MMSZ4702-TP

The MMSZ4702-TP is a Zener diode manufactured by Micro Commercial Components (MCC). It is designed to provide voltage regulation and protection in various electronic circuits. Here’s a detailed description of its key features and specifications:

General Description:

• Type: Zener Diode
• Package: Typically available in a DO-41 package, which is a cylindrical glass package with two leads for through-hole mounting.
• Polarity: The diode is a unidirectional device, meaning it allows current to flow in one direction while blocking it in the reverse direction, except when the reverse voltage exceeds the Zener breakdown voltage.

Electrical Characteristics:

• Zener Voltage (Vz): The MMSZ4702-TP has a Zener voltage of approximately 3.6 volts, which means it will maintain this voltage across its terminals when reverse-biased and the applied voltage exceeds this level.
• Zener Impedance (Zz): The dynamic impedance is typically low, ensuring stable voltage regulation under varying current conditions.
• Reverse Current (Iz): The maximum reverse current at the Zener voltage is specified, allowing for safe operation without damaging the diode.
• Power Dissipation (Pd): The diode can handle a maximum power dissipation of around 500 mW, which is crucial for thermal management in circuit design.

Performance Characteristics:

• Temperature Coefficient: The Zener voltage can vary with temperature, and the temperature coefficient is specified to help designers account for changes in performance under different thermal conditions.
• Surge Current Rating: The diode is capable of withstanding a certain amount of surge current, which is important for applications where transient voltages may occur.

Applications:

• Voltage Regulation: Commonly used in power supply circuits to maintain a stable output voltage.
• Overvoltage Protection: Protects sensitive components from voltage spikes by clamping excess voltage.
• Reference Voltage: Serves as a reference in various analog circuits, ensuring consistent performance.

Mechanical Characteristics:

• Lead Material: The leads are typically made of tinned copper, providing good conductivity and resistance to corrosion.
• Operating Temperature Range: The diode is designed to operate within a specified temperature range, making it suitable for various environmental conditions.

Compliance and Standards:

• The MMSZ4702-TP is compliant with various industry standards, ensuring reliability and performance in electronic applications.

In summary, the MMSZ4702-TP from Micro Commercial Components is a versatile Zener diode that offers reliable voltage regulation and protection in electronic circuits, making it a popular choice among engineers and designers.
