The UMZ6.8ENTR is a Zener diode manufactured by Rohm Semiconductor. It is designed to provide voltage regulation and overvoltage protection in various electronic circuits. The 6.8E indicates a Zener voltage of approximately 6.8V. The 'TR' suffix typically indicates tape and reel packaging for automated assembly.

Applications:

• Voltage regulation: Maintaining a stable voltage in power supplies and other voltage-sensitive circuits.
• Overvoltage protection: Protecting sensitive components from voltage spikes and surges.
• Voltage clamping: Limiting the voltage to a safe level in specific circuit nodes.
• Transient voltage suppression: Protecting circuits from short-duration, high-voltage transients.
• Reference voltage generation: Providing a stable reference voltage for comparators and ADCs.

Features:

• Precise 6.8V Zener voltage: Provides accurate voltage regulation.
• Low reverse leakage current: Minimizes power loss and improves efficiency.
• Small surface mount package (SMD): Suitable for high-density PCB layouts.
• Tape and reel packaging: Facilitates automated assembly processes.
• Lead-free terminals: Complies with RoHS standards, making it environmentally friendly.

Benefits:

• Stable voltage regulation: Ensures reliable and consistent circuit operation.
• Effective overvoltage protection: Prevents damage to sensitive components.
• Compact design: Saves board space in densely populated circuits.
• Automated assembly: Reduces manufacturing costs and increases production efficiency.
• Environmentally friendly: RoHS compliant, minimizing environmental impact.

Technical Specifications: The UMZ6.8ENTR has a Zener voltage (VZ) of around 6.8V at a specified test current (IZT). It typically comes in a SOT-323 or similar small surface mount package. Other key specifications include the reverse leakage current (IR) at a specified reverse voltage and the dynamic impedance (ZZT).
