance between power handling capability and board space efficiency. Consider the thermal resistance characteristics and derating curves if the operating environment exceeds standard ambient temperatures or if high duty cycles are expected.

Single Zener Diodes Part Context

This part belongs to the MMSZ5252B series of 500mW surface mount Zener diodes produced by Diodes Incorporated. The series covers a wide range of voltage ratings from 2.4 V to 39 V, all sharing similar mechanical and electrical characteristics. The MMSZ5252B specifically targets applications requiring medium current handling and precise voltage clamping in consumer and industrial electronics.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 24 V nominal voltage, 500 mW power rating, and SOD123 package. Verify that alternative manufacturers provide equivalent Zener impedance and leakage current specifications to ensure circuit performance remains unchanged.
