The BZX85B12 is a 1.3 Watt Zener Diode manufactured by Vishay. It is designed to provide a stable voltage reference in various electronic circuits. As it is END-OF-LIFE, it is not available for new designs.

Applications:

• Voltage Regulation
• Overvoltage Protection
• Clipping Circuits
• Voltage Reference

Features:

• Zener Voltage: 12V
• Power Dissipation: 1.3W
• Tolerance: Standard tolerance is typically ±5%.
• DO-41 Package: Standard through-hole package.
• Operating Temperature: -55 °C to +150 °C

Benefits:

• Stable Voltage Reference: Provides a consistent voltage output.
• Overvoltage Protection: Protects circuits from voltage spikes.
• Easy to Use: Simple to integrate into existing designs.

Additional Details:

The BZX85B12 Zener diode's key characteristics include its Zener voltage (Vz), reverse current (Ir), and power dissipation. The Zener voltage is the voltage at which the diode starts to conduct in the reverse direction and remains relatively constant over a range of currents. The reverse current is the small amount of current that flows through the diode when it is reverse biased below the Zener voltage. Detailed specifications can be found in the Vishay datasheet for BZX85B12. This part is noted to be END-OF-LIFE, so availability is severely limited.
