The RD8.2FM-T1B is a Zener diode manufactured by NEC. Like other Zener diodes, it's designed to provide a stable voltage reference in electronic circuits by operating in the reverse breakdown region. This characteristic allows it to regulate voltage and protect circuits from overvoltage conditions.

Applications:

• Voltage Regulation: Used in power supplies to maintain a stable output voltage despite variations in input voltage or load current.
• Overvoltage Protection: Protects sensitive electronic components from damage caused by voltage spikes or surges.
• Voltage Clipping: Limits the voltage level in a circuit to prevent damage or unwanted behavior.
• Reference Voltage Generation: Provides a stable reference voltage for analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other precision circuits.
• Transient Voltage Suppression (TVS): Protects circuits from fast transient voltage events, such as electrostatic discharge (ESD).

Features:

• Zener Voltage: 8.2V (Nominal). The key parameter defining the voltage regulation point.
• Low Reverse Leakage Current: Minimizes current leakage when the diode is reverse biased below the Zener voltage.
• High Surge Current Capability: Allows the diode to withstand high surge currents without failing.
• Small Surface Mount Package: Suitable for automated assembly and compact circuit designs.
• RoHS Compliant: Meets environmental standards for hazardous substance content.

Benefits:

• Stable and Precise Voltage Regulation: Provides a consistent and reliable voltage reference for critical circuits.
• Enhanced Circuit Protection: Protects downstream components from damage caused by overvoltage conditions.
• Improved Circuit Performance: Contributes to the overall accuracy and stability of electronic circuits.
• Extended Component Lifespan: Prevents overvoltage conditions that can degrade or destroy other components.
• Simplified Circuit Design: Makes it easier to implement voltage regulation and protection functions in circuit designs.

Technical Specifications (Typical):

• Zener Voltage (Vz): 8.2V ± 5% at a specified test current (Iz).
• Reverse Leakage Current (Ir): Typically in the microampere range at a specified reverse voltage.
• Power Dissipation (Pd): Maximum power the diode can dissipate before failure.
• Operating Temperature Range: e.g., -55°C to +150°C.
• Package Type: e.g., SOD-323, SOT-23.
