The CLL5235B TR PBFREE is a Zener diode manufactured by Central Semiconductor Corp. It's designed to provide stable reverse voltage regulation in various electronic circuits. The 'TR PBFREE' designation indicates that it is lead-free and suitable for applications requiring RoHS compliance. Zener diodes are specifically engineered to operate in the reverse breakdown region, maintaining a near-constant voltage across their terminals over a wide range of current variations. This characteristic makes them ideal for voltage regulation, voltage clipping, and overvoltage protection.

Applications

• Voltage Regulation: Maintaining a stable output voltage in power supplies and other voltage-sensitive circuits.
• Voltage Clipping: Limiting the voltage to a specific level to protect sensitive components.
• Overvoltage Protection: Shunting excess voltage to ground to prevent damage to downstream circuitry.
• Reference Voltage: Providing a stable reference voltage for analog circuits and instrumentation.
• Transient Voltage Suppression: Protecting circuits from voltage spikes and surges.

Features

• Precise Zener Voltage: Offers a tightly controlled Zener voltage for accurate regulation.
• Low Reverse Leakage Current: Minimizes current leakage in the reverse direction, improving efficiency.
