Nominal Voltage: The nominal voltage of this voltage regulator diode is 5.6V, meaning it provides a relatively stable 5.6V output under normal operating conditions.
Voltage Range: Despite the nominal value being 5.6V, the actual voltage range for 1SMA4734A is 5.32V to 5.92V. This indicates slight fluctuations in the output voltage within practical applications.
Accuracy: The diode's accuracy is ±5%, ensuring that the deviation from the nominal voltage does not exceed 5%, which is sufficient for most electronic device requirements.
Power Rating: The power rating of 1SMA4734A is 1W, indicating the maximum power it can dissipate safely. It's crucial to ensure the circuit's power consumption stays within this limit to avoid overheating and damage.
Reverse Leakage Current (Ir): At a reverse voltage of 2V, the reverse leakage current of this diode is 10μA. This parameter reflects the leakage current under reverse voltage conditions, important for circuits requiring precise current control.
Impedance (Zzt): The impedance of 1SMA4734A is 5Ω, describing the relationship between current and voltage in the circuit. For voltage regulator diodes, impedance affects their stabilizing performance.

Parameters of Slkor Voltage Regulator Diode 1SMA4734A
Due to its stable voltage output and moderate power handling capabilities, 1SMA4734A finds extensive application in various electronic devices, including:
Power circuits: Used to stabilize output voltage, ensuring other components in the circuit operate correctly.
Reference voltage sources: Employed in circuits needing precise voltage references.
Protection circuits: Utilized to protect other circuit elements from damage when voltages exceed specified thresholds.
Temperature compensation: Applied in circuits requiring temperature compensation due to its voltage variation characteristics with temperature changes.
Voltage regulator diodes, also known as Zener or breakdown diodes, operate based on the Zener breakdown effect. This effect causes a sharp increase in reverse current while maintaining nearly constant voltage once the reverse voltage reaches a specific threshold (Zener voltage). Typically made of silicon with a PN junction structure, these diodes operate in the breakdown region without damage, allowing current flow at higher reverse voltages while stabilizing voltage output.
Voltage stabilizers: The primary application of voltage regulator diodes is as stabilizers, leveraging the Zener breakdown effect to ensure stable voltage outputs, thereby protecting other circuit components from voltage fluctuations or surges.
Reference voltage sources: Fixed voltage outputs of Zener diodes serve as reliable reference voltage sources in circuits for comparison or calibration purposes.
Regulating devices: They can also function as regulators to adjust or limit voltage ranges within circuits, meeting specific voltage regulation needs.
Surge protection circuits: Voltage regulator diodes can limit or protect circuits by conducting when the power supply voltage exceeds their Zener voltage, safeguarding against overvoltage damage.
Arc suppression circuits: By paralleling with inductive loads, such diodes absorb high voltages generated during switch opening, effectively suppressing arcs.
This comprehensive overview highlights the critical role of 1SMA4734A and similar voltage regulator diodes in ensuring the stability and reliability of electronic circuits across various applications.
